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
