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. 

Cut-in too high 

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. Reduce 

Hy 

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

Call service for diagnosis 

2. Unit not 

starting , but 
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 cycle) and turns off at 55

°

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.  Short circuit of air flow between 

cold-air supply and return-air 
intake, displaying temperature 
ok 

c.  Failed controller and probe 

a.  Move the air probe away from the 

evaporator 

 
b.  Deflect the supply air down 
 
 
 
c.  Call service for diagnosis 

6. Temperature 

a.  Improper  cabinet  insulation  &  a.  Check insulation, gasket and door
