Troubleshooting Chart 
 
Complaint Possible 
Causes 
Response 
1.Unit not 
running
 
a. No 
power 
b.  Power cord unplugged 
c. Setting higher than ambient 
temperature 
d. Defrost 
light 
blinking 
e.  Compressor light blinking 
f. Low 
voltage. 
g.  Incorrect or loose wirings. 
 
a.  Check power at receptacle & fuses 
b.  Check for power cord plug 
c. Lower 
temperature 
setting 
 
d.  Unit is under defrost mode 
e.  Unit waits for anti-short cycle delay 
f. 
Contact an authorized electrician  
g.  Check all wirings and connections 
 
2.Temperature 
fluctuating
 
a. Air sensor  
When using an air sensor, the wine 
bottle temperature is mainly controlled 
by the average air temperature. If the 
set-point is 55
°
F with a differential 4
 °
F, 
the cooling unit turns on at 59
°
F of air 
temperature 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 varying. 
3.Temperature 
too high,  
Unit stopping 
and starting 
but short 
running time
 
a. Displaying  55
°
F, air sensor 
contacting the evaporator or in 
the supply air 
b.  Setting too high 
c. Incorrect 
voltage 
d. Failed 
thermistor 
 
e. Failed 
components 
 
f. Improper 
condenser 
airflow 
g. Dirty 
condenser 
h.  Overcharge of refrigerant 
i.  Discharge or suction pressure 
too high 
 
a.  Move the air sensor away from the 
evaporator and supply air 
 
b. Lower 
setting 
c.  Check for voltage 
d.  Check thermistor by placing it in ice 
water and measuring resistance 
e.  Check compressor windings, start 
relay and overload protector. 
f. 
Check for condenser fan  
g. Clean 
condenser 
h.  Call service for removing refrigerant 
i. 
Call service for OEM information 
 
4.Not cooling 
or 
Temperature 
too high and 
running 
continually   
a.  Improper room insulation & seal 
 
b.  Room too large 
c.  Ambient temperature too high 
d.  Exhaust restricted  
 
 
a.  Check for insulation, gasket and 
door opening 
b.  Check for excessive size   
c.  Check for installation location 
d.  Leave minimum 3 feet clearance for 
the exhaust side and leave minimum 
1 foot clearance for the fresh air
