IF UNIT IS UNDER A SOLID SOFFIT AND CLEARANCE BETWEEN SOFFIT AND TOP OF UNIT IS GREATER THEN 1” (25.4 mm), OR IF UNIT IS NOT UNDER SOLID SOFFIT, UNIT COULD TIP FORWARD UNDER CERTAIN LOAD CONDITIONS. FAILURE TO INSTALL ANTI-TIP COMPONENTS AND EXTEND LEVELERS TO FLOOR ACCORDING TO INSTALLATION MANUAL COULD RESULT IN SERIOUS INJURY OR DEATH.

INSTALLATION CONSIDERATIONS

This section covers common installation issues seen by Service Technicians. Improper installation, though not a valid service issue, has the potential to lead to a call for service. Installation related complaints could include, but are not limited to: Unit leveling, unit movement, door misalignment, improper door and drawer sealing, internal frost or condensation, exterior condensation, warm compartment temperatures, etc.

NOTE: If additional installation information is needed, refer to the complete Installation Guide, or contact Sub-Zero Service Department.

Anti-Tip Components Installation (All Models)

If anti-tip components (aka wood block / blocking kit) need be installed, follow these steps:

NOTE: These directions are supplied with each anti-tip package.

1. Locate and mark two wall studs at back of unit installation location (See Figure 2-1).

2. Identify and mark proper height to clear unit top. Space between unit top and bottom of wood block must NOT be more then 1/4" (6.1 mm) (See Figure 2-1).

3. Using the L-brackets and screws provided, secure wood block to wall studs, located in step 1, making sure screws extend 7/8" (22.2 mm) into each wall stud. The wood block must extend a minimum of 3" (76.2 mm) over unit (See Figure 2-1).

4. Utilizing front and rear levelers, raise and level unit until it contacts wood block.

5. Refer to Installation Guide provided with the unit for any additional information needed.

Term/Component

Definition / Description

Control Board …………………………..The printed-circuit board (PC Board) contains the microprocessor, relays and

electrical connections which control and monitor all functions and operations of the unit.

Microprocessor ………………………... An electrical component on the control board which receives electrical signals

from other components, processes that information, then sends an electrical signal to the relays on the board to open or close, and other electronic components in the unit to switch on or off.

Relay …………………………………… The electrical components on the control board which switch other compo-

nents in the unit ON and OFF when instructed to do so by the microprocessor.

LCD (Liquid Crystal Display) ……...... That part of the control board seen at the control panel which displays com-

partment temperatures, service indicator, door ajar alarm bell & ice indicator.

Control Panel Assembly ………………The information input and read-out area of the electronic control system,

located at the top of the upper Compartment.

Membrane Switch …………………….. An integral part of the control panel assembly, which consists of the function

keys used for all input operations to the electronic control system.

Keys (Function Keys) ………………… The buttons on the Membrane switch used for input operations. (The keys

are: UNIT ON/OFF, ALARM ON/OFF, ICE ON/OFF, WARMER, COLDER)

Indicators .....…………………………... The words and numbers that are displayed at the control panel assembly.

(Example: Temperature displays, alarm bell indicator, SERVICE indicator, and ICE system indicator)

Error Codes .…………………………... The code numbers accompanied by the letters “EC” that appear on the LCD

during diagnostic mode if the unit experienced specific problems related to electrical signals supplied by electrical components.

Display Units of Measure……………...Temperatures displayed at the LCD may be in fahrenheit units of measure

(°F) or celsius units of measure (°C). A series of key strokes allows the temperature display units of measure to be switched to read as either °F or °C.

Set-Point ……………………………….. The desired compartment temperature, established by pressing the COLDER

or WARMER keys.

High Offset (Cut-in)………………….....As the compartment air temperature cycles up and down, the high offset is

the maximum compartment temperature that the electronic control system will allow before calling for cooling.

Low Offset (Cut-out)…………………... As the compartment air temperature cycles up and down, the low offset is the

minimum compartment air temperature that the electronic control system will allow before interrupting cooling.

