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.

Lock Thermal Switch

The thermal switches are located in the compo-
nent compartment (see photo). The lock thermal
switch circuit is in the normally closed position.
There are two thermal limit switches. One is for
thermal protection during selfclean mode (located
in the yellow neutral wire of the door lock circuit). It
opens between 240 °F (116 °C) and 365 °F
(185 °C), and closes between 190 °F (88 °C) and
293 °F (145 °C), depending on model.
The other thermal switch is for sensing cooling fan
operation during non-selfclean modes only (lo-
cated in unlock switch side of door lock motor
circuit). It opens between 176 °F (80 °C) and 212
°F (100 °C) and closes between 149 °F (65 °C)
and 185 °F (85 °C), depending on model.
If the thermal switch opens in any mode of opera-
tion, the control will go to -F9- failure code. When
this condition exists, check the fan operation (look
for obstructions) and inspect oven installation
(make sure grill areas are not blocked), oven
insulation, and lock circuit.
