Why is my Kaysun KUE-52 DVN10 not working?
- JJohn NealAug 12, 2025
Your Kaysun Air Conditioner might not be working due to several reasons: a power failure (wait for the power to be restored), the power switch being off (turn the power on), a burned-out fuse (replace the fuse), dead remote control batteries (replace the batteries), or the unit's 3-minute protection being activated (wait three minutes after restarting the unit).
