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
, 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
° F
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
