Diagnostics
Temperature Control Operation (continued)
Open thermistor or thermistor circuit will result in failure to cool. Shorted thermistor will cause refrigerator
to run 100 percent of time except for 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 before output state
will change (digital delay). Refrigerator and freezer control calibration can be adjusted in Program Mode B.
