High Voltage Transformer
The high voltage transformer is located on the
right side of the microwave oven, beneath the
magnetron.
WARNING
: Prior to servicing the transformer, be
certain the capacitor is discharged. Manually
discharge by placing an insulated-handle
screwdriver between the diode connection of the
capacitor and the oven chassis ground.
To remove the high voltage transformer:
Remove the control panel assembly. (See

Capacitor and Diode
The capacitor has an internal shunt resistor to
automatically discharge the capacitor when the
oven turns "off". Under normal operation, the
capacitor should fully discharge within 30 seconds.
WARNING
: Always be certain the capacitor is
discharged before servicing. Mechanically discharge
the capacitor by placing an insulated-handle
screwdriver between the diode connection of the
capacitor and the oven chassis ground.
Note
: Use the screw head close to the capacitor to
ensure ground metal contact.
To remove the capacitor and diode:
Remove the control panel assembly. (See
