Remove the single Phillips-head screw that
holds each door switch access cover to the
outer cover.
Remove the primary interlock and door sensing
switch leads to isolate each switch.
Check continuity of each switch with door open
and door closed. Normal readings are as follows:
• Door Closed: 0 Ω
• Door Open: Infi nity
How to Test the Monitor Switch:
Note: The right side latch pawl pushes horizontally
and actuates the lever of the monitor interlock,
opening the switch.
Disconnect power and partially remove the
oven from it’s installation. (See

• Door Open: 0 Ω
How to Test Interlock System:
1. Disconnect power, remove the outer cover (See
Oven Removal / Partial Removal) and discharge
capacitor.
2. Check 20 amp fuse for continuity and proper
size. Do not use any other fuse or size except 20
amp.
