Damper Door Test
To test damper doors:
1. Select Warm/Reheat mode.
2. Select Keepwarm Lo program.
3. Select Moist setting.
4. Press start and run for 5 seconds. Open the
door and visually check to see if both damper
doors are closed.
5. Close the door and press Clear/Off.
6. Select Warm/Reheat mode.
7. Select Warm/Reheat Lo program.
8. Select Crisp setting.
9. Press start and run for 5 seconds. Open the
door and visually check to see if both damper
doors are open.
Heater Resistance Values
Resistance can be checked across a heater using
the line-in side of the power cord and the heater
connector at the main PCB or sub PCB. The oven
door must be closed when checking through the
power cord.
The following chart lists the wattage and
resistance values for each of the four heaters.

Thermal Cut-Outs (TCOs)
The following chart lists each TCO, the
temperature it will open at, and the temperature it
will close at. Use an ohmmeter to check for an
open TCO.

Oven Door Switches
Primary Interlock Test
1. Remove the grille and discharge the capacitor.
2. Check continuity between switch terminals.
Normal readings are as follows:
• Door closed: 0 ohms.
• Door open: infinite ohms.
Door Sensing Switch Test
1. Remove the grille and discharge the capacitor.
2. Check continuity between switch terminals.
Normal readings are as follows:
s t
• Door closed: 0 ohms.
s t
• Door open: infinite ohms.
Monitor Switch Test
s t
The bottom latch pawl pushes horizontally and
actuates the lever of the monitor interlock opening
the switch.
s t
1. Remove the monitor switch leads to isolate the
switch.
2. Check continuity between switch terminals.
Normal readings are as follows:
• Door closed: infinite ohms.
• Door open: 0 ohms.
