Oven Thermal Switch
A self-resetting, disc-type thermal cutout switch is
mounted to the rear of the oven. The switch will
open the L2 leg of the power to the heating
elements in the event of an overtemperature
condition. Single and lower oven switch opens at
250 °F. Upper oven switch opens at 330 °F. All
switches close at 220 °F.
There is no indication to the customer when the
switch opens or closes.
Lock Thermal Switch
A thermal switch is in the lock switch circuit in the
normally closed position.
The single wall oven switches and upper and
lower double wall oven switches open at 216 °F
and automatically close when temperatures cool
below 177 °F. The lower oven switch of the
microwave wall oven (JKP85) opens at 240°F and
automatically closes when the temperature cools
below 190 °F.
If the thermal switch opens during:
1. Oven Temperature Below 600 °F. Program is
cancelled when thermal switch opens. Lock
motor will run and the words LOCKED DOOR
will be flashing in the display.
2. Oven Temperature Above 600 °F. Any mode of
operation control will go to -F9- or -F2- 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.
Fan Switch
The fan switch is a self-resetting switch located on
the vent box. The switch will turn the fan on in any
mode of operation when it detects a vent tempera-
ture above 138 °F. The fan will turn off once it has
cooled below 106 °F.
Note: To access the lower oven fan switch, the
oven must be removed from the installation, and
the upper oven must be removed from the lower
oven.
