When the control is off, the damper should close and
the fan should shut off, if the compressor is not running.
To replace Fresh Food Compartment Control, remove
screw and drop housing (follow freezer control
instructions). Snap control out of housing, then remove
damper control and cap tube for control. Connect wiring
to new control as shown in Figure 11.
Place control metal wing in solid clip first, then snap
other side in place. Route wires and cap tube behind
boss. (See Figure 12.)

Air Damper Control
The air damper is used to control the fresh food
compartment temperature by controlling air flow into the
food compartment from the freezer. (See Figure 13.)

Damper Control
When the food compartment control calls for cooling,
the contacts in the control will open from 2 to 3 and
close from 2 to 1. This will start the damper motor running,
open the damper, and start the freezer compartment
fan running. (See Figure 14.)
As the damper motor opens the damper, the switches
on the damper will change from NO (normally open) to
the NC (normally closed) position one at a time to prevent
the stopping of the motor in a 1/2 open position, as a
result of a power outage as the damper is opening or
closing. When both switches have reached the NC
position, the damper will be all the way open and the
motor will stop. (See Figure 15.)
The damper will remain open and the fan motor will
continue to run as long as the food compartment control
calls for cooling. Once the food compartment control is
satisfied, the contacts in the cold control will open from
2 to 1 and close from 2 to 3. This will start the damper
motor running again, closing the damper and shutting
off the freezer fan motor. (See Figure 16.)
As the damper motor closes the damper, the switches
on the damper will change from the NC to the NO position
one at a time. When both switches have reached the NO
position, the damper will be all the way closed and the
motor will stop. (See Figure 17.)
There are two types of damper controls. One has 3
switches; two at the top for the damper motor and one at
the bottom to control the freezer fan motor. This type is
used on models with a defrost timer.
The other type has two switches at the top only and is
used on models with an Adaptive Defrost Control (ADC).
