Why is my Fujitsu CDS25R Air Conditioner cooling or heating poorly?
- S
  Stephanie JohnsonAug 8, 2025
  Several factors can impact the cooling or heating performance of your Fujitsu Air Conditioner. Check if the air filter is dirty, or if the air conditioner’s intake grille or outlet port are blocked. Ensure that the room temperature settings (thermostat) are correctly adjusted and that no windows or doors are open. For cooling, close curtains to block bright sunlight. Also, consider if there are heat-generating appliances or too many people in the room.

  If your Fujitsu Air Conditioner isn't operating, check if there has been a power failure. Also, verify whether a fuse has blown out or a circuit breaker has been tripped. Finally, make sure the timer isn't preventing operation.

Why is the airflow weak or stopping in my Fujitsu CDS25R Air Conditioner?
- M
  Mark HarperAug 20, 2025
  Weak or stopped airflow in your Fujitsu Air Conditioner can occur for several reasons. When heating starts, the fan speed is temporarily very low to allow internal parts to warm up. During heating, if the room temperature exceeds the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at a very low fan speed. The unit will also temporarily stop during the Automatic Defrosting mode, which can last between 2 and 16 minutes. The fan may also operate at very low speed when the unit monitors the room’s temperature, or in monitor AUTO operation.

Why is there noise coming from my Fujitsu Air Conditioner?

  You might hear the sound of water flowing in the air conditioner’s piping during operation and immediately after stopping the unit. A slight squeaking sound might occur due to minute expansion and contraction of the panel caused by temperature changes. During heating, a sizzling sound might be heard occasionally, which is produced by the Automatic Defrosting operation.

Why is mist or steam emitted from my Fujitsu CDS25R?
- S
  Stephen BrownAug 29, 2025
  During cooling, a thin mist may be emitted from the indoor unit due to the sudden cooling of room air, resulting in condensation. During heating, the outdoor unit’s fan may stop, and steam may rise from the unit due to Automatic Defrosting operation.
