is located behind the top access cover. A single
Phillips-head screw attaches the capacitor and
diode to the oven chassis.
1. When disconnecting the wires and diode from
the capacitor, note wire and diode locations.
2. The capacitor wires have locking tabs. It is
helpful to fi rst remove the capacitor, capacitor
bracket, and diode as one assembly.
3. 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 pliers. Gently squeeze
the pliers jaws together while pulling the
electrical terminal from the capacitor.

and electrician's gloves under Kevlar gloves or
equivalent protective gloves when discharging the
capacitor.
The capacitor has an internal discharge
Note:
resistor that automatically discharges the capacitor
when the oven turns OFF. Under normal operation,
the capacitor should fully discharge within 30
seconds.
The magnetron converts the high voltage supplied
by the transformer, capacitor, and diode into radio
frequency waves of electromagnetic cooking

The oven must be removed to access the

The magnetron is located behind the top access
cover. The top access cover is held in place by 2
Phillips-head screws. The magnetron is held in place
by 4 Phillips-head screws. The magnetron TCO
bracket must be removed and the fi lament wire
harness must be disconnected before removing the
magnetron.
To check the magnetron fi lament for continuity it is
necessary to disconnect the fi lament wire harness.
The magnetron fi lament has a resistance value of
less than 1 Ω.
