Microwave High-Voltage Section

WARNING: Prior to servicing the high-voltage
capacitor or diode, remove power to the oven
(turn off the circuit breaker).
WARNING: Always be certain the capacitor is
discharged before servicing. Manually discharge
by placing an insulated-handle screwdriver
between the diode connection of the capacitor
and the oven chassis ground. Use screw head
close to capacitor to ensure ground metal contact.
The microwave high-voltage section is located on
the right side of the Advantium oven. To access,
remove the top and right access covers (see page
28).

Remove Magnetron Fan Motor Assembly

Note: The electrical terminal ends which attach to
the high-voltage capacitor have locking tabs on
them. These tabs cannot be seen because they
are encased in plastic. To remove these terminals,
grasp the top and bottom of the terminal with
needle-nose plier jaws. Gently squeeze the plier
jaws together while pulling the electrical terminal
from the capacitor.
Capacitor Capacitor
1. Disconnect the red and white high-voltage
transformer leads from the capacitor.
2. Remove the top screw from the fan motor
assembly.
