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

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.

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 cycle) 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

c. Failed controller and probe
a. Move the air probe away from the
evaporator
