Interlock Switches
Primary switch is operated by bottom latch arm.
Interlock Switch Removal
1. Disconnect power to oven and remove outer case,
(see "Outer Case" procedure).
2. Remove control panel, (see "Control Panel" section).
3. Test interlock switches before removing, (see testing
procedures).
4. Disconnect and label wire connections.
5. Remove switches by carefully releasing locking tabs
on switch bracket and tilting switches to remove from
switch bracket.

NOTE: After repairing the door or the interlock system, it
is necessary to check the switch continuity
before operating the oven.
!
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.

CAUTION
To avoid the risk of electrical shock, personal injury or
death, disconnect power to oven and discharge
capacitors before following any disassembly procedure.
Adjusting Interlocks
The interlock monitor, primary, and secondary switches
act as a final safety switch, protecting the operator from
microwave energy. After adjusting the interlock switch
assembly, verify wires are correctly connected.
For door fit and switch operation, switch bracket is
adjustable.
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.
A microwave leakage test must be preformed anytime
a door assembly is removed, replaced, disassembled,
or adjustment of switch bracket is made.
High Voltage Capacitor
High voltage capacitor 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 capacitor.
3. Remove and label wire leads from capacitor
terminals.
4. Push the end of capacitor straps towards rear of
oven to release strap from fan shroud.
5. Slide capacitor out of slots and remove capacitor.
6. Reassemble in reverse order.
