    Why is my Daikin FWD18ACFN6V3 not cooling well?
    • K
      Kelly SmithAug 9, 2025
      Poor cooling or heating performance in your Daikin Air Conditioner can stem from several causes: a dirty or clogged air filter (clean it), an obstacle near the air inlet or outlet (remove it), open doors or windows (close them), or the unit running at low speed (select medium or high fan speed). Also, air inside the heat exchanger can affect performance, so you may need to contact the installer.

      If your Daikin Air Conditioner isn't turning on, the issue might be a power failure (restore power), a tripped automatic circuit breaker (contact service center), or the switch being in the STOP position (turn the unit ON by selecting “I”).

      If your Daikin Air Conditioner is leaking, it could be due to incorrect installation, specifically the unit not being installed with the correct inclination, or a clogged condensate discharge. In both cases, it's best to contact the installer for assistance.
