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 or with an insulated
tool during operation.
4.3. Part replacement.
When any part or component is to be replaced, always ensure that the power cord is removed
from the wall outlet.
4.4. 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, secondary 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
