  • Page 5 2. CAUTIONS TO BE OBSERVED WHEN TROUBLESHOOTING Unlike many other appliances, the microwave oven is high-voltage, high-current equipment. Though it is free from danger in ordinary use, extreme care should be taken during repair. CAUTION Servicemen should remove their watches whenever working close to or replacing the magnetron.

  • Page 6: Check The Grounding

    2.1. Check the grounding Do not operate on a 2-wire extension cord. The microwave oven is designed to be grounded when used. It is imperative, therefore, to make sure it is grounded properly before beginning repair work. 2.2. Warning about the electric charge in the high voltage capacitor For about 30 seconds after the oven is turned off, an electric charge remains in the high voltage capacitor.When replacing or checking parts, remove the power plug from the outlet and short the terminal of the high voltage capacitor (terminal of lead wire from diode) to chassis ground...

  • Page 7: Avoid Inserting Nails, Wire, Etc. Through Any Holes In The Unit During Operation

    WARNING When the 8 Amp fuse is blown due to operation of the interlock monitor switch, you must replace all of the components (Primary latch switch, Door switch, Short switch and Power relay B (RY1)). 1. This is mandatory. Refer to “Adjustments and Measurement” for these switches.

  • Page 8: Measurements And Adjustments

    IMPORTANT NOTICE 1.The following components have potentials above 2000V while the appliance is operated. * Magnetron * High voltage transformer * High voltage diode * High voltage capacitor Pay special attention to these areas. 2.When the appliance is operated with the door hinge or magnetron adjusted incorrectly, the microwave leakage can exceed more than 5mW/cm .

  • Page 9: Measurement Of Microwave Output

    3.2. Measurement of microwave output The output power of the magnetron can be determined by performing IEC standard test procedures. However, due to the complexity of IEC test procedures, it is recommended to test the magnetron using the simple method outlined below. Necessary Equipment: - 1 liter beaker - Glass thermometer...
