Important Product Information

WARNING

Precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy or electrical shock, disconnect power to oven.

Do not operate or allow oven to be operated with door open. Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary:

• Interlock operation

• Proper door closing

• Seal and sealing surfaces (arcing, wear , and other damage)

• Damage to or loosening of hinges, and latches

• Evidence of dropping or abuse

Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, waveguide or transmission line, and cavity for proper alignment, integrity , and connections. Any failed or misadjusted components in the interlock, monitor, door seal, microwave generation, and transmission systems shall be repaired, replaced or adjusted by procedures described in this manual before oven is released to the consumer . Check microwave leakage to verify compliance with the federal performance standard should be performed on each oven prior to releasing to the consumer .

WIRING

Good service practice is to never route wiring over terminals and/or sharp edges. This applies to any wiring without regard to the circuit voltage. Wire insulation material and thickness is designed and regulated for electrical spacing purpose only , but cannot always be relied upon because of possible cuts and/or abrasions, which can occur during servicing.

WARNING

T o avoid risk of electrical shock, personal injury or death; make sure to follow grounding instructions.

Grounding Instructions

WARNING

Do not remove grounding prong when installing grounded appliance in a home or business that does not have three wire grounding receptacle. Under no condition is grounding prong to be cut off or removed. It is the personal responsibility of the consumer to contact a qualified electrician and have properly grounded three prong wall receptacle installed in accordance with appropriate local electrical codes.

Should a two prong adapter plug be required temporarily it is the personal responsibility of the consumer to have it replaced with a properly polarizied and grounded three prong receptacle or the two prong adapter properly grounded by a qualified electrician in accordance with appropriate electrical codes.

Servicing of Grounded Products

The standard accepted color coding for grounding wires is GREEN or GREEN WITH YELLOW STRIPE. These ground leads are NOT to be used as current carrying conductors. It is extremely important that the technician replace any and all grounds prior to completion of the service call. Under no condition should ground wire be left off, which can cause a potential hazard to technicians and consumer .

Important Safety Information

CAUTION

Do not become exposed to radiation from the microwave generator or other parts conducting microwave energy .

Basic design of this microwave oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing microwave ovens to maintain this safety . These are as follows:

1. Always operate unit from an adequately grounded outlet. Do not operate on a two-wire extension cord.

2. Before servicing unit (if unit is operable) perform microwave leakage test.

3. Oven should never be operated if door does not fit properly against seal, hinge/hinge bearings are damaged or broken; choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check choke area to ensure that this area is clean and free of all foreign matter. If any above problems occur take the following steps:

• Tell the user not to operate the oven.

• Contact Amana immediately .

4. If oven operates with door open and produces microwave energy , take the following steps:

• Tell the user not to operate the oven.

• Contact Amana immediately .

5. Always have oven disconnected when outer case is removed except when making "live" tests called for in the service manual. Do not reach into equipment area while unit is energized. Make all connections for the test and check them for tightness before plugging cord into outlet.

6. Always ground capacitors on magnetron filter box and H.V . capacitor with an insulated-handle screwdriver before working in high voltage area of equipment compartment. Some types of failures will leave a charge in capacitors and the discharge could cause a reflex action which could make you injure yourself.

7. In the area of the transformer, capacitor , diode, and magnetron there is HIGH VOL T AGE. When unit is operating, keep area clean and free of anything which could possibly cause an arc or ground, etc.

8. DO NOT for any reason defeat interlock switches, there is no valid reason for this action at any time; nor will it be condoned by Amana.

9. Microwave ovens should never be operated with:

• Any components removed and/or bypassed

• Any of the safety interlocks are found to be defective

• Any of the seal surfaces which are failing, missing or damaged

10.To ensure that unit does not emit excessive microwave leakage and to meet Department of Health and Human Services guidelines check oven for microwave leakage using Narda Model 81 10B or Holaday HI1501, HI1510, HI1710 leakage monitor as outlined in instructions. Maximum leakage level allowed is 4mw/cm

1 1.If servicer encounters an emission reading over

4mw/cm2, servicer is to cease repair and contact Amana Service Department immediately for further direction. Amana will contact the proper Government Agency upon verification of test results.

