TROUBLESHOOTING GUIDE
Ice forming on evaporator units
Possible cause
Solution
Evaporator filter or coil is dirty
Remove the filter and wash it, then clean the coil with a vacuum .
If coil is very dirty, use a spray bottle with a small amount of liquid
dish detergent or coil cleaner . Spray coil, let set for five minutes, then
flush with fresh water .
There is something blocking the supply and/or return air
Remove blockage
The evaporator fan is not turning on
Call a service tech to troubleshoot
The evaporator units have not gone through an Anti-Frost Cycle yet
Check the coil for surface ice . Melt with blow drier until coil is warm
to the touch . Soak up water with a towel .
If evaporator units continue to ice
Observe ice formation pattern . If only part way up the coil face, the
system could be low on refrigerant . If all the way up, the coil may be
dirty or airflow is blocked .
System does not run/power up
Possible cause
Solution
Evaporator units are not plugged in
Make sure the units are plugged into an outlet
Line voltage rating is incorrect for the system
Check line voltage to make sure there is 110V-120V
Bottle at set point
Lower set point
Thermostat not calling for cooling
Lower set point
Faulty thermostat or wiring

Cellar temperature is too warm
Possible cause
Solution
The temperature of the room to which the condensing unit exhausts
exceeds 110°F
Intake temperature needs to drop below 110°F
The system is undersized for the cellar
Order correctly sized system
There is something blocking the supply and/or return air on the
evaporator units or the condensing unit
Remove air flow obstruction
Evaporator units are mounted too low in the cellar
Relocate units so the distance from the ceiling and top of the units is
no more than 18”
One or more of the fans is not turning on
Please contact the installing technician to troubleshoot
Compressor is not turning on
Please contact the installing technician to troubleshoot
Compressor keeps cycling on overload
Make sure all fans are working and there is no airflow obstruction
Poor seal around door or other areas requiring a seal (around the
evaporator units, wall joints, etc .)
Make sure there are no air gaps around the door . If door seal is
damaged, replace it .
Set point too high
Lower the set point
Evaporator coils are frosted or iced up
Observe ice formation pattern . If only part way up the coil face,
evaporator units could be low on refrigerant . If so, contact your
installing technician to assist with troubleshooting .
System runs constantly
Possible cause
Solution
Leaky door seal or poorly insulated cellar
Fix leaky door seal and insulate cellar
