In the interest of user-safety the oven should be restored to its original condition and only parts identical to those specified should
be used.
WARNING TO SERVICE PERSONNEL: Microwave ovens contain circuitry capable of producing very high voltage and
current. Contact with the following parts may result in a severe, possibly fatal, electrical shock. (Inverter unit that includes
High Voltage Capacitor, High Voltage Power Transformer, High Voltage Rectifier and Heat sink etc., and Magnetron, High
Voltage Harness etc..)

  • Page 2: Precautions To Be Observed Before And During Servicing To Avoid Possible Exposure To Excessive Microwave Energy

    Before servicing an operative unit, perform a microwave emission check as per the Microwave Measure- ment Procedure outlined in this service manual. If microwave emissions level is in excess of the specified limit, contact Viking Service immediately @ 1-888-845-4641. If the unit operates with the door open, service person should (1) tell the user not to operate the oven and (2) contact VIKING, plus the Department Of Health, Canada and/or the Food and Drug Administration's Center for Devices and Radiological Health immediately.

    MICROWAVE MEASUREMENT PROCEDURE (USA) A. Requirements: 1) Microwave leakage limit (Power density limit): The power density of microwave radiation emitted by a microwave oven should not exceed 1mW/cm at any point 5cm or more from the external surface of the oven, measured prior to acquisition by a purchaser, and thereafter (through the useful life of the oven), 5 mW/cm at any point 5cm or more from the external surface of the oven.

  • Page 18: Test Procedure

    TEST PROCEDURES PROCEDURE COMPONENT TEST LETTER MAGNETRON ASSEMBLY TEST HIGH VOLTAGES ARE PRESENT DURING THE COOK CYCLE, SO EXTREME CAUTION SHOULD BE OBSERVED. DISCHARGE THE HIGH VOLTAGE CAPACITOR BEFORE TOUCHING ANY OVEN COMPONENTS OR WIRING. To test for an open filament, isolate the magnetron from the high voltage circuit. A continuity check across the magnetron filament leads should indicate less than 1 ohm.
  • Page 19 TEST PROCEDURES PROCEDURE COMPONENT TEST LETTER Checking with a high ohm scale, if the high voltage capacitor is normal, the meter will indicate conti- nuity for a short time and should indicate approximately 10 MΩ once the capacitor is charged. If the above is not the case, check the capacitor with an ohmmeter to see if it is shorted between either of the terminals and case.
  • Page 20 TEST PROCEDURES PROCEDURE COMPONENT TEST LETTER OVEN THERMAL CUT-OUT (on the side of steam duct) A continuity check across the thermal cut-out terminals should indicate a closed circuit unless the tem- ο ο perature of the oven thermal cut-out reaches approximately 302 F (150 C).

  • Page 22 TEST PROCEDURES PROCEDURE COMPONENT TEST LETTER KEY UNIT TEST If the display fails to clear when the STOP/CLEAR pad is depressed, first verify the flat ribbon cable is making good contact, verify that the door sensing switch (stop switch) operates properly; that is the contacts are closed when the door is closed and open when the door is open.