Thermistor (Temperature Sensor) ….. A resistor with which resistance changes as the temperature around it

changes. For electronic control system purposes, the microprocessor measures this resistance and displays it as a temperature reading at the LCD.

Monitor, Regulate and Display Compartment Temperatures

Temperature signals from thermistors in refrigerator and freezer compartments are monitored, then displayed on the LCD. When a compartment reaches high offset temperature (calling for cooling), the compressor and evaporator fan are switched on. (See Figure 3-11). When a compartment reaches low offset temperature, the compressor and evaporator fan are switched off. Though compartment air temperature fluctuates from off and on cycles, the “average” temperature is displayed. (See Figure 3-12)

NOTE: Freezer compartment temperature range is -5°F (-21°C) to +5°F (-15°C). Refrigerator compartment temperature range is +34°F (+1°C) to +45°F (+7°C).

NOTE: If average compartment temperature changes, the display will change by one degree per minute.

NOTE: A refrigerator compressor will not energize after a refrigerator off-cycle defrost unless the evaporator ther-

mistor detects temperatures 38°F (3°C), or above.

NOTE: After a freezer evaporator defrost, the freezer compressor is not energized until after the 5 minute time delay/dwell that follows all freezer defrosts.

NOTE: If a refrigerator compartment thermistor is faulty, the refrigerator compressor defaults to 20 minutes on, 40 minutes off cycling, EE appears at right in LCD, SERVICE flashes and Error Code 05 is logged.

NOTE: If a refrigerator evaporator thermistor is faulty, the refrigerator compressor will not energize until compartment air temperature exceeds high offset by 5°F (3°C). SERVICE flashes and Error Code 06 is logged.

NOTE: If a freezer compartment thermistor is faulty, the freezer compressor defaults to 20 minutes on, 20 minutes off cycling, EE appears at left in LCD, SERVICE flashes and Error Code 07 is logged.

NOTE: If in Sabbath Mode, the compartment thermistors still control compressor operation, except that when high offset is reached, there is a random 15 to 25 second delay before compressors are energized.

Control Condenser Fan Operation

The microprocessor senses the 115 volt AC output to both compressors. If either compressor is running, a signal is sent to the condenser fan relay on the control board to close, supplying power to the condenser fan (See Figure 3-

13). If both compressors are off, the condenser fan will be off.

NOTE: In single compressor models (601R-2, 601RG-2, 601F-2), power to the condenser fan is supplied by the compressor circuit. The white/red wire from the control board will not be present in those models.

NOTE: In models 611G-2 and 650G-2, the condenser fan relay also controls the door heater.

Minimize Condensation on Refrigerator Door Glass (Models Produced with Glass Doors Only)

On models produced with glass doors, the refrigerator door is equipped with a 5 watt braided wire heater around the glass perimeter to help minimize condensation formation on the glass.

• The heater in a 601RG door is on 100%.

• The heater in 611G-2 and 650G-2 doors is tied into the condenser fan circuit (see Control Condenser Fan Operation on preceding page and Figure 3-14 below).

To help minimize condensation on the glass further, the microprocessor detects when the refrigerator door is opened, via the light switch, then when the door closes, the evaporator fan is energized for 5 minutes. This draws any warmer moist air away from the door glass. (See Figure 3-14)

NOTE: The evaporator fan in these models also cycles with the compressor.

Monitor and Control Refrigerator Off-Cycle Defrost

Temperature signals from the refrigerator compartment evaporator thermistors are monitored by the microprocessor. During off cycle defrost, if the compartment temperature reaches high offset before the evaporator rises to 38°F (3°C), the signal to run the compressor and evaporator fan will wait, allowing the refrigerator evaporator to fully defrost before the compressor is energized (See Figure 3-15).

NOTE: If a refrigerator comp

artment thermistor is faulty, the refrigerator compressor defaults to 20 minutes on, 40

minutes off cycling, EE appears at right in LCD, SERVICE flashes and Error Code 05 is logged.

NOTE: If a refrigerator evaporator

thermistor is faulty, the refrigerator compressor is not energized until compart-

ment air temperature exceeds high offset by 5°F (3°C). SERVICE flashes and Error Code 06 is logged.

