Disassembly Procedures
!
WARNING

Diode/Circuit Protector

1. Disconnect power to oven and remove outer case,
(see "Outer Case" procedure).
2. Discharge high voltage capacitor, (see "High Voltage
Capacitor" section).
3. Disconnect component from high voltage capacitor
and remove screw securing diode to ground.
4. Replace component and reverse procedure to
reassemble.

Transformer

1. Disconnect power to oven and remove outer case,
(see "Outer Case" procedure).
2. Discharge high voltage capacitor, (see "High Voltage
Capacitor" section).
3. Disconnect and label wire leads from transformer.
4. Place unit on it's back to gain access to mounting
screws.
5. Remove screws securing transformer and remove.
6. Replace transformer and reverse procedure to
reassemble.

2. Disconnect and label wires.
3. Carefully lift tabs to release assembly from plastic
locating pins.
4. Replace component(s) and reverse procedure to
reassemble.
!
CAUTION
Before replacing a blown monitor fuse, test the primary
interlock switch, secondary interlock switch, monitor
switch, and power relay contacts for proper operation.
If the monitor fuse is blown by a failed switch
operation, all switches and controller must be
replaced.

Magnetron

Magnetrons are located on the side of the cavity.
1. Disconnect power to oven and remove outer case,
(see "Outer Case" section).
2. Discharge high voltage capacitor, (see "High Voltage
Capacitor" section).
3. Remove terminal plug from filament terminals.
4. Remove screws securing duct assembly and place to
the side to gain access to magnetrons.
5. Remove screws securing magnetron being replaced to
the wave guide.
Chassis
6. Replace magnetron and reverse procedure to
reassemble.
NOTE: When replacing magnetron, make sure gasket is
in correct position and in good condition.
!
CAUTION
During replacement of magnetron, be certain the R.F.
anode gasket is in place around the anode stud.
!
WARNING
A microwave leakage test must be performed anytime
a magnetron assembly is removed, replaced,
disassembled, or adjusted for any reason.
