Grounding Information

Standard color for ground wires is green or green with yellow striping. Ground wires are not to be used as conductors carrying current. Compressor, condenser fan motor, evaporator fan motor, defrost timer, temperature control, and ice maker are grounded through an individual wire attached to electrical component and another part of refrigerator. Ground wires should not be removed from individual components while servicing unless component is removed and replaced. It is extremely important to replace all grounds prior to completing service. When nib-headed screw is used to complete grounding circuit, replace screw with a like screw.

Electrical Requirements

WARNING

Electrical Grounding Instructions -- This refrigerator is equipped with a three-prong (grounding) plug for protection against possible shock hazards. If a two-prong wall receptacle is encountered, contact a qualified electrician and have the two-prong wall receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code.

Refrigerator is designed to operate on a separate 103 to 126 volt, 15 amp., 60 cycle line.

Do not under any circumstances cut or remove the round grounding prong from the plug. Refrigerator must be grounded at all times. Do not remove warning tag from power cord.

WARNING

Sound Information

Normal Operating Sounds

This new refrigerator may be replacing a differently designed, less efficient or smaller refrigerator. Today’s refrigerators have new features and are more energy efficient. As a result, certain sounds may be unfamiliar. These sounds are normal and will soon become familiar. These sounds also indicate the refrigerator is operating and performing as designed.

• Freezer and fresh food fan air rushes and whirs.

• Sealed system (evaporator and heat exchanger) refrigerant flow gurgles, pops or sound like boiling water.

• Defrost heater sizzles, hisses or pops.

• Condenser fan air rushes and whirs.

• Compressor has a high pitched hum or pulsating sound.

• Ice cubes from ice maker drop into ice bucket.

• Ice maker water valve hookup buzzes when ice maker fills with water. This occurs whether or not refrigerator is connected to water supply. If refrigerator is not connected to water supply, stop sound by raising ice maker arm to off position.

• Foam insulation is very energy efficient and has excellent insulating capabilities. However, foam insulation is not as sound absorbent as previously used fiberglass insulation.

System Diagnosis

Refrigerant Overcharge Symptoms

• Above normal freezer temperature.

• Compressor running continuously.

• Freezing in refrigerator due to Chef’s Pantry

.• High suction and head pressure.

• High wattage.

• Warm evaporator inlet and outlet temperature.

• Below ambient suction tube temperature. Check for separated heat exchanger when suction temperature is colder than ambient.

• Refrigerant will flood out causing suction line to frost or sweat, if defrost system fails and cooling coil is not defrosted. Correct problem instead of purging refrigerant.

• Freezer colder than necessary (normal package temperature is 0° to 2°F).

• Evaporator fan motor not running.

™

Refrigerant Shortage Symptoms

• Rise in refrigerator and freezer temperatures. Warm beverages will be first indication of possible refrigerant shortage. Frozen meats and vegetables will not thaw immediately. Some freezing may occur in refrigerator section due to additional run time because of Chef’s Pantry™. Capillary line will not have full column of liquid with refrigerant shortage. A noticeable hissing sound in evaporator will be heard. Hissing should not be mistaken for regular refrigerant boiling sounds.

• Long or continuous run time.

• Traces of oil caused by leak or cracked refrigerant line.

• Lower than normal wattage.

• Compressor will feel hot due to heat generated by motor windings from continuous running. Compressor will not be as hot as it would be with full charge and long run times caused by reasons such as dirty condenser.

• Condenser will feel room temperature.

• Capillary tube will feel warmer than normal.

• If high side leak, both gauges will show lower than normal readings. As charge becomes less, readings will lower. Suction pressure gauge will probably indicate a vacuum.

• If low side leak, suction pressure gauge will show lower than normal readings, probably in a vacuum. Head pressure gauge will show higher than normal. Readings will probably rise because of air drawn in through leak is compressed by compressor and accumulates in high side (condenser) of system.

• Partial frosting of evaporator.

Restriction Symptoms

• Refrigeration cooling occurs on low pressure side of partial restriction.

• Total restriction will stop circulation of refrigerant and no cooling will occur.

