Replacing the oven sensor

The oven temperature sensor can be replaced after removing the oven shroud.

Before proceeding, turn off the oven and let it and any heated zones cool

down. Turn off the main power switch and unplug the power cord.

Remove the oven shroud as described in the Replacing the oven shroud

assembly procedure in this section.

Loosen the two Torx T-20 screws securing the sensor retainer to the back

of the shroud.

Slide the old sensor out of the retainer. Thread a new sensor through the

opening in the rear of the oven.

Slide the new sensor under the retainer. One of the grill holes on the front

of the shroud is stamped. Make sure that the end of the sensor is

positioned behind the stamped hole before tightening the retainer.
