Air Damper Control
To remove the air damper, remove both gear racks, the damper gear, and the two mounting screws.
Using a putty knife, carefully pry the foam nozzle and gasket from the air damper. Press the wiring
harness and temperature control capillary from the slot in the air damper housing. A gasket will be
supplied with the replacement air damper control and foam nozzle.
Freezer Temperature Control
To remove the temperature control, remove both
gear racks, both gears, and the control housing
cover (bottom); pull the vinyl sleeve from the control
capillary. Remove the screws that mount the
temperature control and the air damper (but do not
remove the foam nozzle from the air damper).
Press the wiring harness grommet partially out of
the slot in the air damper housing, and pull the
control capillary from the slot.
When installing the temperature control, exercise
care to prevent the tip of the capillary from damaging
the foam nozzle. Insert the capillary fully into the
sleeve and adjust the length of the capillary
(extending through the foam nozzle) so that it is fully
covered by the sleeve inside the foam nozzle. Then
press the wiring harness grommet back into the slot
in the air damper housing.
Module Reassembly
When reassembling the control module, the gears
for the air damper and temperature control must be
firmly pressed onto the respective control shafts
and correctly positioned before installing the racks.
(Although both gears are the same diameter, they
are not interchangeable.) Rotate the damper gear
fully counter-clockwise so that the finger is pointing
forward. Rotate the temperature control gear so
that the alignment mark is toward the rear. Then
slide the control rack onto the left end of the control
channel and lift the serrated arm to engage the
control gear so that the marks on the arm and gear
are aligned. Next, slide the damper rack onto the
right end of the control channel until the serrated
arm engages the damper gear.
Check the meshing of the damper rack with the damper gear to be sure engagement is neither too tight
nor too loose. If adjustment is needed, loosen the air damper mounting screws and move the damper
gear in or out as required. Position both racks so that the alignment marks can be observed through the
windows in the racks. Verify proper alignment of the marks at both sets of gears before installing the
control module in the fresh food compartment.