• Touch refrigeration lines. Most common place for restriction is at drier filter or capillary tube inlet or outlet.

• If partial restriction there will be temperature difference at restriction point. Evaporator side will be cooler. In most cases, frost and/or condensation will be present. Longer time is required for system to equalize.

• Kinked line will cause restriction. Visually check entire system for kinks.

• Slight restriction will give same indications as refrigerant shortage with lower than normal back pressure, head pressure, wattage, and warmer temperatures.

• If total restriction is on discharge side of compressor, higher than normal head pressures and wattages will occur. This is only true while low side is being pumped out and if restriction was between compressor and first half of condenser.

Diagnose restriction by completing the following:

1. Discharge system.

2. Replace drier-filter.

3. Evacuate and recharge system with specified

refrigerant charge.

If refrigerator performs normally, the following conditions may exist:

• refrigerant loss

• partially restricted drier

• moisture in system

If refrigerator performs as previously described, capillary line or condenser may be restricted. Locate and correct restriction point.

Restriction reduces refrigerant flow rate and heat removal rate. Total restriction may be caused by moisture, poorly soldered joint, or solid contaminants in system. Moisture freezes at evaporator inlet end of capillary tube. Solid contaminants collect in drier. Wattage drops because compressor is not circulating normal amount of refrigerant.

If restriction is on low side suction, pressure will be in a vacuum and head pressure will be near normal. If restriction is on high side, suction pressure will be in a vacuum and head pressure will be higher than normal during pump out period. In both cases, it will take longer than 10 minutes for head pressure to equalize with low side after compressor stops.

November 1996 11 RS1200001

Page 12

System Diagnosis

Air in System Symptoms

Air in system can be caused by low side leak or improper servicing. If low side leak occurs, temperature control will not achieve temperatures and compressor will run continuously. Compressor will eventually pump low side into a vacuum, drawing air and moisture into system. Air and R134a do not mix. Air pressure will be added to normal head pressure, resulting in higher than normal head pressures.

Determine if air is present by reading head pressure gauge with refrigerator off and evaporator and condenser at same temperature. Verify temperature on condenser outlet tube. Temperature should be within 3° or 4°F of what "Pressure and Temperature Relationship Chart" shows for a given idle head pressure. If temperature of condenser outlet is considerably lower than idle head pressure of gauge, air is in system.

Diagnose air in system by completing the following:

1. Thoroughly check for leaks.

2. Correct leak source. Do not attempt to purge air off. This could result in an undercharged system.

3. Discharge system.

4. Replace drier-filter.

5. Evacuate and recharge system with specified refrigerant charge.

When ambient temperature is below cut-in of temperature control, compressor will not operate.

Drain traps will freeze in ambient temperatures of 32°F.

Heat Load Symptoms

Increased heat load can result from addition of large supply of foods, excessive door openings, poor door sealing, interior light remaining on, etc.

Increased heat being absorbed by refrigerant in evaporator will affect temperature and pressure of gas returning to compressor. Refrigerator and freezer temperatures, power consumption, discharge, and suction pressures are all affected by heat load. Pressures will be higher than normal under heavy heat load.

Low or High Ambient Temperature Installation Symptoms

Lower ambient air temperature reduces condensing temperature and temperature of liquid entering evaporator. Increase in refrigeration due to operation in lower ambient results in decrease in power consumption and run time. At lower ambients there is reduction in cabinet heat leak which is partially responsible for lower power consumption and run time.

An increase in refrigeration will not occur below certain minimum ambient temperature. Temperature varies with type and design of refrigerator.

Ambient temperatures lower than 55°F will affect efficiency. The higher the ambient temperature, the higher the head pressure must be to raise the high side refrigerant temperature above condensing medium. Head pressure will be higher as ambient temperature raises. Refrigerators installed in ambient temperatures lower than 55°F will not perform effeciently because system pressures are generally reduced and unbalanced. Lower head pressure forces less liquid refrigerant through capillary line, resulting in symptoms of refrigerant shortage. The lower the ambient temperature, the more pronounced the condition.

