  If your LG Air Conditioner has no power, try the following: * Check the voltage at the outlet and correct it if there is none. * Check the voltage to the rotary switch. If there's no voltage, inspect the power supply cord and replace it if the circuit is open. * Check the switch continuity, referring to the wiring diagram for terminal identification. Replace the switch if it's defective. * Connect any loose wires, consulting the wiring diagram for terminal identification. Repair or replace any loose terminals.

What to do if the compressor won't run on my LG LP090HED1, but the fan motor does?

  If the compressor of your LG Air Conditioner isn't running while the fan motor is, there are several potential causes and solutions: * **Thermostat:** Ensure the thermostat knob is set to the coldest setting. If it's not, adjust it and restart the unit. Also, check the thermostat's continuity; replace it if the circuit is open. * **Capacitor:** Inspect the capacitor and replace it if it falls outside ±10% of the manufacturer's rating or if it's shorted, open, or damaged. * **Compressor:** Examine the compressor for open circuits or grounding. Replace the compressor if either condition is present. * **Overload:** Check the compressor overload (if it's externally mounted). Replace it if it's open. If the compressor is hot, cool the overload before retesting.

  If the fan motor on your LG Air Conditioner runs intermittently, consider the following: 1. **Voltage:** Check the voltage and ensure it's within the specified limits. If not, consult an electrician. 2. **Capacitor and Bearings:** Test the capacitor and inspect the bearings. Confirm that the fan blade rotates freely; if not, replace the fan motor. 3. **Fan Blade Alignment:** If the fan blade is hitting the shroud or the cross flow fan is hitting the scroll, realign the assembly. 4. **Slinger Ring Condenser Fans:** For units using slinger ring condenser fans hitting the base, shim up the bottom of the fan motor with mounting screw(s). 5. **Motor Shaft Rotation:** Check the fan motor bearings; if the motor shaft won't rotate, replace the motor. 6. **Speed Changes:** Observe any change...
