Temperature does not go below 59 deg. refrigerator side.

Auto Damper models, The Auto Damper model refrigerator has
two controls and both have capillary sensing.
The Auto Damper controls the fresh
food temperature and the Freezer Temperature
Control guides the freezer temperature.
The fresh food compartment temperature
is maintained by a damper assembly located
at the back of the temperature control
housing. Changes in air temperature
cause the damper door to open and close.
A control rod and gear connect the fresh
food control knob to the damper control.
Turning the fresh food control knob to the
COLDEST position increases the flow of
freezer air into the fresh food section. The
freezer compartment temperature control
warms at a faster rate and cools at a slower
rate, increasing the compressor run time
necessary to maintain a satisfied freezer
temperature control.
Turning the fresh food control knob to a
WARMER setting decreases the flow of
chilled air into the fresh food section. The
freezer compartment temperature control
warms at a slower rate and cools at a faster
rate, decreasing the compressor run time
necessary to maintain a satisfied freezer
temperature control.
It is ver possible that the auto damper has failed and will need to be cosidered as a likely cause.
