Why is my Daikin Air Conditioner not cooling or heating properly?
- A
  allenkristaAug 4, 2025
  If your Daikin Air Conditioner isn't cooling or heating enough, several factors could be the cause. First, check for any obstructions blocking the air inlet or outlet of either the outdoor or indoor unit and remove them to ensure proper ventilation. Also, ensure the air filter isn't clogged; if it is, have it cleaned by a qualified service person. Make sure that the set temperature, fan speed, and airflow direction are set correctly. Additionally, close any open doors or windows and use curtains or blinds to block direct sunlight.

How to fix a Daikin FHQ71CAVEB Air Conditioner that won't turn on?

  If your Daikin Air Conditioner isn't turning on, there might be a few reasons. First, check if a fuse has blown and turn off the power supply. Next, see if the power circuit breaker has tripped; if it's in the OFF position, switch it back on, but if it's in the trip position, contact your local dealer. Also, verify if there's a power outage, and if so, wait for the power to be restored. Note that the air conditioner will automatically restart after a power failure.

Also, verify if any remote control device is connected, and contact the central control room that directed the stop.
