How to fix an LG VM122C9 NJM1 Air Conditioner that won't turn on?
- T
  Terri TorresAug 16, 2025
  First, verify that the power cord of your LG Air Conditioner is securely plugged into the outlet and that the power isolators are switched on. If the unit still doesn't power on, check the fuse to see if it has exploded, and replace it if necessary. Also, check your circuit breaker to see if it has tripped. If a power failure has occurred, turn off the air conditioner and wait three minutes after the power is restored before turning it back on. Ensure that the batteries in the remote controller are correctly inserted or replace them. Finally, check if the air conditioner was turned off automatically at a preset time and turn it on.

Why is my LG VM122C9 NJM1 Air Conditioner not blowing cold air?
- J
  Julie JohnsonAug 19, 2025
  Several factors can cause your LG Air Conditioner to not blow cold air. Ensure that curtains, blinds, or furniture aren't blocking the front of the unit, restricting airflow. Clean the air filter every two weeks. In summer, select Jet Mode for faster cooling. Seal any ventilation points to prevent cold air from escaping. Set the desired temperature lower than the current room temperature. Avoid using heat generators nearby. Ensure the unit is not in Fan Mode; switch to cooling. Lastly, if the outside temperature is excessively high, the cooling effect might be reduced.

Why does my LG Air Conditioner keep turning off?

  willismichaelAug 22, 2025
  Your LG Air Conditioner might be turning off due to the Timer Function timing out; check the timer settings. Alternatively, a power failure during operation could be the cause. If you have the Auto Restart function enabled, the unit will resume operation several minutes after power is restored.

What to do if my LG Air Conditioner is not working normally?
- D
  David RiddleAug 26, 2025
  If your LG Air Conditioner is not working normally, and you notice burning smells or strange sounds, water leaks (even when humidity is low), a damaged or excessively hot power cable, issues with the circuit breaker, or error codes on the unit, immediately turn off the air conditioner. Then switch OFF, or disconnect the power supply, and contact the service center.

Why is my LG VM122C9 NJM1 not blowing hot air?
- N
  Nicole SchwartzAug 28, 2025
  If your LG Air Conditioner isn't emitting warm air, it could be in Defrosting Mode to remove frost from the coils, which takes about 15 minutes. Also, when Heating Mode starts, the vane may be closed until enough warm air is generated. If the outside temperature is too low, the heating effect may not be sufficient.

Why is my LG Air Conditioner running after I turn it off?
- J
  James DavidsonAug 31, 2025
  If the indoor unit of your LG Air Conditioner continues to operate after being turned off, the Auto Clean function may be running. This feature removes moisture from inside the unit. Allow it to complete, or disable the function if you prefer.

How to get rid of odor from my LG VM122C9 NJM1?
- W
  Whitney BushSep 3, 2025
  Odors, like cigarette smoke, can be absorbed into your LG Air Conditioner and released with airflow. If the smell persists, wash the filter. If this doesn't resolve the issue, contact the service center to clean the heat exchanger.

  If you cannot adjust the fan speed on your LG Air Conditioner, it might be because you have selected the Jet Mode or Auto Operation Mode. In these modes, fan speed adjustment is disabled. Select a different operation mode to regain control over the fan speed.

Why is mist coming from my LG VM122C9 NJM1 Air Conditioner?

  Tamara WalkerSep 12, 2025
  The mist coming from the air outlet of your LG Air Conditioner is due to the cooled air forming mist. This will disappear as the room temperature decreases.
