Electronic Functional Description
Temperature Control Operation
For any temperature setting, outputs will be turned
off/on based on cut-in/cut-out temperatures
determined by resistance levels of freezer and
refrigerator thermistors.
As the temperature decreases, resistance increases.
As the temperature increases, resistance decreases.

An open thermistor or thermistor circuit will result in
failure of refrigerator to cool.
Shorted thermistor will cause refrigerator to run 100
percent of time except for defrost.
• Freezer temperature setting and thermistor value
will determine if compressor/condenser fan and
evaporator fan switches are open or closed.
Compressor/condenser fan switch must be open
for 6 minutes before switch can close again
(compressor dwell time).
• Cut-out and cut-in temperature values must be
reached and maintained for 15 seconds before
output state will change (digital delay).
• Refrigerator and freezer control calibration can be
adjusted in Program Mode B.

Damper Control
• Refrigerator temperature setting and thermistor
value will determine if damper control heater
switch is to be open or closed.
• Damper closes at 48°F.
• Damper opens at least 1/4" when minimum voltage
is applied at 40°F ambient.
