Refrigerant jet noise
Fault: a continuous noise like a water spray from the capillary.
Causation: the end of the capillary is in the wrong position, or there are rough edges on the end of the
capillary.
Solution :
1>. Heat the soldered joint of the capillary (Fig.3 showing A point) , then remove the capillary from the
evaporator and smooth the end with an eraser. (Caution: do not allow any particles into capillary unit).
2>. Replace the capillary into the evaporator, then solder it back into the correct position (not exceeding
15mm in the evaporator) and pack the joint with anti vibration compound.
3>. Vacuumize and recharge with refrigerant. See (

Capillary vibration noise
Fault: high frequency impact noise in capillary Zone. Caused by either
Causation:
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.
Solution:
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 or the air duct panel, adjust the position of the capillary and add
the incabloc plastic. (Fig.3)

Oil jam noise
Fault: intermittent and deep jet noise coming from inside of the capillary.
Causation: Compressor oil flowing into the cooling system pipe work probably due to the unit leaning during
