Important Information Important Notices for Servicers and Consumers ACP will not be responsible for personal injury or property damage from improper service procedures. Pride and workmanship go into every product to provide our customers with quality products. It is possible, however, that during its lifetime a product may require service.
Important Safety Information ! WARNING Read the following information to avoid possible exposure to microwave radiation: The basic design of the Microwave Oven makes it an inherently safe device to both use and service. However, there are some precautions which should be followed when servicing the microwave to maintain this safety. These are as follows: 1. Always operate the unit from an adequately grounded outlet. Do not operate on a two-wire extension cord. 8.

Disassembly Control Panel Removal 1. 2. 3. 4. Disconnect power to oven and remove outer case. Disconnect and label wires from controller/timer. Open oven door. Remove screw securing top of control panel to cavity. Lift control panel up and out to release tabs. Disconnecting Wire Terminals All wire terminals are locking-type terminals. Proceed as follows to disconnect wire terminals: Insulated terminals: Grasp insulator pod and pull back. DO NOT PULL ON WIRE.
6 Performance Testing Procedures 17 2011 RFS Training Manual.
Performance Testing Procedures ! WARNING To avoid risk of electrical shock, personal injury or death, disconnect power to oven and discharge capacitor before servicing, unless testing requires it. All Amana and Menumaster microwave oven power outputs are rated using the IEC705 standards. Using the IEC705 test method requires precision measurements and equipment that is not practical to be performed in the field. Using the test shown below will indicate if the oven performance is satisfactory.
7 Component Testing Procedures 19 2011 RFS Training Manual.

8 Troubleshooting 24 2011 RFS Training Manual.
Troubleshooting WHEN YOU GET A COMPLAINT FROM YOUR CUSTOMER, EVALUATE THE COMPLAINT CAREFULLY. IF THE FOLLOWING SYMPTOMS APPLY, PLEASE INSTRUCT THE CUSTOMER IN THE PROPER USE OF THE MICROWAVE OVEN. THIS CAN ELIMINATE AN UNNECESSARY SERVICE CALL. 1. Check grounding before checking for trouble. 2. Be careful of the high voltage circuit. 3. Discharge the high voltage capacitor. 4.
Troubleshooting Trouble 1: The following visual conditions indicate a probable failed control circuit. 1. Incomplete segments. Z Segment missing. Z Partial segment missing. Z Digit \ 7 % ( (Note: Slight \ 7 % ( is normal.) 2. ) *% % ! 7 3. A distinct change in the brightness of one or more numbers in display. 4. One or more digits in the display are not lighting. 5.

Troubleshooting Trouble 2: Oven does not operate at all, Display window does not display any (*% U ) * ) CONDITION 1. Fuse blows. CHECK Check continuity of monitor switch (with door closed). RESULT Continuity. CAUSE REMEDY Malfunction of the monitor switch. Replace fuse, interlock assembly Shorted contact at the primary switch. Replace fuse, interlock assembly No continuity. Replace fuse Check continuity of primary switch (with door opened). Continuity.
Troubleshooting Trouble 3: Display shows all (*% U !* 3 ) % 7 ( 4, ) % ) % (% % ) TART ) * , ) CONDITION 1.Setting time does not count down when touching START pad. 2. Blower motor or oven lamp do not turn on. CHECK RESULT CAUSE REMEDY Defective secondary switch. Replace secondary switch. Check continuity of secondary switch (with door closed). No continuity. Check the connection between CN1 connector and PCB assembly.
Troubleshooting TROUBLE 5: No microwave oscillation even though oven lamp and blower motor run. (Display operates properly) CONDITION No microwave oscillation. CHECK Disconnect the wire leads from relay 3 and check continuity of relay 3 (Operate the unit) Check high voltage transformer RESULT No continuity. CAUSE REMEDY Defective PCB assembly Replace PCB assembly Defective high voltage transformer. Replace high voltage transformer. Defective high voltage capacitor.
