Notes:
1. How to check whether the compressor is short circuit
①
:
The normal resistance value of inverter compressor among U V W is 0.7~1.5
Ω
, and infinity to earth. If the
resistance value is out of the range, the compressor is abnormal.
2. How to check whether the fan motor is short circuit
②
:
The normal value of DC fan motor coil among U V W is less than 10
Ω
, and the value of AC fan motor coil is
from a few ohm to hundreds of ohm for different fan motor model. If the measured value is 0
Ω
, the fan motor is
short circuit.
3. How to check whether the inverter module is output error
③
:
Dial the multimeter to diode file, black pen on P and red pen respectively on U,V,W, if the multimeter displays
0.4~0.7 V, it is normal; Red pen on N, black pen respectively on U,V,W, if the multimeter displays 0.4~0.7 V, it
is normal. Satisfying the above two conditions at the same time indicates that the inverter module has no
problem.
E8: Outdoor unit address is wrong
E9: EEprom error
E8: Outdoor unit address is wrong.
The ODU’s address is more than 3 or be set
repeatedly.
Main board is disable.
The addresses should be set
less than 3 and differently.
Replace main board.
No
Yes
No
E9: EEprom error
Check the “ENC1” setting in outdoor PCB board is
correct.
Replace the PCB board.
Set again.
Yes
No