HFC134a Service Information

HFC134a is alternative refrigerant for CFC12. HFC134a has an ozone depletion potential (ODP) factor of 0.0 and a global warming potential (GWP) factor of 0.27. HFC134a is not flammable and has acceptable toxicity levels. HFC134a is not interchangeable with CFC12. There are significant differences between HFC134a and CFC12 which must be considered when handling and processing refrigeration system.

Health, Safety, and Handling

Health, safety and handling considerations for HFC134A are virtually no different than those for CFC12.

Health, Safety, and Handling CFC12 HFC134a

Allowable overall exposure limit 1,000 ppm Same Vapor exposure to skin No effect Same Liquid exposure to skin Can cause frostbite Same Vapor exposure to eye Very slight irritant Same Liquid exposure to eye Can cause frostbite Same

Caution

To minimize contamination, exercise extreme care when servicing HFC134A sealed systems.

• No trace of other refrigerants is allowed in HFC134a systems. Chlorinated molecules in other refrigerants such as CFC12, etc. will lead to capillary tube plugging.

• Ester oil is used in HFC134a systems. Do not use mineral oil. HFC134a and mineral oils cannot be mixed. If mineral oils were used in HFC134a systems, lubricant would not return to compressor and would cause early compressor failure. If significant amount of oil has been lost from compressor, replace oil rather than adding oil.

• Ester oils used in HFC134a systems are so hydroscopic that by the time an inadequate system performance is detected, oil will be saturated with moisture.

• CFC12 has much higher tolerance to system processing materials, such as drawing compounds, rust inhibitors, and cleaning compounds, than HFC134a. Such materials are not soluble in HFC134a systems. If materials were to be washed from system surfaces by ester oils, they could accumulate and eventually plug capillary tube.

• Care must be taken to minimize moisture from entering HFC134a system. Do not leave compressor or system open to atmosphere for more than 10 minutes. Excessive moisture in HFC134a system will react with compressor oil and generate acid.

• Compressor must be replaced when performing low side leak repair.

• Drier filter must always be replaced with service drier filter, part #B2150504.

Important: Unbrazing drier filter from tubing will drive moisture from desiccant and into system, causing acids to form. Do not unbraze filter drier from tubing. If CFC12 service drier was installed in HFC134A system, drier could overload due to excessive moisture.

• HFC134a compatible copper tubing, part #R0174075 (1/4" O.D. X 18" length) and part #R0174076 (5/16" O.D. X 24" length) must be used when replacing tubing.

• Avoid system contamination by using Towerdraw E610 evaporating oil, part # R0157532, when flaring, swaging, or cutting refrigeration tubing.

• Heat trap paste

• ICI appliance grade HFC134a

Drier Replacement

Prior to opening refrigeration system, recover HFC134a refrigerant for safe disposal.

Every time sealed HFC134a system is repaired, drier filter must be replaced with, part # B2150504.

Cut drier out of system by completing the following steps. Do not unbraze drier filter. Applying heat to remove drier will allow moisture into system.

1. Score capillary tube close to drier and break.

2. Reform inlet tube to drier allowing enough space for large tube cutter.

3. Cut circumference of drier at 1-1/4", below condenser inlet tube joint to drier.

4. Remove drier.

5. Apply heat trap paste on post condenser tubes to protect grommets from high heat.

6. Unbraze remaining part of drier. Remove drier from system.

7. Discard drier in safe place. Do not leave drier with customer. If refrigerator is under warranty, old drier must accompany warranty claim.

DANGER

To avoid death or severe personal injury, cut drier at correct location. Cutting drier at incorrect location will allow desiccant beads to scatter. Completely clean area of beads, if spilled.

HFC134a Service Information

Replacement Service Compressor

HFC134a service compressors will be charged with ester oil and pressurized with dry nitrogen. Before replacement compressor is installed, pull out 1 rubber plug. A pop from pressure release should be heard. If a pop sound is not heard, do not use compressor. Positive pressure in compressor is vital to keep moisture out of ester oil. Do not leave compressor open to atmosphere for more than 10 minutes.

