What to do if my Kaysun Air Conditioner is not working?
- MMisty OrtizAug 16, 2025
If your Kaysun Air Conditioner isn't working, several factors could be the cause. It could be due to a power failure; in that case, wait for the power to be restored. Ensure that the power is turned on. A burned-out fuse could also be the culprit, so replace the fuse. Check the remote control batteries and replace them if they are dead. Also, the unit has a 3-minute protection feature that prevents the unit from overloading, so wait three minutes after restarting the unit. Finally, the timer might be activated, so turn the timer off.