Product Information

Antenna

Distributes microwave energy throughout the cavity.

Blower/Fan Assembly

Circulates cooling air throughout the microwave oven compartment and cavity .

Splatter Shield

Covers and protects the antenna assembly .

Door Interlock and Monitoring Switch

NOTE: When the line fuse is blown the Interlock Switch

Assembly must be replaced.

Interlock switch (assembly) mounts behind oven cavity front bulkhead. It is actuated by door hook and guide attached to the door .

Monitoring switch (contacts 7 and 8) is actuated by the door guide.

The secondary interlock switch (contacts 2 and 3) and primary interlock switch (contacts 4 and 5) are actuated by the door hook.

The secondary interlock switch is in series with the interlock monitoring switch in the monitor circuit.

If a malfunction occurs in the secondary interlock when door opens, current will flow through the monitor switch causing the oven fuse to open.

If a faulty door interlock switch has allowed current through the monitor switch, the switch assembly must be replaced (see interlock switch testing) before replacing fuse.

Transformer High Voltage

High voltage transformer is used in this unit, which supplies high voltage A.C. for operation of the magnetron tube.

High Voltage Capacitor

Doubles the A.C. output voltage from the high voltage transformer.

High V olt age Diode (Rectifier)

Is connected at the output side of the high voltage capacitor. It changes voltage from A.C. to D.C. It passes current in one direction and blocks it in the other. Also called a rectifier.

Magnetron

With filament voltage and high D.C. voltage from the output of the H.V . capacitor, diode junction the magnetron will put out an electomagnetic radio frequency of 2450 MHz to heat the food load in the oven.

Thermal Protectors

At a predetermined temperature the thermal cut-outs will open or close. The oven will indicate an error code in the display , initiate cooling fan operation, or prevent the generation of microwave energy .

• Magnetron thermal cut-out is mounted directly on the body of the magnetron.

• Oven cavity thermal cutout is mounted inside the exhaust duct.

DANGER

To avoid severe personal injury or death avoid contacting any high voltage parts. The capacitors are at high voltage (4000 volt) potential and it is extremely important that they be grounded before handling.

Grounding Instructions

NOTE: Do not under any circumstances cut or remove

grounding prong from the plug or bend power prongs to fit receptacle other than one shown for your equipment. Such abuse of the plug can result in electrical shock or overheating.

WARNING

Improper use of grounding plug can result in a risk of electrical shock or death.

This equipment MUST be grounded. In the event of an electrical short circuit, grounding reduces risk of electric shock by providing an escape wire for electric current. This oven is equipped with a cord having grounding wire with a grounding plug. Plug must be plugged into an outlet that is properly installed and grounded. DO NOT use a two-prong adapter .

Consult a qualified electrician or servicer if grounding instructions are not completely understood or if doubt exists as to whether the equipment is properly grounded.

Do not use an extension cord. If product power cord is too short, have a qualified electrician install an appropriate receptacle. This equipment should be plugged into a separate 60 Hz circuit with the appropriate electrical rating label. When the oven is on a circuit with other equipment, an increase in cooking times may be required and fuses can be blown.

Radio Interference

Microwave operation may cause interference to radio, television or a similar oven. Reduce or eliminate interference by doing the following:

• Clean door and sealing surfaces of oven according to instructions in Care and Cleaning section.

• Place radio, television, etc. as far as possible from oven.

• Use a properly installed antenna on radio, television, etc. to obtain stronger signal reception.

Oven Placement

• Do not install oven next to or above source of heat, such as pizza oven or deep fat fryer. This could cause microwave oven to operate improperly and could shorten life of electrical parts.

• Do not block or obstruct oven filter . Allow access for cleaning.

• Install oven on level countertop surface.

• Place warning label in a conspicuous place close to microwave oven.

• Outlet should be located so that plug is accessible when oven is in place.

Unpacking Oven

• Inspect oven for damage such as dents in door or inside oven cavity .

• Report any dents or breakage to source of purchase immediately.

• Do not attempt to use oven if damaged.

