Left and Right Door Switch Assemblies

The primary interlock, monitor interlock, and door sensing (secondary interlock) switches are mounted on plastic latch boards. The latch boards are attached to the left and right side of the oven cavity. The left side latch board contains the door sensing (secondary interlock) switch. The right side latch board contains the primary interlock and the monitor interlock switches.

How to Test Primary Interlock and Door Sensing Switches:

1.Disconnect power and partially remove the oven from it’s installation. (See Oven Removal / Partial Removal.)

2.Remove the single Phillips-head screw that holds each door switch access cover to the outer cover.

3.Remove the primary interlock and door sensing switch leads to isolate each switch.

4.Check continuity of each switch with door open and door closed. Normal readings are as follows:

Door Closed: 0

Door Open: Infinity

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.

1.Disconnect power and partially remove the oven from it’s installation. (See Oven Removal / Partial Removal.)

2.Remove the single Phillips-head screw that holds the right side door switch access cover to the outer cover.

3.Remove the monitor switch leads to isolate the switch.

4.Check continuity of the switch with door open and door closed. Normal readings are as follows:

Door Closed: Infinity

Door Open: 0

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.

3.Remove monitor switch leads to isolate switch. Check continuity of switch with door open and door closed.

Door Closed: Infinity Ω

Door Open: 0 Ω

4.Reconnect switch wiring.