Compressor Testing Procedures

• Refer to “Temperature and Relationship Chart” for operating watts, test points, and temperature relationship test.

• Temperature testing is accomplished by using 3 lead thermocouple temperature tester in specific locations. Test point T-1 is outlet on evaporator coil and T-2 is inlet. Test point T-3 is suction tube temperature midway between where armaflex ends and suction port of compressor (approximately 12 inches from compressor).

• Thermocouple tips should be attached securely to specified locations.

• Do not test during initial pull down. Allow one off cycle or balanced temperature condition to occur before proceeding with testing.

• Refrigerator must operate minimum of 20 minutes after thermocouples are installed.

• Turn control to colder to obtain required on time.

• Wattage reading must be recorded in conjunction with temperature test to confirm proper operation.

• Suction and head pressures are listed on “Temperature and Relationship Chart” Normally these are not required for diagnosis but used for confirmation on systems which have been opened.

WARNING

To avoid death or severe personal injury, never use oxygen, air or acetylene for pressure testing or cleanout of refrigeration system. Use of oxygen, air, or acetylene may result in violent explosion. Oxygen may explode on contact with oil and acetylene will spontaneously explode when under pressure.

Leak Testing

Undetected leaks lead to repeated service calls and eventually result in system contaminations, restrictions, and burned out compressors.

After recharging, sealed system must be thoroughly tested for leaks. If a very small leak is difficult to isolate, coat area with soap suds and observe location of bubbles.

HFC134a Service Information

WARNING

To avoid severe personal injury or death from fire keep system free from contamination due to presence of air. Follow instructions exactly.

Before opening system evaporator coil must be at ambient temperature to minimize moisture infiltration into system.

1. After capturing refrigerant, replacing drier and making any repairs, evacuate system from high side through drier/process tube and low side through compressor process tube simultaneously. Evacuation should not be done through line piercing valve but through I.D. opening of tubes.

2. With valves “C” and “F” closed to thermistor vacuum gauge and charging cylinder, open all other valves and start vacuum pump.

3. At approximately 29 inches of vacuum, open valve “C” to thermistor vacuum gauge and take micron reading.

4. Continue evacuating system until thermistor vacuum gauge registers 600 microns.

5. At 600 microns close valve “A” to vacuum pump to allow micron reading in system to balance. Micron level will rise. If in 2 minutes, micron level stabilizes at 1000 microns or below, system is ready for charging.

• If micron rises above 1000 micron level and

stabilizes, open valve “A” to vacuum pump and continue evacuating.

• If micron reading rises rapidly and does not

stabilize, a leak still exists in system. Close valve “A” to vacuum pump and “C” to thermistor vacuum gauge. Invert charging cylinder and open charging cylinder valve “F” to add partial charge for leak checking. With leak detector, check manifold connections and system for leaks. After locating leak, capture refrigerant charge, repair leak, and begin at step 1.

6. Once system is ready to charge, close valve “A” (vacuum pump), “C” (thermistor vacuum gauge), and “E” (low side manifold gauge).

7. Check serial plate for correct charge and set scale on dial-a-charge cylinder for corresponding HFC134a pressure reading. Do not use captured or recycled refrigerant in Amana® refrigerators. Use

of captured or recycled refrigerant voids any warranty.

8. Open valve “F” to charging cylinder and let exact amount of refrigerant out of cylinder. Close valve. Low side gauge pressure should rise shortly after opening charging cylinder valve as system pressure equalizes through capillary tube. If pressure does not equalize, a restriction typically exists at capillary/drier braze joint.

9. If no restriction exists, open valve “E” (low side manifold gauge) and pinch off high side drier process tube.

10. Start compressor and draw remaining refrigerant in charging hoses and manifold into compressor through compressor process tube. To check high side pinch-off drier process tube, close valve “D” (high side gauge). If pinch-off is not leaking, high side pressure will not rise. If high side pressure gauge shows an increase, repeat high side pinchoff and open valve “D”. Repeat until high side pinch-off no longer leaks.

11. Pinch-off compressor process tube and remove charging hose. Braze stub closed while compressor is operating.

12. Unplug refrigerator from electrical outlet. Remove charging hose and braze high side drier process tube closed.

Capacitor Run capacitor connects to relay terminal.

