Why is my Daikin FHYB100FV1 Air Conditioner not cooling or heating sufficiently?

  Stephanie CollierAug 8, 2025
  If your Daikin Air Conditioner isn't cooling or heating enough, several factors could be at play. Check for obstructions blocking air inlets or outlets and ensure they are well-ventilated. Consider having a qualified service person clean the air filters. Make sure the set temperature and fan speed are properly adjusted. Ensure the airflow angle is correct. Close any open doors or windows to prevent drafts and use curtains or blinds to block direct sunlight. Be aware that too many people or excessive heat sources in the room can also reduce cooling effectiveness.

  If your Daikin Air Conditioner system stops operating after it has already started, it could be due to obstacles blocking the air inlet or outlet. Remove any obstructions to ensure proper ventilation. Alternatively, the air filter might be clogged. In this case, ask a qualified service person to clean the air filters.

  Deanna Obrien DVMAug 27, 2025
  If your Daikin Air Conditioner system isn't operating at all, it could be due to a power failure. In this case, wait until the power is restored, as the system should automatically restart. Another cause might be a blown fuse, so turn off the power supply. Finally, check if the breaker is in the trip position; if so, do not attempt to turn the power on and contact your dealer.
