Temperature Control Operation
For any temperature setting, outputs will be turned off/on based on cut-in/cut-out temperature determined
by resistance levels of freezer or refrigerator thermistors.
Refrigerator and Freezer Thermistor (NTC)
As temperature decreases, resistance increases. As temperature increases, resistance decreases.
Note: Open thermistor or thermistor circuit or a shorted thermistor will result in refrigerator continuing to
cool with error code displayed. The affected section will call for cooling 100 percent of time except during
defrost cycle
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). Refrigerator temperature setting and thermistor value will determine if fresh food
switch is open or closed. Cut-out and cut-in temperature values must be reached and maintained for 15 seconds be-
fore output state will change (digital delay). Refrigerator and freezer control calibration can be adjusted in Program
Mode A.
