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.
