WARNING There is high-voltage present, with high-current capabilities in the circuits of the primary, and secondary windings, choke coil and heat sink of the Inverter. It is extremely dangerous to work on or near these circuits with oven energized. DO NOT measure the voltage in the high voltage circuit including filament voltage of magnetron.

WARNING Never touch any circuit wiring with your hand nor with an insulated tool during operation.

8.3. When parts must be replaced, remove the power plug from the outlet. 8.4. When the 18 Amp fuse is blown due to the operation of short switch:
WARNING When the 18 Amp. fuse if blown due to the operation of short switch, you must replace Primary latch switch and short switch. Also replace power relay B (RY1) when the continuity check reads shorted contacts (1-2).

1. This is mandatory. Refer to "Measurements and Adjustments" for these switches. 2. When replacing the fuse, confirm that it has the appropriate rating for these models. 3. When replacing faulty switches, be sure mounting tabs are not bent, broken or otherwise deficient in their ability to hold the switches. 8.5. Avoid inserting nails, wire, etc. through any holes in the unit during operation.
WARNING Never insert a wire, nail or any other metal object through the lamp holes on the cavity or any other holes or gaps, because such objects may work as an antenna and cause microwave leakage.
