）
Check the input wire (white color) of compressor with ammeter, if current is triple times or
above than rated current, it can be judged as the rotor within the compressor not working.
4
）
Under refrigeration status, the compressor can work.
4.1
）
Observe the refrigeration piping (as picture) whether there is oil tracking or frosting, such as oil
or frost phenomenon, can be judged refrigerant leakage (such as inside the condenser or evaporator
internal pipe line leakage refrigerant).
Solution:
Have some air-conditioning maintenance people to locate the leakage parts
,
refill the holes
of leakage, and then fill the refrigerant.( The mode and capacity of refrigerant can be view from the
label of machine)
4.2
）
Check the capacity of boost capacitor of compressor with testing tools (as picture), the standard
capacity figure is 10%, if the figure below 10% can be judged the compressor boost capacitor
lower lead to refrigeration capacity low.
Solution:
Replace capacitor of compressor
.
