I was reading about a hi limit switch and it sounds like what is going on with my GE wall combo unit. How is this replaced? Does the unit need to be pulled from the wall?
Answer Hello Neil. Oven Thermal Switch
Note: Oven thermal switch is used only on the
27-in. wall oven models.
A self-resetting, disc-type thermal cutout switch is
mounted to the rear of the oven. The switch will
open L2 to the heating elements in the event of an
overtemperature condition. Single, lower oven, and
microwave/oven combination switch opens at
284 °F (140 °C) and closes at 254 °F (123 °C).
Upper oven switch opens at 302 °F (150 °C) and
closes at 272 °F (133 °C).
There is no indication to the customer when the
switch opens or closes. Note: Oven must be removed from installation for
access to the thermal cutout switch on the back of the unit.
