Problems Controlling Cellar Temperature
Problems are occurring even though the unit seems to be fully operational—evaporator fan
blows air into the cellar and compressor and condenser fan runs.

Rest thermostat to higher heating temperature
Thermostat not controlling
temperature
Wiring integrity compromised (shorted), replace
