Solution
Correct the installation position to prevent the air
intake and output from clogging.
If excessive gas has been loaded, recover the
refrigerant and then reload the required mass.
Make sure that the power supply voltage is cor-
rect (230V).
If the same error code appears again, replace the
PCB MAIN.
Disconnect and reconnect the power supply.
The COMPRESSOR must be replaced.
Replace the PCB MAIN board.
Correct the installation position to prevent the air
intake and output from clogging.
If excessive gas has been loaded, recover the
refrigerant and then reload the required mass.
Make sure that the power supply voltage is cor-
rect (230V).
Disconnect and reconnect the power supply.
Correct the installation position to prevent the air
intake and output from clogging.
If excessive gas has been loaded, recover the
refrigerant and then reload the required mass.
Make sure that the power supply voltage is cor-
rect (230V).
If fuse CF6 is blown, replace the PCB MAIN.
If fuse CF2 is blown, replace the PCB MAIN.
Disconnect and reconnect the power supply.
Remove the obstruction and resume operation.
The COMPRESSOR must be replaced.
Replace the sensor if it is faulty.
Replace the sensor if it is faulty.
