Koppel AC Troubleshooting
Malfunction: The appliance does not operate
- Power failure/plug pulled out
- Damaged indoor/outdoor unit fan motor
- Faulty compressor thermomagnetic circuit breaker
- Faulty protective device or fuses.
- Loose connections or plug pulled out
- It sometimes stops operating to protect the appliance.
- Voltage higher or lower than the voltage range
- Active TIMER-ON function
- Damaged electronic control board
Malfunction: Strange odour
Possible Causes: Air filter dirty
Malfunction: Noise of running water
Possible Causes: Back flow of liquid in the refrigerant circulation
Malfunction: A fine mist comes from the air outlet
Possible Causes: This occurs when the air in the room becomes very cold, for example in the COOLING or DEHUMIDIFYING/DRY modes
Malfunction: A strange noise can be heard
Possible Causes: This noise is made by the expansion or contraction of the front panel due to variations in temperature and does not indicate a problem.
Malfunction: Insufficient airflow, either hot or cold
- Inappropriate temperature setting..
- Air inlet or outlet of indoor or outdoor unit has been blocked.
- Air filter is blocked.
- Fan speed set at minimum.
- Other sources of heat in the room.
- No refrigerant
Malfunction: The appliance does not respond to commands
