Wrong wire connection
Connect the circuit diagram correctly
Replace the fan motor
Adjust the volume of the refrigerant
Replace the capillary
Replace the compressor
The protector itself has malfunction.
Replace the protector
The protector itself has malfunction.
The fan does not
run when it is set
to supply air.
The compres-
sor is too hot
and leads to the
action of the
protector.
The indoor fan motor is burned or
breaks or has the heat protector
malfunction.
The built-in heat protector of the
motor breaks frequently because the
motor is abnormal.
The fan capacitor has open circuit or
is damaged.
Breakage of running capacitor of
compressor
The voltage is too low or too high.
The refrigerant is not enough or is too
much.
The capillary is blocked and the tem-
perature rises.
The compressor does not run
smoothly or is stuck. The air discharge
valve is damaged
Make the correction connection based on
the circuit drawing.
Replace the fan capacitor of the same type
and same specification.
Make the correct connection based on the
circuit drawing
Use the multimeter to check whether the
contact of the compressor is on when it is
not overheated. If it is not on, then replace
the protector
tioner, using the voltage recorder.
