Why is my Daikin FDXM50F3V1B Air Conditioner not cooling enough?
- T
  Tanya GarciaAug 8, 2025
  If your Daikin Air Conditioner isn't cooling or heating sufficiently, ensure that the air inlet or outlet of the outdoor or indoor unit isn't blocked by any objects. Clear any obstructions to allow free airflow. Also, ensure doors and windows are closed to prevent drafts, and use curtains or blinds to block direct sunlight. Note that cooling may be less effective if there are too many people in the room or excessive heat sources.

  If your Daikin Air Conditioner operation stops suddenly and the operation lamp is blinking, first check if the air filter is clogged and contact your dealer to clean it. Next, check if the air inlet or outlet of the outdoor or indoor unit is blocked by obstacles, and remove any obstructions. Then, turn the breaker OFF and back ON. If the lamp continues to blink, contact your dealer. Also, check if all indoor units connected to the outdoor unit in the multi-system are operating in the same mode.

  If your Daikin Air Conditioner system isn't operating, first check for a power outage and wait for the power to be restored. In case of a power failure during operation, the system will automatically restart once power returns. Also, check if a fuse has blown or a breaker has tripped; replace the fuse or reset the breaker if needed. Finally, verify that the batteries are properly installed in the remote controller and that the timer is correctly set.