Capillary tube

Capillary is sized in diameter and length to feed proper amount of refrigerant to evaporator.

Capillary is soldered to suction line to transfer heat from capillary and add additional superheat to gas refrigerant in compressor suction line.

WARNING

To avoid electrical shock which can cause severe personal injury or death, discharge capacitor through a resistor before handling.

1. Disconnect power to refrigerator.

2. Remove capacitor and disconnect capacitor wires.

3. Discharge capacitor by shorting across terminals with a resistor for 1 minute.

4. Check resistance across capacitor terminals with ohmeter set on "X1K" scale.

• Needle should jump towards 0 ohms and quickly move back to infinity.

• If needle does not move, the capacitor is open.

• If needle reads a constant value at or near 0 ohms, the capacitor is shorted.

• If needle jumps towards 0 and then moves back to a constant high resistance (not infinity), the capacitor has a high resistance leak.

Capillary discharges into evaporator.

Compressor When compressor electrical circuit is energized, the

amount of starting time the start winding circuit turns off. PTC relay will switch off the start winding circuit even though compressor has not started (as when attempting to restart after momentary power interruption).

With "open" PTC relay, compressor will not start because there is little or no current to start windings. Overload protector will open due to high locked rotor run winding current.

With "shorted" PTC relay or capacitor, compressor will start and overload protector will quickly open due to high current of combined run and start windings.

With open or weak capacitor, the compressor will start and run as normal but will consume more energy.

Check for resistance between: Terminals "S" & "C" Terminals "R"& "C"

Ground Test Disconnect power to refrigerator .Remove compressor leads and use an ohmmeter set on highest scale. Touch 1 lead to compressor body (clean point of contact) and the other probe to each compressor terminal. If a reading is obtained, compressor is grounded and must be replaced.

Operation Test If motor winding tests fail to show cause for failure:

1. Disconnect power to refrigerator. Wire a test cord to disconnect switch.

2. Place time delayed fuse, with U.L. rating equal to amp rating of motor, in test cord socket.

3. Remove overload and relay.

4. Connect start, common, and run leads of test cord on appropriate terminals of compressor.

5. Attach capacitor leads of test cord together. If capacitor is used, attach capacitor leads to a good capacitor of same capacity.

6. Plug test cord into volt-watt meter to determine start and run wattage as well as check for low voltage which can also be a source of trouble.

7. With power to volt-meter, press start cord switch and release. If compressor motor starts and draws normal wattage compressor is okay and trouble is in capacitor, relay, overload, freezer temperature control, adaptive defrost control, or elsewhere.

See “Ice Maker” section for service information.

Condenser

Condenser is a tube and wire construction located in compressor compartment. Condenser is on high pressure discharge side of compressor.

Refrigerant flows from compressor into a precondenser serpentine below drain pan to evaporate defrost water. From serpentine, refrigerant flows into pre-condenser loop (Yoder loop) foamed around freezer door opening to help control external condensation around freezer door and on flange. Higher pressure refrigerant gas is routed to condenser

because discharged gas is at higher temperature than air that is passing over condenser.

Condenser is air cooled by fan motor. It is very important that adequate air flow over condenser is maintained. If efficiency of heat transfer from condenser to surrounding air is impaired, condensing temperature becomes higher. Higher temperature liquid means less heat will be removed during boiling in evaporation. This is indicated by higher that normal head pressures, long run time, and high wattage. Remove any lint, dust accumulation, etc. that would

• Leaks in condenser can usually be detected by using an electronic leak detector or soap solution. Look for signs of compressor oil when checking for leaks. A certain amount of compressor oil is circulated with refrigerant.

• Leaks in post condenser loop are rare as loop is a 1 piece copper tube.

• In cases of minute leaks it may be necessary to separate condenser from rest of refrigeration system and pressurize condenser up to a maximum of 235 PSI with a refrigerant and dry nitrogen combination.

WARNING

• Protect against a sudden eruption if high pressures are required for leak checking.

