WARNING
There is high-voltage present, with high-current
capabilities in the circuits of the high voltage
winding and filament winding of the high voltage
transformer. 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.
7.3. When parts must be replaced, remove the power plug from the
outlet.
7.4. When the 8 Amp fuse is blown due to the operation of short
switch:
WARNING
When the 8 Amp fuse is 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 continulty check reads shorted
contacts(1-2).
1. This is mandatory. Refer to “Adjustments and Measurement” for
these switches.
2. When replacing the fuse, confirm that it has the appropriate rating
for these models.
