York Air Conditioning
26 fault codes documented
Abnormal heat in power supply cord or plug
The power cord or the plug feels unusually hot to the touch. This indicates a potential electrical hazard.
Liquid or foreign objects inside the unit or remote
Impurities or water has been accidentally poured into the air conditioner unit or its remote control.
Air conditioner will not operate at all
The air conditioner does not turn on or respond to commands. This could be due to power supply issues or internal faults.
Air switch or protection switch trips frequently
The circuit breaker or protection switch for the air conditioner repeatedly trips or shuts off.
Red Compressor indicator solid, indoor fan stops — Unit is defrosting
During heating operation, if the red compressor indicator lights up constantly and the indoor fan stops, the unit is automatically shifting into defrost mode to maintain efficiency. This is a normal operation, not a malfunction.
Cooling or heating efficiency is poor
The air conditioner is not cooling or heating the space as effectively as it should.
Cracking sound from the unit
A cracking sound might be heard from the air conditioner. This sound is typically caused by the expansion or contraction of the unit's plastic components, such as the front panel, due to changes in temperature, and is a normal occurrence.
Unit does not run or operate
The air conditioner unit is not starting or running. This could be due to a tripped protector, a blown fuse, low remote control batteries, or an improperly connected power plug.
E1 Error Code — Room temperature sensor fault
The room temperature sensor is not functioning correctly. This can affect the accuracy of temperature readings and the unit's operation.
E2 Error Code — Outdoor coil temperature sensor fault
The outdoor coil temperature sensor is malfunctioning. This sensor is crucial for regulating the cooling or heating process.
E3 Error Code — Indoor coil temperature sensor fault
The indoor coil temperature sensor is faulty. This can lead to incorrect temperature control and affect the unit's efficiency.
E4 Error Code — Indoor fan motor feedback fault
There is an issue with the indoor fan motor's feedback signal. This indicates a problem with the fan's operation or its communication with the control board.
FC displayed — Filter cleaning reminder
The display shows 'FC' after 200 hours of usage. This is a reminder to clean the air filter.
Indoor unit blows out mist during cooling operation
Mist is sometimes seen coming from the indoor unit outlet during cooling mode. This is usually temporary.
Indoor unit doesn't start immediately after restart
The indoor unit takes a delay of 3 to 5 minutes to start after being turned on again.
Ineffective control or abnormal operation due to interference
The air conditioner's operation becomes abnormal or controls are ineffective due to strong electrical interference, such as static electricity discharge or power supply voltage issues.
No cooling or heating air from the unit
The air conditioner is running but is not effectively cooling or heating the room. This can be caused by dirty air filters, blocked air intakes or outlets, or incorrect temperature settings.
Peculiar odor from the air conditioner
A strange smell might be emitted from the unit. This is often not a malfunction of the air conditioner itself but rather odors from the surrounding environment (like furniture or cigarette smoke) that are sucked into the unit and blown out with the air.
Remote controller is not working or available
The remote controller is unresponsive or cannot communicate with the indoor unit.
Running indicator flashes — Unit is defrosting
The Running indicator on the indoor unit flashes when the appliance is in defrosting mode during heating operation. This is a normal part of the heating cycle to improve efficiency.
Shrill sound or unpleasant odor during operation
A very loud, shrill noise or a strong unpleasant smell is emitted while the unit is running. This requires immediate attention.
Slight 'click' sound during start-up or shut-down
A small clicking sound is heard when the unit starts or turns off. This is normal.
Sound of flowing water from the unit
You may hear a sound resembling flowing water from the air conditioner. This is a normal sound caused by the circulation of refrigerant within the system and indicates proper operation, not a fault.
Sound of running water during operation
A 'hissing' sound like running water is audible while the air conditioner is running. This is normal.
Spray mist appears from the air outlet during COOLING or DRY mode
During COOLING or DRY operation, a fine mist may be visible coming from the air outlet. This occurs when the room air becomes very cold due to the cool air discharged from the indoor unit, causing condensation to become visible. This is not a malfunction.
Unusual smell from the air outlet
An unpleasant odor is coming from the air conditioner's outlet after it begins operating.