• High pressure compressed cases should never be used in

Inner volume of evaporator allows liquified refrigerant discharged from capillary to expand into refrigerant gas.

Act of expansion cools evaporate tube and fin temperature to approximately -20°F, transfering heat from freezer section to refrigerant.

Passing through suction line to compressor, the refrigerant picks up superheat (a relationship between pressure and temperature that assures complete vaporization of liquid refrigerant) as result of capillary being soldered to suction line.

Refrigerant gas is pulled through suction line by compressor to complete refrigerant cycle.

See "Electronic Functional Description, Adaptive Defrost Circuitry"

Drier is placed at P.C. loop outlet and passes liquified refrigerant to capillary.

Drier must be changed whenever sealed refrigeration system is opened.

Drier used in R12 sealed system is not interchangeable with drier used in R134a sealed system. Replace drier with part #B2150504.

Leaks in evaporator can usually be detected by the use of electronic leak detector or soap solution. Compressor oil is circulated with refrigerant so look for oil when checking for leaks.

For minute leaks separate condenser from rest of refrigeration system and pressurize condenser up to a maximum of 140 PSI with a refrigerant and dry nitrogen combination. Recheck for leaks.

Check resistance across heater.

Check defrost system by thermocoupling defrost thermostat and plugging refrigerator in wattmeter. Force into defrost mode. Wattmeter should read specified watts (according to tech sheet) ± 20 watts. When defrost thermostat reaches specified temperature (according to tech sheet) ± 5°F., thermostat should interrupt power to heater.

Adaptive Defrost Operation

• Defrost occurs after predetermined length of compressor run hours. Compressor run time between defrost changes or adapts, depending upon recent history of defrost lengths (time it takes for defrost terminator to open once defrost heater has been turned on). Defrost terminator opens at 55°F (13°C) and closes at 20°F (-7°C).

• Compressor run time between defrost (CRTD) will be one of 3 values under normal operation: CRTD (1), or CRTD (2) or CRTD (3) defined as 8, 12, and 16 hour lengths. If defrost length is low (DT-LO defined as 21 minutes) indicating small frost load CRTD for next defrost cycle is advanced to next level. If defrost length is high (DI - HI defined as 24 minutes) indicating large frost load CRTD for next defrost cycle is lowered to next level. Initial value at power CRTD (0) is 4 hours.

• Vacation mode CRTD equals 96 hours. Vacation mode CRTD is interrupted with door openings. Defrost interval will revert back to the previous interval before Vacation mode.

• Six minute dwell time occurs after defrost terminator opens before compressor and condenser fan motor will operate. Ten minute dwell time occurs after defrost terminator opens before evaporator fan motor will operate.

• Conventional defrost can be selected.

Indicator lights 5 through 8 represent ones digit with 5 being the most significant bit. Indicator light 9 (coldest is + - sign; light glows signifying negative value).

2. Choose refrigerator thermistor temperature display by pressing Ref Temp pad. Refrigerator temperature indicator light will glow. Temperature display will show thermistor temperature in BCD as described above.

performed in Mode B by pressing Max Ref pad. Max Ref light will glow. One temperature indicator should glow indicating present Max Ref run time duration. Pressing Warmer pad decreases Max Ref run time by 2 hours and pressing Colder pad increases by 2 hours. Times are from 6 hours (indicated by 1 temperature indicator) to 22 hours (indicated by coldest temperature indicator). Default Max Ref run time is 10 hours.

3. Max Frz run time duration adjustment can be performed by pressing Max Frz pad in Mode B. Max Frz indicator will glow. Adjustment process is same as items 1 and 2. Duration times are in increments of 4 hours, ranging from 8 hours. 1 setting to 40 hours at coldest setting. Default Max Frz run time duration is 24 hours.

4. Refrigerator temperature offset is calibration adjustment. Temperatures at which refrigerator cuts-in and cuts-out are shifted by amount offset is set. Pressing Ref Temp pad while in Mode B causes refrigerator indicator to glow and 1 of 9 temperature indicators to glow. Pressing Warmer pad or Colder pad moves offset up or down range. Temperature indicators and offsets and what they imply are shown on chart below. The low voltage board freezer offset temperature is 0 and refrigerator offset temperature +2 from factory.

