Possible Causes

 

 

Response

 

1.Unit not

Power cord unplugged

 

a.

Check for power cord plug

Decrease the value as to 4 °F

 

d.

Differential too high

 

d.

 

e.

Incorrect or loose wirings

e.

Check all wirings and connections

 

f.

Low voltage

 

f.

Contact an authorized electrician

 

g.

Defrost light blinking

 

g.

Unit is under defrost mode

Compressor light blinking

h.

Unit waits for anti-short cycle delay

2.Fan running

3.Temperature

a.

Air sensor

 

a. When using an air sensor, the wine

fluctuating

 

 

 

 

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 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.

 

 

 

 

 

4.Temperature