Monitor and Control “Adaptive Defrost” of Freezer Evaporator

Initially, the freezer compressor cycle-runs 12 hours. The control board defrost relay is then closed, supplying power to the defrost, drain tube and fill tube heaters. The compressor, condenser fan and evaporator fan are switched off.

With “Adaptive Defrost”, the length of time the defrost heater stays on to open the defrost terminator bimetal (55°F/13°C), is observed by the microprocessor via the grey w/white stripe wire to J4. This length of time is used to calculate the number of hours before the next defrost (defrost interval). If the heater then stays on for a shorter time period, the microprocessor increases the next defrost interval. If the heater then stays on for a longer time period, the microprocessor decreases the next defrost interval. (See Figure 3-16) This is an ongoing process whereby the defrost time and the defrost interval will vary by unit use.

NOTE: A 5 minute time delay/dwell follows all defrosts, during which the drain tube and fill tube heaters remains energized. At the end of the 5 minute dwell, the compressor, evaporator fan and condenser fan are energized, and the drain tube heater is switched off.

NOTE: Minimum defrost interval = 6 hours of compressor run time; Maximum defrost interval = 80 hours of compressor run time; Maximum defrost duration = 20 minutes, plus 5 minute dwell.

NOTE: If the defrost sensing line is open, defrost operation defaults to 25 minute defrost time / 6 hour build time, and Error Code 22 is logged. If the evaporator thermistor detects an under-heat or overheat situation at the same time, Error Codes 20 or 23 is logged, respectively.

NOTE: During defrost, the displayed temperature is locked.

Figure 3-18. SERVICE & EC Flashing = Several Excessive Compressor Run Periods

Monitor Compressor Run Duration, Displays If Service is Needed (Starting with Serial #2092137)

The microprocessor observes the changing state of the compressor relays to determine the length of compressor run time (See Figure 3-17). If a compressor runs 100% (Fre = 6 hours / Ref = 4 hours), an error code is logged (EC 40 / EC 50, respectively), and defrost is initiated, but SERVICE will not

flash.

If several 100% run periods occur, and the compartment temperature does not fall to at least the set point / low offset temperature average (and the door is not opened during the last run period), then SERVICE will flash along with the error code (See Figure 3-18).

NOTE: To clear a flashing SERVICE and EC, the problem must be corrected, then switch the unit off then back on and/or press the Bell ON/OFF key for 15 seconds. Failure to clear an error code will cause SERVICE to display constant once Diagnostic Mode is initiated.

NOTE: If the unit is ever switched OFF then back ON, the compressor will not energize for at least 3 minutes. This 3 minute minimum OFF time is used to protect the compressor and its electricals.

NOTE: Prior to serial #2092137, SERVICE will flash if a compressor runs 100%, but no error codes will be logged.

Monitor Icemaker System and Display If Service is Needed (Starting with Serial #2092137)

The microprocessor observes the 115 Volts AC supplied to the icemaker water valve solenoid. If the solenoid is energized for more than 15 seconds, power to the icemaker system is disabled for 24 hours (See Figure 3-19), and an error code is logged (EC 30). If this happens five consecutive times, ICE and SERVICE on the LCD will flash and the ICE ON/OFF key will be disabled (See Figure 3-20).

NOTE: To clear the ICE and SERVICE error indicators, and reactivate the ICE ON/OFF key, the problem must be corrected, then the unit must be switched OFF and back ON, and the Alarm key must be pressed for 15 seconds to clear the Error Code.

NOTE: To allow ice to freeze fully and reduce effects of low water pressure, power to the icemaker system is interrupted for 45 minutes after each ice harvest. This can be bypassed for service purposes by switching the icemaker system OFF, then back ON using the ICE ON/OFF key.

NOTE: When in Sabbath Mode, the icemaker system is disabled. Sabbath Mode will be covered

NOTE: Prior to serial #2092137, ICE and SERVICE will flash if

UNIQUE ELECTRONIC CONTROL INPUT OPERATIONS

The following pages illustrate unique input operations performed at the control panel that you would not expect a customer to perform every day. The input operations described are: Temperature Unit Selection Mode, Sabbath Mode, Showroom Mode, Manual Compartment Disable Mode and Manual Freezer Evaporator Defrost.