5. Enable freezer temperature offset by pressing Freezer Temp pad in Mode B. Freezer indicator will glow. Adjustment process, set point values, is identical to item 4.

Electronic control value column is calculated in units of °F. Conversion is °C = (°F - 32)/1.8.

Mode B Functions

1. Door alarm delay can be adjusted from keyboard when in this mode. Press Alarm Off pad, door open indicator will glow. One temperature indicator should glow indicating present delay time setting. Pressing Warmer pad decreases delay by 1 and pressing Colder pad increases delay by 1. Delay times selected go from 1 to 9 minutes in 1 minute increments.1 being 1 minute and 9 being 9 minutes.

Circuitry

Refer to “Technical Data Sheet”, part #12074201, for Wiring Schematic.

Freezer Compartment Refrigeration Cycle Circuitry

As freezer thermistor warms, resistance lessons, allowing low voltage signal to be sent to electronic control. In turn, 2 low voltage signals are sent by electronic control. One to compressor relay coil (C1) and another to evaporator fan relay coil (F1). With both relay coils energized and contacts closed, high voltage circuits to compressor, condenser fan motor, and evaporator fan motor are complete.

As thermistor cools during refrigeration cycle, resistance through thermistor increases, blocking low voltage signal to electronic control, interrupting the cycle.

Fresh Food Compartment Refrigeration Cycle Circuitry

As fresh food thermistor warms, resistance lessens, allowing low voltage signal to be sent to electronic control. In turn, electronic control sends low voltage signal to 24 VDC fresh food fan.

When fresh food fan motor operates, freezer air is circulated into fresh food compartment. As fresh food thermistor cools, resistance increases, blocking low voltage signal to electronic control. In turn, electronic control interrupts the signal to fresh food fan motor.

Fresh Food and Freezer Compartment Refrigeration Cycle Circuitry

Many times cooling will be called for in both compartments as both freezer and fresh food thermistors warm. Resulting is electronic control signaling for compressor, condenser fan motor, evaporator fan motor, and 24 VDC fresh food fan to operate. Once freezer thermistor has been cooled sufficiently to block the signal to electronic control, the compressor, condenser fan motor, and evaporator fan motor will shut down. However, fresh food fan motor will continue to function until fresh food thermistor cools and blocks the signal to electronic control.

If fresh food thermistor is cooled prior to freezer thermistor, the electronic control will interrupt the signal to the fresh food fan motor. The compressor, condenser fan motor, and evaporator fan motor will remain in operation through freezer thermistor.

Adaptive Defrost Circuitry

After proper compressor run time (either 8, 12, or 16 hours), refrigeration cycle is interrupted and a low voltage signal is sent form electronic control to defrost relay coil (D1 DEF). Powering of relay coil closes relay contact (D1), completing the high voltage circuit to the defrost heater through the closed defrost terminator (closes at 20°F (-7°C)). The isolator, part of high voltage PC board, recognizes the presence of line voltage to the defrost heater. Isolator sends a low voltage signal to electronic control which keeps count of the number of minutes defrost terminator remains closed (opens at 55°F (13°C)). Length of time defrost terminator remains closed, determines whether next defrost cycle advances by 4 hours of compressor run, stays at same interval or backs up by 4 hours of compressor run. If defrost terminator does not open before 30 minutes, defrost cycle will automatically be terminated by electronic control and refrigeration cycle will resume after a 6 minute dwell time.

Important: When Showroom switch is off, isolator see's line voltage. In turn, isolator keeps electronic controller from signaling compressor, condenser fan motor, and evaporator fan motor relay coils and keeps fresh food fan motor off.

Ice Maker

Operation

Thermostat closes when temperature reaches 17° ± 3°F (-8.3° ± 1.5°C). Current flows through thermostat to motor. See “Ice Maker Wiring Diagram”. Motor is linked with drive gear. From module, there are copper contacts that ride on copper strips on backside of drive gear. As the drive gear rotates, contacts will make or break a circuit (tract) to the copper strips to operate ice maker.

