empty unit (assuming ambient temp of 32 degrees centigrade and continuous operation). If not, check the
compressor, cooling fans, controller, and sensors. If all these are working normally, there is probably a
cooling pipe fault.
7.1. Check the compressor
If the wine cooler not cooling, check the current with the Amp meter，refer to rating label, if it too
high or too low, cut the discharge pipe
(Fig. 17 item F)
and
(Fig.12 item B)
, power on, check the
current, and feel the discharge pipe, if the obvious air pressure from compressor, if the current still
very high or very low or the discharge pipe with small air pressure, the compressor fault, replace
the compressor please.
Notice. After cut the discharge pipe and process pipe, in case of suck the damp, the compressor
should ne power on long time (no exceed 15 minutes is best).
7.2. Check the cooling system
When it is sure that the compressor is working normally and the cooling system’s fault is concentrating on
the cooling system pipe. Check following below:
1>.
Cut off process pipe and check the refrigerant. If there is not enough refrigerant, the default of the
refrigerant system should be caused by the leaking. If the refrigerant is sufficient., it is probably
block in the capillary.
2>.
If the default is concentrated on the cooling system, the checking procedure is as below.
a.
Cut off the discharge pipe
(See Fig.17 item F)
of the compressor, and infuse 0.8-1.5 MP
nitrogen per process pipe, and put the hand close to the cut kerf. If there is a little gas leak
from the terminal, it means normal, otherwise it is jammed.
b .
Make sure the capillary is working normally. Then reconnect the discharge pipe, and infuse
0.8-1.5 MP nitrogen from process pipe, then test the leakage
, check with soap water if
the
cooling system of the soldering point is damaged. Check from the soldering points around
the compressor
(Fig.17)
, if it is OK, then check the soldering point of the evaporator
(Fig.7 )
,
before check please remove the air-duct board, please see the remove method and procedure
