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 .

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 .

Blower Assembly

To remove the blower assembly:

1.Remove the oven from cabinet or wall opening and remove the outer cover. (See Oven Removal / Partial Removal.)

2.Disconnect the blower motor wiring and the oven lamp wire harness.