Temperature Units Selection Mode (Selecting Degrees Fahrenheit or Degrees Celsius Display)

The electronic control is initially set to display temperature in Fahrenheit (°F) units of measure. Units of measure can be converted from °F to °C (Celsius), and/or back again. This operation is called Temperature Units Selection.

NOTE: Temperature Units Selection must be performed within the first minute after switching the unit ON.

To convert temperature units of measure from Fahrenheit (°F) to Celsius (°C) readings, press and hold the door ajar alarm bell ON/OFF key and the UNIT ON/OFF key simultaneously for 5 seconds, then release the keys (See Figure 3-21). “ °C “ will appear on the LCD indicating that temperatures will now be displayed in Celsius units of measure. To convert back to Fahrenheit units of measure, repeat the steps above (See Figure 3-22).

NOTE: Temperature Units Selection Mode will end 10 seconds after the last key stroke.

NOTE: Do not

press and hold the UNIT ON/OFF key first, that will simply switch the unit OFF.

TROUBLESHOOTING INPUT OPERATIONS

The following few pages explain troubleshooting input operations performed at the control panel. The input operations described are Diagnostic Mode, Manual Component Activation Mode and Temperature Log Recall.

Diagnostic Mode

Initiating Diagnostic Mode allows the Service Technician to observe real-time temperature readings from all thermistors without temperature averaging. If errors were registered by the thermistors or the defrost system, “Error Codes” will also be displayed during diagnostic mode.

To initiate Diagnostic Mode, the unit must be ON, then press and hold either

COLDER key, and press the UNIT ON/OFF key, then release both keys (See Figure 3-37). If no error codes are registered, the left display area will show real-time temperature of the thermistor, the right display area will show the thermistor location code, and all LCD indicators will illuminate. Pressing either

COLDER key or either WARMER key while in Diagnostic Mode will

toggle to the next or previous thermistor location, respectively. (See Figure 3-38, 3-39 and 3-40)

NOTE: If the COLDER and UNIT ON/OFF keys are pressed and held for 10 seconds, Manual Component Activation Mode will be initiated (this is covered later in the section).

NOTE: Diagnostic Mode will end 20 seconds after the last key stroke.

Press and Hold Desired COLDER Key and UNIT ON/OFF Key for 10 Seconds

Manual Component Activation Mode

Manual Component Activation Mode energizes a cooling system for 5 minutes. When activated, the chosen compartment’s compressor and evaporator fan are energized along with the condenser fan. While in Component Activation Mode, the evaporator temperatures for that compartment are displayed on the LCD. This mode also allows the Service Technician to check for proper voltage readings at the activated components without having to wait for the compartment to call for cooling.

To initiate Manual Component Activation Mode, the unit must be ON, then press and hold the desired compartment COLDER key and UNIT ON/OFF key for 10 seconds (See Figure 3-46). The evaporator temperature for that compartment will be displayed in left display area of the LCD and the right display area will show the thermistor location.

NOTE: If the COLDER and UNIT ON/OFF keys are pressed and held for less then 10 seconds, Diagnostic Mode will be initiated. This was covered earlier in the section.

NOTE: It is possible to toggle through the other temperature readings as in Diagnostic Mode, but in this case the temperature readings will last for 5 minutes rather than 20 seconds.

NOTE: The compressor overload could prevent the compressor from energizing.

NOTE: Manual Component Activation Mode will end 5 minutes after initiated. It is possible to end this 5 minute run

time and return to normal operation by switching the unit OFF then back ON. If this is done, note that the electronic control will observe a three minute minimum compressor OFF time when the unit is switched back ON. This is to protect the compressor and its electricals.

