Disassembly Procedures
To avoid the risk of electrical shock, personal injury, or death,
disconnect power to oven and discharge the capacitors before
following any disassembly procedure.

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
1
/
64
–inch (0.5 mm).
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 ION
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.
4. Remove screw securing capacitor strap to plate.
5. Slide capacitor out of capacitor strap and remove
capacitor.
6. Replace capacitor and reverse procedure to
reassemble.
NOTE:
When replacing H.V. components, route H.V.
wires at least
1
/

" / 6 mm from all grounded
surfaces to prevent arcing.
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. Replace diode 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. Remove screws securing transformer and remove.
5. Replace transformer and reverse procedure to
reassemble.
Fuse / Fuse Block / Filter Assembly
1. Disconnect power to oven and remove outer case,
(see "Outer Case" section).
2. Disconnect and label wires.
3. Remove fuses to gain access to screws securing
assembly.
4. Carefully lift tab to release assembly from locating
pin.
5. Replace component(s) and reverse procedure to
reassemble.
CAUT ION
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.
