Why is my LG Packaged Terminal Air Conditioner running but not cooling?

  If your LG Air Conditioner is running but not cooling effectively, several factors could be the cause. Start by checking for any increase in heat load and ensure cold air circulation is smooth. Inspect the outdoor coil (heat exchanger) and fan operation. Also, check for gas leakage and ensure the indoor coil (heat exchanger) is clean. Other potential issues include an overloaded circuit, a malfunctioning fan or compressor, a clogged air filter, or an obstruction at the air outlet. If there is gas leakage, repair it. If the unit is beyond repair, consider a replacement. Note that satisfactory operation should have a temperature difference of 44.6~50°F (7~10°C) between inlet and outlet air.

  If your LG Air Conditioner fails to start, begin by checking the power source, circuit breaker, and fuse. Then, inspect the control switch and thermostat setting, ensuring it's properly set. Other potential issues include gas leakage from the thermostat's feeler bulb, improper wiring, or a drop in power voltage. If only the compressor or fan fails to start, it could be due to a defect in the fan motor or compressor capacitor. Also, check for loose terminal connections, irregular motor resistance or insulation, and check the capacitor. Replacement of the fan motor or compressor (due to locking of rotor, metal fatigue, or motor damage) may be necessary.

Why does my LG Packaged Terminal fan motor make noise?

  To address fan motor noise in your LG Air Conditioner, check the grommets and replace them if they are worn or missing. If the fan or turbo fan is cracked, out of balance, or partially missing, replace it. Tighten any loose set screws. If knocking sounds continue when running or the bearings are loose, replace the motor. Also, if the motor hums or the noise appears internal while running, replace the motor.

  If the fan motor of your LG Air Conditioner runs intermittently, check the voltage against the specified limits. If it's not within limits, consult an electrician. Test the capacitor and check the bearings. Ensure the fan blade rotates freely; if not, replace the fan motor. Pay attention to any change from high speed to low speed; if the speed does not change, replace the motor.