Press and hold for 10 seconds

Clearing Error Codes

If error codes are observed in diagnostic mode, a non-flashing

SERVICE indicator will appear on the LCD when Diagnostic Mode ends, indicating error codes are still logged (See Figure 3-44). To clear a non-flashing SERVICE indicator and the error codes, the problem must be corrected and the unit must be ON. Then, the Bell ON/OFF key must be pressed and held for fifteen seconds. The control will emit a short “beep” when the SERVICE indicator and error codes are cleared. (See Figure 3-45)

Temperature Log Recall Mode

The electronic control system is equipped with a temperature history data storage system. This system logs/stores the average temperature of each individual thermistor every two hours, along with any event indicators (explained later in this section), that may have occurred. These two-hour periods are referred to as “indexes”. Up to 168 indexes can be stored for each compartment, making it possible to observe the preceding fourteen days of the unit’s temperature history (each index equals 2 hour temperature average; 2 hours X 168 indexes = 14 days). After 168 indexes are stored, each new index will bump the oldest index. Index number “1” being the most recent two-hour temperature average and index number “168” being the oldest. Accessing this temperature history data so it can be viewed on the LCD is accomplished by initiating Temperature Log Recall Mode.

There are two ways to initiate Temperature Log Recall Mode. One allows viewing of compartment temperature history only (see below), the other allows viewing of compartment temperature history and evaporator temperature history (see following page).

Initiate Temperature Log Recall Mode To View Compartment Temperature History Only - Begin with the unit ON. Now, press and hold the desired compartment WARMER key, then press the UNIT ON/OFF key, then release both keys (See Figure 3-47). The left display area on the LCD will show average compartment thermistor temperature and in the right display area will be the index number. The first index number will be “1”, indicating the most recent two-hour temperature average. The right display area will also flash the thermistor location code at 3 second intervals (See Figure 3-48).

should the control board be

replaced.

NOTE: If Manual Compartment Disable Mode has been activated during any of the 168 indexes, average temperatures will continue to be logged. No event indicator will appear with these temperatures.

NOTE: If the unit was in Showroom Mode during any of the 168 indexes, average temperatures will continue to be logged. No event indicator will appear with these temperatures.

NOTE: If the unit was switched OFF by pressing the UNIT ON/OFF key during any of the 168 indexes and there was still 115V AC supplied to the control board, the average temperatures will continue to be logged. This means temperatures would be expected to rise and the SERVICE indicator would be present in all indexes in which the unit was switched OFF.

NOTE: Temperature Log Recall Mode will end 20 seconds after the last key stroke.

Temperature Log Index Chart

NOTE : The chart below applies to the hours in which the control has power. Temperature history data will only be stored when the control has 115V AC supplied to it. If power to the unit is interrupted by switching the unit OFF at the UNIT ON/OFF key or due to a power failure, the average temperatures for that time period are stored with the event indicator. The temperature history data is stored in a non-volatile memory, so the data is not erased if power is interrupted.

HFC-134a REFRIGERANT SERVICE INFORMATION

The 600-2 Series sealed systems contain HFC-134a refrigerant. This section provides general rules for working with 134a, and procedures to be followed while servicing the sealed system. This is followed by diagrams illustrating sealed system operation, then model-specific refrigerant flow diagrams.

134a refrigerant requires Synthetic Ester oil in the compressor, and does not tolerate contamination from other refrigerants, moisture, petroleum-based lubricants, silicone lubricants, cleaning compounds, rust inhibitors, leak detection dyes, or any other type of additive.

General Rules for Working with 134a Refrigerant

• Use equipment dedicated to 134a sealed system service only.

• Use only 134a refrigerant for back-flushing and sweep charging.

• Always replace the filter-drier when servicing the sealed system.

• The filter-drier must be cut from the sealed system. Never un-braze the drier as the heat will drive moisture back into the sealed system.

• Do not leave sealed system nor replacement compressor open to the atmosphere for more than 10 minutes.

• When the rubber plugs are pulled from the service compressor, a release of pressure should be heard. If no release of pressure is heard, do not use the compressor.

• Use ONLY virgin 134a refrigerant when recharging the sealed system.

SEALED SYSTEM OPERATION

The following six diagrams illustrate a basic sealed system. The components are listed in order of refrigerant flow, with an explanation of their fundamental role as part of a sealed system. NOTE: These illustrations do not

represent any specific 600-2 Series sealed system.

