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 

a.  Power cord not plugged 
b.  No power from supply 
c.  Incorrect or loose wirings 
d.  Low voltage 
e.  Setting  higher  than

ambient temperature 

f. 

Waiting for cut-in 

g.  Defrost light blinking 
h.  Compressor light blinking 
i. 

Defective controller 

a.  Check power cord 
b.  Check receptacle and fuses 
c.  Check all wirings and connections 
d.  Contact an authorized electrician 
e.  Lower temperature setting 

 

f. 

Wait 

g.  Unit is under defrost mode 
h.  Unit is under anti-short cycle delay 
i. 

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 

a.  Air 

probe 

touching 

the 

evaporator 

coil, 

displaying 

temperature ok 

b.  Air  probe  in  cold-air  supply, 

displaying temperature ok 

c.  Failed controller and probe 

a.  Move  the  air  probe  away  from 

the evaporator 

 

b.  Move  the  air  probe  away  from 

the cold-air supply 

c.  Call service for diagnosis 

6. Temperature 

high or not 
cooling and 
running 
continually 

a.  Improper cellar insulation & 

seal 

 

b.  Cellar too large 
c.  Malfunctioning fans 
d.  Evaporator airflow 

a.  Check  insulation,  gasket  and 

door opening 

b.  Check for excessive size 
c.  Check for evaporator fans 
d.  Check  for  air  restrictions,  air 

short- circulation, grille directions
