User’s  Troubleshooting 

This Troubleshooting Chart is not prepared to replace the training required for a 
professional refrigeration service person, not is it comprehensive. 

 

Complaint 

Possible Causes 

Response 

1. Unit not running 

Power cord not plugged 
No power from supply 
Incorrect or loose wirings 
Low voltage 
Setting higher  than 

ambient 

temperature 
Waiting for cut-in 
Defrost light blinking 
Compressor light blinking 
Defective controller 

Check power cord 
Check receptacle and fuses 
Check all wirings and connections 
Contact an authorized electrician 
Lower temperature setting 
 
Wait 
Unit is under defrost mode 
Unit is under anti-short cycle delay 
Call service for diagnosis 

2. Unit not starting 
and temperature 
rising high 

a. Anti-short cycle 

a. Reset AC 

3. Temperature 
fluctuating 

a. Air probe 

a. When using an air probe, the wine 
bottle temperature is mainly 
controlled by the average air 
temperature. If the set-point is 55

°

with the differential 4F, the cooling 
unit turns on at 59

°

F of air 

temperature (It may be higher than 
59

°

F if it is in anti-short cycle or 

defrost) and turns off at 55

°

F of air 

temperature. The average air 
temperature is 57

°

F, and then the 

wine temperature is around 57+/- 
0.5

°

F. The air is light enough to 

change so quickly that it maintains 
relatively  constant  average 
temperature that would prevent wine 
bottle temperature from fluctuating. 

4. Temperature 
high, unit stopping 
and starting 
normally 

a.   Temperature setting high 

a.   Lower the setting 

5. Temperature 
high, unit stopping 
and starting with 
short running 
time 

Air probe touching  the evaporator 
coil, displaying temperature ok 
Air probe in cold-air supply, 
displaying temperature ok 
Failed controller and probe 

Move  the  air  probe  away  from  the 
evaporator 
 
Move  the  air  probe  away  from  the 
cold-air supply 
Call service for diagnosis 

6. Temperature 
high or not cooling 
and running 
continually 

Improper cellar insulation & seal 
 
Cellar too large 
Malfunctioning fans 
Evaporator airflow 

Check  insulation,  gasket  and  door 
opening 
Check for excessive size 
Check for evaporator fans 
Check  for  air  restrictions,  air  short- 
circulation, grille directions
