What to do if my LG Air Conditioner is running but not cooling?
- RRobert AustinAug 1, 2025
If your LG Air Conditioner is running but not cooling effectively, several factors could be the cause. You should check the heat load rise during cooling operation, ensure smooth cold (warm) air circulation, and inspect the outdoor coil (heat exchanger) and fan operation. Also, check for gas leakage, a dirty indoor coil (heat exchanger), added electrical utensils, or a malfunction of the fan or compressor. Other potential issues include a clogged air filter, obstruction at the air outlet, or the stop of auto air-swing. Also, check inside gas pressure and clogging in the refrigeration circuit. Depending on the issue, you may need to repair a gas leak or clogging in the refrigeration circuit, adjust the refrigerant charge, or consider unit replacement if the damage is beyond repair.
