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 fans run
Cellar temperature is low (below 51° when
unit is running
Possible Cause
Solution
Remote interface controller set too low on
cooling
Remote interface controller not controlling
temperature
Reset remote interface controller to higher
cooling temperature
Wiring integrity compromised (shorted),
replace wiring
Cellar temperature is too cold (below 51°)
when unit is not running
Possible Cause
Solution
Too much heat loss to adjacent spaces
Increase insulation around the ductwork and
doorways - Add heater
Cellar temperature is too high, but supply
air is cold
Possible Cause
Solution
Not enough evaporator airflow
Cellar heat loads are too high
Remove blockage in supply or return
Check and clean coil
Coil frozen – shut off unit for two hours
Install additional insulation Replace with
larger sized unit
