How to Test Primary Interlock and Door Sensing
Switches
1. Disconnect power and partially remove the oven
from its installation. (See the Removing Upper
Oven section in this guide.)
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 the door
open and the door closed. Normal readings are
as follows:
• Door Closed: 0 W
• Door Open
How to Test the Monitor Switch

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 the door
open and the door closed. Normal readings are

• Door Open: 0 W
How to Test Interlock System
1. Disconnect power, remove the outer cover (see
the Removing Upper Oven section in this guide)
and discharge the capacitor.
2. Check 20 amp fuse for continuity and proper
size. Do not use any other fuse or size except 20
amps.
