alarm
Possible Causes
fan current contactor impassability check contactor coil, replace it if
fan motor protection is open
leakage of freon circuit
lack of freon
temperature controller does not
work or setting error
too big thermal load
The compressor working poor
blockage of freon filter
lack of freon
abnormal temperature expansion
valve
airflow problem
lack of freon
blockage of refrigerant system fil-
ter
Pipeline vibration
Compressor's noise
Expansion valve is sputtering
The connection part of unit struc-
ture loose,cause clash for shaking.
impact or friction between moving
parts and other components
Improper installation of door plank correct installation
Friction of fan impeller and tuyere
Oil shortage or wear of fan bearing fill oil or replace
the connecting bolt of fan is loose
Compressor still work after reach-
ing a certain temperature: there is
something wrong with the tem-
perature
The heater doesn't work: The
heating resistance is without elec-
tricity or under voltage
The heater doesn't
work:resistance burned
The heater doesn't work:the tem-
perature probe problem