Compressor (Figure 4-1)

The compressor creates a high side and low side pressure difference in the sealed system by compressing the refrigerant gas, thus raising the pressure and temperature. The compressor pushes this high-pressure/highheat gas through the door gasket seat heater loop to prevent sweating (on most units the gas also travels through drain pan heater tubing to help evaporate water in the drain pan). The high-pressure/high-heat gas then travels to the condenser.

Condenser (Figure 4-2)

The high-pressure/high-heat gas travels through the condenser, where the heat is dissipated by cooler air being drawn over the condenser tubing by the condenser fan. This changes the gas into a high-pressure/warm liquid that then enters the high-side filter-drier.

High-Side Filter-Drier (Figure 4-3)

The high-pressure/warm liquid travels through the highside filter-drier, which removes moisture from the refrigerant before it enters the capillary tube.

Capillary Tube (Part of Heat Exchanger) (Figure 4-4)

The high-pressure/warm liquid refrigerant travels through the long skinny capillary tube which is attached to the suction line. (These two tubes soldered together create the heat exchanger.) As the high-pressure/warm liquid refrigerant travels through the capillary tube it gives up heat to the cool refrigerant gas traveling through the suction line and the pressure drops, so it is a lowpressure/cool liquid before it enters the evaporator.

Evaporator (Figure 4-5)

As the low-pressure/cool liquid refrigerant enters the evaporator, it vaporizes. This is caused by a dramatic pressure change which occurs when the refrigerant enters the larger diameter evaporator tubing from the smaller diameter capillary tubing. This vapor travels through the evaporator absorbing heat from the compartment, gradually converting it to a cool gas. This cool gas then enters the suction line.

Suction Line (& Heat Exchanger) (Figure 4-6)

The cool gas travels through the suction line which is attached to the capillary tube. (As mentioned earlier, these two tubes soldered together create the heat exchanger.) As this cool refrigerant gas travels through the suction line it absorbs heat from the warm liquid refrigerant traveling through the capillary tube, making it a luke warm gas. The lukewarm refrigerant gas returns to the compressor where the process begins again.

ICEMAKER SYSTEM INFORMATION

All 600-2 series units utilize a MidSouth icemaker. Icemaker operation is not complex, but its components and operation cycle should be understood by a Service Technician in order to make proper diagnosis.

TO AVOID ELECTRIC SHOCK, ALWAYS DISCONNECT ELECTRICAL POWER TO UNIT WHEN SERVICING ICEMAKER.

NOTE: The ICE ON/OFF key at the control panel activates the icemaker system. If “ICE” is not displayed on the LCD, the icemaker system is off.

NOTE: To allow ice to freeze fully and reduce effects of low water pressure, the electronic control disables the icemaker system for 45 minutes after each ice harvest.

NOTE: The ice bucket in models 601F-2, 611-2, 611G2, 650-2 and 650G-2, have a tab at left rear corner that activates a switch when the ice bucket is in place. The ice bucket in the models 685-2 and 695-2 also activates a switch when in place. If the ice bucket is not in proper position on any model, ice production will stop.

NOTE: The defrost relay on the control board controls the fill tube heater.

ICEMAKER COMPONENTS

Following are descriptions that explain the function of each icemaker component. The components are diagramed in Figure 6-1 on the next page.

Support - The support is the housing around the electrical components and wire connections. The support is attached to the ice mold.

Mounting Plate - The drive motor, holding switch, water valve solenoid switch, timing gear, timing cam and water fill adjusting screw are attached to the metal mounting plate. The mounting plate is then attached to the support.

Drive Motor - 115 volts AC supplied to the drive motor causes the motor to operate. The motor has a single output shaft with a small gear. The motor gear drives/spins the timing gear.

Timing Gear - The timing gear is driven/spun by the drive motor gear and is attached to the timing cam.

Timing Cam - The timing cam is attached to the timing gear and the ice ejector is inserted into the center of the timing cam. As the timing cam rotates, high and low spots on the cam operate the water valve solenoid switch and the holding switch. The timing cam also moves the lever arm side to side and rotates the ice ejector.

