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
sink of 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 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 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 short
switch, the primary latch switch and short switch must be replaced.
It is also important to change the power relay 1 (RY1) when the
continuity test shows shorted contacts.
1. This 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.
