    Why is my Daikin FWD04ACFN6V3 Air Conditioner not cooling well?

      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”).