Ice Mold - The ice mold is where the eight crescent shaped ice cubes are formed.

Mold Heater - The mold heater uses 175 watts to thaw the ice free from the mold.

Ice Ejector - The drive end of the ice ejector is “D” shaped to fit into the “D” shaped hole in the timing cam. It has eight blades which rotate and sweep the ice from the mold cavities during the ejection phase of the cycle.

Ice Stripper - The stripper is attached to the dumping side of the mold, serving as a decorative side cover and it also prevents ice from falling back into the mold.

Bearing / Inlet - The bearing / inlet is attached to the ice mold, opposite the support. Water enters the bearing / inlet and is directed to the ice mold. The bearing/inlet also supports the ice ejector at the end opposite the timing cam.

Thermostat - The thermostat is a single-pole, singlethrow, bi-metal switch. At 15°F/± 3°F it closes, starting the ice ejection phase.

Thermal-Mastic - A substance similar in appearance to grease that is applied between the thermostat and the ice mold. Its purpose is to increase thermal conductivity between the mold and the thermostat.

Lever Arm and Shut-off Arm - The lever arm is moved side to side by two revolutions of the timing cam. As it moves, it raises and lowers the shut-off arm and operates the shut-off switch to control the quantity of ice production. If the shut-off arm comes to rest on top of the ice in the storage bin during either revolution, the shut-off switch will remain open, stopping ice production at the end of that revolution.

Water Valve Solenoid Switch - A single-pole, doublethrow type switch that allows electricity to the water valve solenoid, opening the valve, during the fill cycle.

Holding Switch - A single-pole, double-throw type switch that assures completion of a revolution once the icemaker has been energized.

Shut-off Switch - A single-pole, double-throw type switch that stops ice production when the ice bin is full.

TCO (Thermal Cut Out) - The TCO is thermal protection device in the wire harness that would open in the event of mechanical failure, thus protecting against over heating. (The TCO is not shown in diagram.)

End of Ice making Cycle (See Figure 6-11)

• The water valve solenoid switch is tripped by the timing cam back to “normally open” ending the water fill.

• The timing cam trips the holding switch to “normally close,” which ends the second revolution.

• The thermostat is still open, so it does not start the drive motor.

• If the shut-off arm has come to rest on top of the ice in the storage bin (as illustrated), the shut-off switch remains in the “normally closed” position. This interrupts power from reaching the thermostat, until sufficient ice has been removed from the storage bin allowing the shut-off arm to lower.

NOTE: To allow ice to freeze fully and reduce effects of low water pressure, the electronic control system disables the icemaker system for 45 minutes after each ice harvest.

Figure 6-12. Stopping Icemaker

MANUALLY STOPPING ICE PRODUCTION

Ice production can be manually stopped four ways:

1. Press the ICE ON/OFF key on the control panel so that “ICE” is not displayed on the LCD.

MANUALLY STARTING THE ICEMAKER

NOTE: To allow ice to freeze fully and reduce effects of low water pressure, the electronic control disables the icemaker system for 45 minutes after each ice harvest. To bypass this 45 minute dwell for service purposes, press the the ICE ON/OFF key at the control panel.

Manual S

art Procedure:

1. Pry the icemaker front cover from the support using a flat-blade screwdriver or coin.

2. With a flat-blade screwdriver, turn the drive gear counterclockwise until the holding switch is activated, completing the circuit to the drive motor (this will be about a 1/8 turn). (See Figure 6-13) The icemaker will then complete its cycle automatically.

NOTE: If after 1/4 turn the icemaker is not running on its own, it may be in the 45 minute dwell period or there is an electrical or mechanical problem.

ADJUSTING ICEMAKER WATER FILL LEVEL

Proper water fill level for a MidSouth icemaker is 100 110 cc’s (3.5 - 3.75 oz). If the fill level is checked and needs to be adjusted, turn the water fill adjusting screw clockwise to reduce fill level, or counterclockwise to increase fill level. One full turn of the screw equals 15 cc’s. (See Figure 6-14)

NOTE: Always check fill level before making any adjustments of the water fill adjusting screw.
