How to troubleshoot LG Air Conditioner that won't start?
- S
  Sarah WernerAug 15, 2025
  If your LG Air Conditioner isn't starting, ensure it's fully plugged into the outlet. Check your house's fuse or circuit breaker and replace the fuse or reset the breaker if needed. If there was a power failure, turn the mode control to off and wait 3 minutes after power is restored before restarting the unit. Also, check the current interrupter device by pressing the RESET button on the power cord plug. If the reset button won't stay engaged, stop using the air conditioner and contact a service technician.

What to do if LG Air Conditioner does not cool enough?

  Michelle ReyesAug 18, 2025
  If your LG Air Conditioner isn't cooling properly, make sure curtains, blinds, or furniture aren't blocking the front of the unit. Adjust the temperature setting to be lower than the current room temperature. Allow time for the room to cool down after turning the unit on. Ensure cold air isn't escaping through open registers and cold air returns. If the cooling coils are iced up, refer to the 'Air conditioner freezing up' information.

  If your LG Air Conditioner is making noise when cooling, it's likely due to normal air movement sounds. If the noise is too loud, try setting the FAN to a lower setting. Window vibration could also be the cause due to poor installation; refer to the installation instructions or check with the installer.