• Remove all materials from oven interior.

• If oven has been stored in extremely cold area, wait a few hours before connecting power.

A—Allow at least 7 " (17.8 cm) of clearance around

top and sides of oven. Proper air flow around oven cools electrical components. With restricted air flow, oven may not operate properly and life of electrical parts is reduced.

Power Testing Procedure

To avoid risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitor before servicing, unless testing requires power.

WARNING

Power Test (Traditional Test Method)

Test equipment required is Amana power test kit R0157397 (Fahrenheit), or Menumaster power test kit M95D5 (Celsius).

1. Fill the plastic container to the 1000 ml. line with cool tap water.

2. Using the thermometer; stir the water, measure, and record the water temperature.

Initial water temperature should be approximately 60°F(16°C).

3. Place container on the center of the oven shelf and heat the water for

33 seconds for ovens with more than 1550 watts or 63 seconds for ovens with less than 1550 watts.

NOTE: Use a watch second hand, not the oven timer.

4. Stir the water, measure and record the temperature of the water after heating time is complete.

5. Subtract the starting water temperature (Step 2), from the ending water temperature (Step 4) to obtain the temperature rise (∆T).

6. See the Traditional Power Test Temperature Chart below.

NOTES: •The IEC-705 test method requires precision measurements and equipment. It is not practical to perform

the IEC test in the field. To convert the traditional power test results to the approximate IEC-705 rating, take the traditional power test results and add 150 watts per magnetron for the unit being tested.

Example: 1400  watts output using the traditional power test for model RC17S

 watts (2 magnetrons X 150 watts)

+ 300

1700  Approximate IEC-705 results

•Always perform power test three times for accuracy, changing the water after each test is performed.

•Variation or errors in the test procedure will cause a variance in the temperature rise. Additional power

tests should be made if temperature rise appears marginal.

•Low line voltage will cause lower temperature rise.

Microwave Leakage Test

WARNING

Measurement With the Outer Case Removed

Check for radiation leakage after servicing. Should the leakage be more than 4mW/cm2 inform Amana immediately . After repairing or replacing any radiation safety device, keep a written record for future reference, as required by D.H.H.S. and HEW regulations. This requirement must be strictly observed. In addition, the leakage reading must be recorded on the service repair ticket while at the customer’s location.

Equipment

• Electromagnetic radiation monitor

• 600 cc glass beaker

Procedure For Measuring Radiation Leakage

Note before measuring -

• Do not exceed meter full scale deflection. Leak monitor should initially be set to the highest scale.

• To prevent false readings the test probe should be held by the grip portion of the handle only .

• The scan speed is equal to one inch per antenna revolution or one inch per second if antenna speed is unknown.

• Areas to be checked are all door seal areas and any venting parts.

• Leakage with the outer panel removed, 4mW/cm2 or less.

• Leakage for fully assembled oven with door normally closed, 4mW/cm2 or less.

• Leakage for a fully assembly oven (before the latch switch (primary) is interrupted) while pulling the door, 4mW/cm2 or less.

DANGER

To avoid risk of personal injury or death avoid contacting any high voltage components.

Whenever you replace the magnetron, measure for radiation leakage before the outer case is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring around the magnetron.

Measurement With a Fully Assembled Oven

After all components, including the outer panel are fully assembled, measure for radiation leakage around the door periphery , the door viewing window , the exhaust opening, and air inlet openings.

Record Keeping and Notification After Measurement

1. After any adjustment or repair to a microwave oven, a leakage reading must be taken. Record this leakage reading on the repair ticket even if it is zero.

2. A copy of the repair ticket and the microwave leakage reading should be kept by the repair facility .

1. Open the oven door and verify that there is only one rack in place on the bottom rack hooks.

2 . Pour 275 ± 15 cc (9 oz ± 1/2 oz) of 20 ± 5°C. (68±

9°F.) water in a glass beaker which is graduated to 600 cc and place the beaker in the center of rack.

3. Set the radiation monitor to 2450 MHz and use it following the manufacturer’s recommended test procedure to assure correct results.

