Fresh Food Temperature Control
Fresh food temperature is regulated by an
adjustable air damper control mounted
behind the control console, at the left
side of the control panel. The damper DAMP'FR---
opens and closes automatically, by means of
a
mechanical linkage with a capillary and
bellows assembly in reaction to changes in
the fresh food air temperature. Upon
temperature rise in the fresh food
compartment, the damper gradually opens.
If the temperature continues to rise, the
damper will continue to open, providing a
supply of cold
air upon demand -- as sensed
by the capillary. The capillary is coiled
and positioned in front of the control
body.
NOTE: To prevent abnormally warm fresh
food temperatures, the capillary must not
touch
any metal surfaces.
For access to the control and mechanical
linkage: remove the screws and bracket
attached to the
damper housing.
To replace the control and damper housing
as an assembly, remove the light shield,
control console,
knobs and extensions.
Then, remove the screws that secure the
control
panel to the liner. Remove the foam
strip and cut through the RTV sealer around
the damper housing and then, remove the
screws holding the damper housing to the
compartment divider.
To Test the Fresh Food Damper Control:
Uncoil the capillary and hold an ice cube
in contact with the capillary. The damper
should slowly close in response to the cold
temperature of the ice cube.
Then, while
grasping the
end of the capillary by hand,
the damper should open.
