If your LG portable air conditioner won’t start, it can be frustrating, especially in the sweltering heat. Possible reasons include power issues, timer settings, or faulty components.
To fix the issue, thoroughly examine and troubleshoot the air conditioner step by step to identify the root cause.

2. Air Conditioner Doesn’t Cool Correctly
A well-functioning air conditioner should cool your space efficiently. When your LG portable air conditioner fails to cool properly, it misses its primary purpose. This issue can result from incorrect settings, improper installation, or an obstructed airflow.
The following steps will help you identify the cause and correct the problem.
How To Fix?
