Thermocouple
Lead
To check the cut-in/cut-out temperatures,
attach the bulb of thermistor temperature
tester to the control feeler tube and set con-
trols at midposition.
1. Disconnect the unit from the power
source.
2. Open the fresh food door and remove
any loose items on the top shelf.
3. Remove the light shield cover by pull-
ing down on the back corners of the
cover, and sliding the cover forward.
Temperature Control Replacement
Compressor Runs Continuously
1. Turn the control knob to OFF. If the com-
pressor continues to run, proceed to
step 2. If the compressor stops, check
that the feeder tube is positioned prop-
erly and that the air flow through the con-
trol housing is not restricted. If the
feeler tube is positioned properly and
there is no air restriction, check the con-
trol operating temperatures.
2. Remove the control far enough to re-
move one of the wires from its termi-
nal. If the compressor continues to run,
there is a short in the unit wiring.
Allow the compressor to complete two or
three complete cycles. If the temperature
readings are not within two degrees of the
requirements the control is defective and
must be replaced. Do not attempt to
recalibrate.
A defective control may cause the compres-
sor to run continuously or not at all. If ei-
ther of these conditions exist, check as
follows:
Compressor Won't Run
1. Remove the control enough to expose
its terminals.
2. Short across the control terminals. If
the compressor starts, install a new
control. If the compressor fails to start,
check the defrost timer, compressor
receptacle, and unit wiring for defects.
