3 Failure in operation
Symptom
Power supply not available
The power supply is available but startup
is impossible
The switches are all normal but startup
is impossible
4 Adverse situation after startup
Symptom
Abnormal voltage
The tripped high-pressure switch has
been reset but startup is impossible
Tripped overload relay
AE5881/AE5882/AE5883
Cause
Blown fuse or tripped residual current circuit
breaker
Broken wire
Abnormal voltage or too long power cable
(voltage drop)
Faulty switch
Faulty contactor
Overloaded relay
Faulty capacitor
Faulty starter relay
Faulty high/low pressure switch
Faulty temperature switch
Faulty compressor
The tripped high/low pressure switch is not
reset
The tripped electromagnetic switch O.L is not
reset
The oil pressure switch is not reset
Error in temperature switch setting
Faulty compressor
Cause
Shortly after startup, the wire is short-circuited
to produce the smell of burning
Faulty pressure switch
Faulty fan
Overload trip
Condenser dirt
Too much refrigerant
Too high ambient temperature
Expansion valve blocked or closed
Dryer filter blocked
Faulty starter relay
Faulty capacitor
Pressure Switch
Compressor overload
Too high temperature at the dryer inlet
Too high ambient temperature
The set current value of relay is too low
Poor contact of relay
Phase loss of power supply
Contactor failure or poor contact

Refer to the rated voltage indicated on the
nameplate
Replace the switch
Replace the contactor
Replace the relay
Replace the capacitor
Replace the starter relay
Replace the high/low pressure switch
Replace the temperature switch
Replace the compressor
Locate the cause of trip, and then reset the
switch
Locate the cause of trip, and then reset the
switch
Locate the cause, and then reset the switch
Reset or replace the temperature switch
Replace the compressor
Troubleshooting
Check the voltage and circuit
Replace the pressure switch
Replace the fan motor with a new one
Locate the cause or check the relay
Cleaning
Properly reduce the refrigerant
Improve the ambient temperature or choose a
well ventilated area
Replace the expansion valve
Replace the dryer filter
Replace the starter relay
Replace the capacitor with a new one
Replace the pressure switch
Overload the dryer and reduce air volume
Install a pre-cooler
Improve the ambient temperature or choose a
well ventilated area
Adjust the current value
Replace the relay
Locate the cause of phase loss of power
supply
Replace the contactor
