Part Replacement; When The 10A Fuse Is Blown Due To The Operation Of The Short Switch; Avoid Inserting Nails, Wire Etc. Through Any Holes In The Unit During Operation; Confirm After Repair - Panasonic NN-GD566M Service Manual

to touch the chassis ground side first and then short to the output terminals.
Discharging the high voltage capacitors
WARNING
There is high voltage present with high current capabilities in the circuits of the primary and secondary windings, choke
coil and heat sinkof the inverter. It is extremely dangerous to work on or near these circuits with the oven energized. DO
NOT measure the voltage in the high voltage circuit including the filament voltage of the magnetron.
WARNING
Never touch any circuit wiring with your hand or with an insulated tool during operation.

3.3 Part replacement.

When any part or component is to be replaced, always ensure that the power cord is removed from the wall outlet.
3.4 When the 10A fuse is blown due to the
operation of the short switch:
WARNING
When the 10A 250V fuse is blown due to the operation of the interlock monitor switch, replace all of the components
(primary latch switch, short switch and power relay B (RY1)).
1. This is mandatory. Refer to "adjustments and measurements" for the location of these switches.
2. When replacing the fuse, confirm that it has the appropriate rating for these models.
3. When replacing faulty switches, be sure the mounting tabs are not bent, broken or deficient in their ability to hold
the switches.
3.5 Avoid inserting nails, wire etc. through any
holes in the unit during operation.
Never insert a wire, nail or any other metal object through the lamp holes on the cavity or any holes or gaps, because
such objects may work as an antennaand cause microwave leakage.

3.6 Confirm after repair

1. After repair or replacement of parts, make sure that the screws of the oven, etc. are neither loosen or missing.
Microwave might leak if screws are not properly tightened.
2. Make sure that all electrical connections are tight before inserting the plug into the wall outlet.
3. Check for microwave energy leakage. (Refer to procedure for measuring microwave energy leakage).
