LG Air Conditioner CH10 error code

Difficulty: Medium · Cost: $0–$150 · Duration: 10–15m

The CH10 error means your LG air conditioner's indoor unit fan has stopped working correctly. The indoor fan is responsible for drawing warm air from the room across the cooling coil and circulating conditioned air back out. When it cannot spin properly the unit stops running to prevent damage. This code may also appear as E6 on some models. The most common cause is a physical obstruction blocking the fan. If no blockage is found the fan motor will need to be inspected by a technician.

Common causes

Debris, dust buildup, or a foreign object blocking the indoor fan blades
Indoor fan motor has malfunctioned or failed
Wiring fault affecting the indoor fan motor
Fan blade is cracked or damaged causing it to jam
