2.7 High discharge/compressor-top temperature protection
Code displayed:
ODU main board displays E003/E027 (applicable to AS/AX models) or
E036 (applicable to AA models).
Fault detection method:
Measure compressor discharge temperature and
compressor-top temperature through temperature sensor.
Fault identification conditions:
when detecting the following temperatures beyond set
range.
①
Temperature of discharge pipe of compressor
②
Temperature at the top of compressor
Possible causes:
①
Temperature sensor fails
②
Check valve and electronic expansion valve abnormal
③
Insufficient refrigerant
④
Ports of master control board fail
⑤
Compressor exception
⑥
Abnormal fan
NO
YES
YES
Whether
normal
NO
Check IDU and ODU operating status:
①
Whether readings of temperature sensor are correct (replace sensor)
②
Check valve and electronic expansion valve exception (valve not opened, or pipe blocked)
③
Insufficient refrigerant (high/low pressure is low under full load operation and IDU is not working
properly)
④
Ports of master control board fail (check to make sure that the voltage at the ports is within
specified range)
⑤
Whether heat exchanger removes enough generated heat and whether fan works normally
Repair

and
restart the unit
Reset the unit to see
whether the unit works
properly
Normal use
Replace compressor