4. While measuring the leakage, always use the two inch (5 cm) spacer supplied with the probe.

5. Press the start pad or turn on the timer and with the magnetron oscillating, measure the leakage by holding the probe perpendicular to the surface being measured.

Display and Features

Single Pad Programming

This feature enables each numbered pad to be

programmed for a specific use, such as cooking a certain number of potatoes or defrosting and then cooking vegetables or other frozen foods. To use this feature, simply program the pad to the desired length of time and power level. To use this feature, press the pad once and the microwave will begin cooking.

Double Pad Programming

This feature enables 100 programmed entries to be made. Each entry will be assigned a double digit number, for example 01, 05, or 20. When using the double pad programming, two pads must be pressed to start the cooking cycle.

Manual Time Entry

In addition to programmable pads, this microwave also accepts specific time entry by using the TIME ENTRY pad. Using manual time entry does not affect the programmed buttons.

Quantity Pad

The quantity pad increases a preset cooking time by a percentage

of the original cooking time. The user specifies the percentage and it can be changed for individual cooking sequences. Quantity can be increased up to 8 times. Once pressed, QTY will display with the number times the cooking time will be extended. This feature is very useful for cooking multiple servings of foods such as potatoes or slices of pizza.

Stage Cooking

Stage cooking is a cooking sequence with specific power stage

changes. The user can program up to four different power level changes and the specific amount of cooking time at each power level. Each power level/cooking time combination is known as a stage. Up to four stages can be programmed.

Start Pad

The start pad is used to begin a manual time entry cooking cycle.

STOP/RESET pad

The STOP/RESET pad stops a

cooking sequence in progress, clears out any remaining time, and also ends a programming or user option cycle. When the STOP/RESET pad is used to end a programming or option change, the changes are discarded.

Mid-Cycle Cooking Pause

The cooking pause is a feature unique to this series of microwaves. This pause enables extra ingredients to be added, cooking progress to be checked, or for food to sit a necessary amount of time between cooking time or power settings. To utilize Cooking Pause, follow programming sequences for programmable pads.

OP:--

Options such as beep volume, and the number of programmable pads can be changed. To change different options, see

Equipment Set-Up and Close Procedures

Introduction

WARNING

To avoid risk of electrical shock, severe personal injury or death, do not remove outer case at any time. Only authorized servicer should remove outer case.

This Amana oven uses microwave technology to restore heat that is lost during the assembly of menu items. This unit may also be used in preparation of specific ingredients or components of a menu item.

Each unit is equipped with pre-programmed control panel allowing the crew person to begin the heating process based on menu item and quantity .

Hazard Communication Standard—The procedure(s) in this chapter may include the use of chemical products. These chemical products will be highlighted with bold face letters followed by abbreviation (HCS). See Hazard Communication Standard (HCS) Manual for appropriate Material Safety Data Sheets (MSDS).

Do Not Operate the Unit When Empty

When operating oven, be sure there is absorbing material (food, water) inside oven. Insufficient or improper food loads may cause magnetron(s) to overheat. Using metal containers may also cause the magnetron to overheat. When magnetrons do overheat, the thermal switch will turn the oven off to allow the magnetron to cool. Several minutes will elapse before the switch resets and allows the oven to operate.

CAUTION

To avoid risk of property damage, do not use abrasive cleaners or cleaners containint ammonia. They might damage the finish. Never pour water into the bottom of oven.

Do Not Put Excessive Weight on Door

The oven door is NOT designed to hold excessive weight. Additional weight placed on door can cause it to become misaligned. This will result in improper oven operation.

Be sure to “wring” sponge or cloth to remove excess water before wiping out unit. Water pressure type cleaning systems should not be used to clean oven interior or exterior. If stubborn splatters exist on walls, one cup of tap water can be boiled in the oven for 1 - 2 minutes. Use your Amana wattage beaker for this procedure. Steam from boiling water will help loosen splatters.

2. Wipe exterior with clean sanitized towel soaked in McD Sanitizer (HCS). Allow oven to air dry.

3. Close door after cleaning, and press appropriate menu pad for breakfast category . Unit is ready for OPEN.
