Trouble description Analyze and diagnose Remark
1 EEPROM faulty Wrong EEPROM used Non-resumable
3
Compressor overcurrent/
phase sequence wrong
Overcurrent after compressor running or power supply phase
sequence wrong before compressor running.If ir occurs 3 timesin
1 hour,conm the failure, the former twice will not alarm.
Non-resumable
6
High/Low voltage
protection
Phase voltage too high or too low(over 270V last 2 seconds;
below 187V last 2 senconds).If it occurs 3 times in 30 minutes,
conrm the falure.
Non-resumable
8
Proctection of
diacharging temp. too
high
After compressor starts up, if TD is over 120degree, 10 seconds
later compressor stops, if it occurs 3 times in 1 hour, conrm the
failure.
Non-resumable
9 DC fan motor faulty
If it occurs times in 1 hour, conrm the failure, the former twice
will not alarm
Non-resumable
10

16
Lack of refrigerant or
diacharging pipe blocked
If it occurs 3 times in 1 hour, conrm the failure Non-resumable
17
4-way valve converse
abnormal
If it occurs 3 times in 1 hours, conrm the failure. Non-resumable
25
Compressor low current/
current imbalance
between two phase
Low current after compressor running or current imbalance
between two phase after compressor running. If it occurs 3 times
in 1 hour, conrm the failure, the former twice will not alarm.
Non-resumable
42
High pressure switch
abnormal
After compressor running for 3min, if switch is detected
unconnected for 30s, it alarms.If it occurs 3 times in 1 hours,
conrm this failure, or if TCM is over 68degree for 10s for 3 times.
Non-resumable
43
Low pressure switch
abnormal
After compressor running for 3min, if switch is detected
unconnected for 30s, it alarms.If it occurs 3 times in 1 hour,
conrm this failure. If it occurs 3 times in 1 hour,conrm the
failure,but in defrosting or within 6min after defrosting, it will not
alarm.
Non-resumable
Note:
1.The ash times of outdoor mainboard(ECU) LED1(red color) indicates the malfuction code. for example, LED1 ash 3times
, the malfuction code is 3.
2.The ash times or malfuction code of indoor unit can also indicates the malfuction code too,the method to conrm please
refer to the indoor unit manul.
