Damper Assembly
The damper assembly is on the top right side of
the oven cavity. When the damper door is closed,
moisture is retained in the oven cavity. When the
damper door is open, moisture is released, allowing
food to be more crisp.
The outer cover must be removed to access or
observe operation of the damper assembly. (See
Oven Removal / Partial Removal
The damper assembly is held in place by 2 pins
and 3 Phillips-head screws that attach the damper
assembly to the oven chassis. When removing,
move the damper assembly inward to disengage
the 2 pins from the vent tube.

Damper Door Switch
The damper door sensing switch is mounted to the
damper assembly. The switch monitors the damper
door position and provides this information to the
main PCB, which controls the operation of the
damper
door motor.
When the
damper
door is
closed, the
switch is
open. The
motor will
run until
the switch
sends the door closed signal. If the damper door
sensing switch circuit shorts (or opens), the damper
motor will run continually. The damper motor has
an approximate resistance value of 3.36 K
Ω
.
Blower Assembly
A blower protects the oven from too much heat
inside the oven cavity. It automatically turns on at
low speed if it senses too much heat. The blower will
automatically turn off when the internal parts are
cool. It may stay on for 30 minutes or more after the
oven control is turned off.
The blower motor has an approximate resistance
value of 14
Ω
.
Remove the foam seal from the blower bracket.
Remove wiring from the guides in the blower
bracket and from the retainers on the blower
housing.
