Why Daikin FUQ100CVEB Air Conditioner operates but it does not sufficiently cool or heat?
- D
  Denise MillerAug 18, 2025
  If your Daikin Air Conditioner is running but not cooling or heating effectively, consider these potential causes: * Obstructions: Check if the air inlet or outlet of either the outdoor or indoor unit is blocked. If so, remove the obstacle to ensure proper ventilation. * Dirty Air Filter: A clogged air filter can restrict airflow. Ask a qualified service person to clean the air filters. * Improper Settings: Make sure the temperature, fan speed, and airflow direction are appropriately set. * Open Doors/Windows: Ensure doors and windows are closed to prevent drafts. * Direct Sunlight: Use curtains or blinds to block direct sunlight, which can affect cooling performance.

How to fix a Daikin FUQ100CVEB that won't turn on?

  martingayAug 26, 2025
  If your Daikin Air Conditioner doesn't turn on at all, first check if a fuse has blown and turn off the power supply. Next, check if the power circuit breaker is blown. If the tab is in the OFF position, turn the power on using the breaker switch. However, if the tab is in the trip position, do not attempt to turn the power on and contact your local dealer. Finally, check for a power failure and wait until power is restored. If a power failure occurred during operation, the air conditioner will automatically restart once the power supply recovers.