All components can be tested without removing ice maker or moving refrigerator away from installation. Remove cover.

Test points are identified on module:

N = Neutral side of line M = Motor connection H = Heater Connection T = Thermostat connection L = L1 side of line V = Water valve connection

Specifications

Mold heater: 185 watts, 264 ohms Thermostat: Close 17 ± 3°F (-8 ± 1°C)

(bimetal) Opens 32° ± 3°F (0°± 1°C) Water fill: 140 cc, 7.5 sec. Motor cycle: Stamped in circuit.

Plug in connectors. One revolution of blades takes 3 minutes plug stall time on ice (eject and water fill).

Testing Procedures

Verify ice maker has power, shut-off arm is down, and freezer is cold enough to close bimetal thermostat.

• Test point L and N will verify 120 volts to ice maker module.

• Test points T and H will verify bimetal thermostat is open or closed.

• Verify test probes go into test points 1/2 inch (1.25 cm).

1. Short T and H with a shunt (insulated 14 gauge wire

with ends stripped back 5/8 inch (1.6 cm)) to run motor. If motor runs, replace bimetal thermostat. If motor does not run, replace module.

2. Leave jumper in for half of revolution. Touch

heater mold. If heater mold feels warm, heater is working properly.

3. Remove jumper. Water valve will be energized in

last half of revolution if mold heater has not failed.

If water valve adjustment screw falls out, put screw in hole and align as shown below.

Water adjustment screw

Thermostat, mold heater, and wiring harness are replaceable. Any other failure, including motor, requires replacement of module assembly. Replacement mold assembly comes with new mold heater installed.

Thermostat

1. Remove control box from mold by removing screws.

Screws

2. Pull front of black housing free of mold. Thermostat is on mold side.

Thermostat

When small hole is centered in large hole, water fill adjustment is 7.5 seconds (normal fill time).

Water Problems

Poor water quality can cause ice maker to fail or produce unacceptable cubes. Mineral content or sand can restrict screen in water fill valve or particle of sand can keep valve from seating properly.

If water valve does not close, the following could occur:

• no ice production

• small or hollow ice cubes

• flooding of ice container Install water filter, part #R0183114, to eliminate bad

taste, odor, and visible contaminates. Mineral contact can cause lime build up in mold.

Wicking of water over mold and poor cube release can occur. Silicone is applied at upper edges around fill cup and stripper.

Temperature Problems

Freezer temperatures above normal 0° ± 2°F (-18°±1°C) will slow down ice production. Increase ice production by setting freezer to colder setting. Thermostat cycling temperature (1 revolution ice maker) is 17° ± 3°F (-8° ± 1°C). Ice will freeze when these temperatures are achieved. Cycling time will be slower if freezer temperature is not cold enough to achieve mode temperatures easily.

Retaining clips

3. Grasp 1 thermostat clip and pull out.

4. Press in new thermostat. Verify pins are properly indexed. Electrical assembly does not need to be removed. If replacing module, transfer clips to new mold support. Use new thermal bonding material.

Wiring Harness

Remove wiring harness by pressing retaining tab and pulling forward.

Ice Maker

Caution

To avoid property damage, test for water leaks after repair or replacement of water valve. Do not overtighten connection to household water supply.

Water Valve

Water valve has 1 solenoid. Valve has 80 mesh screen water strainer. When tan encapsulated solenoid is energized, the amount of water entering ice maker mold is directly proportional to length of time water valve switch is held closed by timing cam.

Inside valve is a flow washer which acts as a water pressure regulator. Proper ice maker fill is 140 cc ± 10cc at 7.5 seconds of water fill at an inlet pressure ranging from 20 to 120 PSI (1.4 to 8.2 bar).

Wiring Harness

A nonresettable thermal fuse micro device 170°F (78°C) is spliced into red wire of ice maker wiring harness. Fuse will protect freezer plastic liner from melting if ice maker should overheat. Excessive heat can cause no ice production. Replacing wiring harness will only temporarily solve problem. Replace ice maker thermostats.
