Why does my Kaysun Air Conditioner not turn on?
- B
  Brenda ArroyoAug 17, 2025
  Your Kaysun air conditioner might not be turning on due to a few reasons. Firstly, it could be due to the 3-minute protection feature that prevents overloading; the unit cannot be restarted within three minutes of being turned off, so wait for three minutes before trying again. Secondly, if you have a cooling and heating model, the outdoor temperature might be too cold, activating the anti-cold wind feature to defrost the unit; wait for it to defrost. Lastly, in cooling-only models, the anti-freeze protection might be activated for defrosting if the outdoor temperature is too cold; again, wait for the unit to defrost.

What to do if my Kaysun KCIS-71 DR11 Air Conditioner changes from COOL to FAN mode?
- M
  Michael ScottAug 20, 2025
  If your Kaysun air conditioner switches from COOL to FAN mode, it could be preventing frost buildup. Allow the temperature to increase so the unit can resume normal operation. Alternatively, the set temperature may have been reached, causing the compressor to turn off. Adjust the set temperature to prevent this.

Why does my Kaysun KCIS-71 DR11 Air Conditioner emit a bad odour?
- A
  Ashley AndersonAug 22, 2025
  Your Kaysun air conditioner might be emitting a bad odor because it has absorbed smells from the environment, such as furniture, cooking, or cigarettes. This is normal. However, it could also be due to moldy filters, in which case you should clean them.

Why does my Kaysun KCIS-71 DR11 Air Conditioner make noises?
- J
  Jessica CurryAug 26, 2025
  If your Kaysun air conditioner is making squeaking sounds when off or in COOL mode, or when the drain pump is operating (if equipped), this is normal. A squeaking sound might also occur after running the unit in HEAT mode due to the expansion and contraction of the unit's plastic parts, which is also normal.

Why does my Kaysun KCIS-71 DR11 Air Conditioner emit white mist?
- T
  Tricia JohnsonAug 28, 2025
  If your Kaysun air conditioner is emitting white mist, especially in humid regions, it's likely due to a large temperature difference between the room's air and the conditioned air. This is a normal occurrence.

Why is my Kaysun Air Conditioner emitting white mist from both indoor and outdoor units?
- M
  Manuel LeeAug 30, 2025
  If both the indoor and outdoor units of your Kaysun air conditioner are emitting white mist, it's likely because the unit restarted in HEAT mode after defrosting. The mist is due to moisture generated during the defrosting process, and this is a normal occurrence.

Why do my Kaysun KCIS-71 DR11 indoor and outdoor units make noises?
- M
  munozchristinaSep 2, 2025
  A low hissing sound may occur during operation of your Kaysun air conditioner. This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units. Also, a low hissing sound may be heard when the system starts, has just stopped running, or is defrosting. This noise is normal and is caused by the refrigerant gas stopping or changing direction.
