Capillary vibration noise
Default: high frequency impact noise in capillary Zone.
Caused by either:
1>. The capillary being insert too deep into the evaporator, so when the refrigerant is Jetting, the end of
vibrating capillary will hit the inside of the evaporator.
2>. Vibration from the capillary touching the inside of the cabinet or air duct board, then when refrigerant is
jetting.
Solutions:
1>. If the capillary is inserted too deep, heat it with the solder, solder it again(Please noted, the deep inserted is not
bigger than 15mm), and vacuumize it and add the refrigerant.

2>. If the capillary touch the inner cabinet and the air duct panel, adjust the position of the capillary and add the
incabloc plastic.

Oil jammed noise
Fault: intermittent and deep jet noise coming from inside of the capillary.
Caused by: Compressor oil flowing into the cooling system pipe work because of wine cooler lean during
transportation, and the jetting oil in the capillary cause noise.
Solutions:
Clean the cooling system pipe, and recharge with refrigerant see

Evaporator freezing.
○
Because the gasket is not air-proof, or the door is not closed well, cause much water fill in the the
cabinet, and the water got frozen when it encounter the cold air, sometimes the ice is too thick,
and it will block the fan or broken the fan.
The solution:
1>. Replace the door gasket or close the door well. If the door gasket is slightly not air-proof, it can be
repaired by the heat dryer.
Aiming at the distortion of the gasket with the heat dryer, and move up and down until it expand
to the normal state. When it is cool, check it with the door closed, if there is any distortion, dry it
again until it fix for the door.
