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. Products should be serviced only by a qualified service technician who is familiar with the safety procedures required in the repair and who is equipped with the proper tools, parts, testing instruments and the appropriate service information. IT IS THE TECHNICIANS RESPONSIBLITY TO REVIEW ALL APPROPRIATE SERVICE INFORMATION BEFORE BEGINNING REPAIRS. ! WARNING To avoid risk of severe personal injury or death, disconnect power before working/servicing on appliance to avoid electrical shock. To locate an authorized servicer please contact: ComServ Support Center Web Site WWW.ACPSOLUTIONS.COM ....................... Telephone Number 1-866-426-2621 or 319-368-8195 E-Mail: [email protected] Recognize Safety Symbols, Words, and Labels ! DANGER DANGER— Immediate hazards which WILL result in severe personal injury or death. ! WARNING WARNING— Hazards or unsafe practices which COULD result in severe personal injury or death. ! CAUTION CAUTION— Hazards or unsafe practices which COULD result in minor personal injury, product or property damage. 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. Do not for any reason defeat the interlock switches there is not valid reason for this action at any time; nor will it be condoned by ACP. 2. Before servicing the unit (if unit is operable) perform the microwave leakage test. 9. IMPORTANT: Before returning a unit to a customer, be sure to check for proper switch interlock action. 3. The oven should never be operated if the door does not fit properly against the seal, the hinges or hinge bearings are damaged or broken; the choke is damaged, (pieces missing, etc.); or any other visible damage can be noted. Check the choke area to ensure that this area is clean and free of all foreign matter. 4. If the oven operates with the door open and produces microwave energy, take the following steps: A. Tell the user not to operate the oven. B. Contact ACP ComServ immediately. 5. Always have the oven disconnected when the outer case is removed except when making the "live" tests called for in the Service Manual. Do not reach into the equipment area while the unit is energized. Make all connections for the test and check them for tightness before plugging the cord into the outlet. 6. Always ground the capacitors on the magnetron filter box with an insulated-handle screwdriver before working in the high voltage area of the equipment compartment. Some types of failures will leave a charge in these capacitors and the discharge could cause a reflex action which could make you injure yourself. 7. Always remember that in the area of the transformer there is HIGH VOLTAGE. When the unit is operating keep this area clear and free of anything which could possibly cause an arc or ground, etc. 10. The Microwave Oven should never be operated with any components removed and/or bypassed or when any of the safety interlocks are found to be defective, or when any of the seal surfaces are defective, missing, or damaged. 11. All microwave ovens meet all requirements of the radiation control for Health and Safety Act of 1968. Due to measurement uncertainties, the maximum leakage for the field will be 4mw/cm2. 12. To ensure that the unit does not emit excessive microwave leakage and to meet the Department of Health and Human Services guidelines, check the oven for microwave leakage using a microwave oven leakage meter that complies with US Government CDRH / FDA / DHHS requirements and or any other local government requirements. The maximum leakage level allowed by ACP 2 is 4mw/cm . 13. If servicer encounters an emission reading over 4mw/cm 2, the servicer is to cease repair and contact the ACP ComServ Department immediately for further direction. ACP will contact the proper Government Agency upon verification of the test results. ! 6 * ? WARNING ?

Connect an ohm-meter to wire harness (as shown in figure 1, to verify switch activation). Note: The switch assembly should activate when the door gap is approximately 1/4 inch (6mm). Switch Adjustment: 1. Loosen mounting screws. 2. Slide adjustment lever for proper switch activation. 3. Tighten mounting screws. 4. Preheat oven to set temperature and verify switch adjustment settings and function. Note: To ensure proper switch adjustment, the switch mounting MUST be tightened after each adjustment prior to testing the door alignment. Replacement Removal: 1. Remove switch assembly mounting screw. 2. Push switch assembly 1/2 inch (13mm) towards back of oven. 3. Twist mounting leg towards oven cavity to release mounting tab. 4. Push assembly towards back of oven to remove. Note: New replacement switch assembly has been adjusted at the factory, no adjustment should be necessary.

Radiant Convection RTD RTD % s r % ) & s & ! % 2YHQ3HUIRUPDQFH7HVW 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. Test equipment required: x x 1000 ml test container and thermometer (ACP Power Test Bowl part # 12018801). Digital watch / watch with a second hand for use on ovens with electromechanical timers. Important Notes: x x x Low line voltage will cause low temperature rise / power output. Ovens must be on a dedicated circuit, properly grounded, and polarized. Other equipment on the same circuit may cause a low temperature rise / power output. This test and results are not a true IEC705 test procedures and are only intended to provide servicers with an easy means of determining if the microwave oven cooking output is correct. Procedure 1. Fill the test container to the 1000 ml line with cool tap water. NOTE: Water temperature should be approximately 60qF / 16qC 2. Using the thermometer, stir water for five to ten seconds; measure, and record the temperature (T1). 3. Place test container of water in the center of oven cavity and close door. 4. Heat the water for a 33-second full power cycle. NOTE: Use a digital watch or a watch with a second hand for ovens with electromechanical timers. 5. At end of the cycle, remove test container. Using the thermometer, stir water for five to ten seconds and record temperature (T2). 6. Subtract the starting water temperature (T1), from the ending water temperature (T2) to obtain the temperature rise (¨T). 7. If the temperature rise (¨T) meets or exceeds the minimum, the test is complete. If the temperature rise (¨T) fails to meet the minimum temperature rise, test the line voltage to verify it is correct. Then repeat steps 1-6 making sure to change the water. If the temperature rise (¨T) fails to meet the minimum temperature rise again the oven will require service.
