Disassembly Procedures
!
Diode
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 diode from high voltage capacitor and
remove screw securing diode to ground.
4. Reassemble in reverse order.
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. Remove screws securing transformer and remove.
5. Reassemble in reverse order.
Fuse Block / Filter Assembly
1. Disconnect power to oven and remove outer case,
(see "Outer Case" section).
2. Disconnect and label wires.
3. Carefully lift rear of fuse block assembly to release
assembly from locating pin.
4. Slide fuse block assembly towards front of oven to
remove.
5. Reassemble in reverse order.
Fuse
Fuse Removal
Fuse is located on the noise filter board.
1. Disconnect power to oven and remove outer case,
(see "Outer Case" section).
2. Remove and replace fuse, reassemble in reverse
order.
!
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.

WARNING
16023053 Rev. 0
To avoid the risk of electrical shock, personal injury or
death, disconnect power to oven and discharge
capacitors before following any disassembly procedure.
Magnetron
Magnetron is mounted 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 filter assembly from magnetron terminals.
4. Remove air duct.
5. Remove screws securing magnetron to the wave
guide.
6. Reassemble in reverse order.
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.
!
W ARNING
A microwave leakage test must be performed anytime
a magnetron assembly is removed, replaced,
disassembled, or adjusted for any reason.
Fan Motor
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 rear air guide.
4. Remove screws securing diode to back panel.
5. Disconnect and label wires to high voltage capacitor.
6. Remove screws securing fan shroud to back panel
and remove fan shroud from cavity.
