(especially at sensor in rear)

Oven temperature

-F3-

• Disconnect power. Disconnect sensor harness from control. Measure

sensor resistance (white leads) to be 1080 ohms at room temperature
with 2 ohms per degree change.

• Look for damaged harness terminals if not a bad sensor

Open oven sensor
(over 2900 ohms)

Shorted oven sensor
(under 950 ohms)

-F4-

• Disconnect power. Disconnect sensor harness from control. Measure

sensor resistance (white leads) to be 1080 ohms at room temperature
with 2 ohms per degree change.

• Separate sensor from harness to determine fault.

Shorted key

-F7-
