Disassembly Procedures
WARNING
1. Disconnect power to oven and remove outer case,
(see "Outer Case" procedure).
2. Loosen switch bracket mounting screws.
3. Close oven door, move switch bracket toward rear of
oven until door gap is less than
4. Hold switch bracket securely for proper switch
operation and door fit, retighten screws.
5. Open oven door slowly, watching the switches. Verify
switches release in the following order.
• Primary interlock switch
• Secondary interlock switch
• Interlock monitor switch
NOTE: Adjust the switch bracket until all switches
operate in proper sequence.
6. Close the oven door slowly, watching the switches.
Verify switches activate in the following order.
• Interlock monitor switch
• Secondary interlock switch
• Primary interlock switch
7. When proper switch sequence has been achieved,
tighten the switch bracket securely.
CAUT IO N
A microwave leakage test must be preformed anytime
a door assembly is removed, replaced, disassembled,
or adjustment of switch bracket is performed.
High Voltage Capacitor
High voltage capacitors should always be discharged by
shorting a terminal to a chassis ground. The capacitor
has a internal "shunt" resistor, but the mechanical
discharge should always be performed to avoid personal
injury.
High Voltage Capacitor Removal
1. Disconnect power to oven and remove outer case,
(see "Outer Case" procedure).
2. Discharge high voltage capacitors.
3. Remove and label wire leads from capacitor
terminals.

To avoid the risk of electrical shock, personal injury, or death,
disconnect power to oven and discharge the capacitors before
following any disassembly procedure.
4. Remove screw securing capacitor strap to plate.
5. Slide capacitor out of capacitor strap and remove
6. Replace capacitor and reverse procedure to

Transformer
1. Disconnect power to oven and remove outer case,
2. Discharge high voltage capacitor, (see "High Voltage
3. Disconnect and label wire leads from transformer.
4. Remove screws securing transformer and remove.
5. Replace transformer and reverse procedure to
Fuse / Fuse Block / Filter Assembly
1. Disconnect power to oven and remove outer case,
2. Disconnect and label wires.

CAUT IO N
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, interlock assembly must be
replaced.
