  Ian MartinAug 3, 2025
  There are several reasons why your Mainstays air conditioner might not be cooling effectively. It could be due to a dirty air filter, which needs cleaning or replacing. The unit size might be inappropriate for the room, or there could be blocked airflow from obstructions. Another cause can be a power interruption, settings changed too quickly, or a tripped compressor overload. In the last case, turn the unit off and wait 5 minutes before attempting to restart.

  If your Mainstays air conditioner isn't turning on, first, ensure the power cord is properly connected to the power source. Then, check the fuse or circuit breaker. Also, make sure the selector switch is set to a position other than 'OFF', and that the 'RESET' button on the power cord is pushed in.

  If you notice water dripping inside your Mainstays air conditioner, it could be that the unit isn't properly angled to allow water to drain outside. Check the unit's angle and adjust as necessary. Also, on extremely humid days, some dripping is expected, so no action is required.
