Why is my Kaysun KAM2-42 DR7 not cooling well?
- K
  Kevin AndersonAug 12, 2025
  Several factors can cause poor cooling performance in your Kaysun Air Conditioner. The temperature setting might be higher than the room temperature; try lowering it. The heat exchanger or air filter could be dirty—clean them as instructed. Make sure that the air inlet or outlet isn't blocked. Also, ensure doors and windows are closed, and reduce excessive heat by closing curtains. Finally, low refrigerant levels due to leaks or long-term use can be a factor; check for leaks and top off the refrigerant if needed.

  If your Kaysun Air Conditioner isn't working, first, check for a power failure and wait for the power to be restored. Ensure the power switch is turned on and replace the fuse if it's burned out. Replace the remote control batteries if they are dead. Also, the unit's 3-minute protection might be activated; wait three minutes after restarting the unit.

Why does my Kaysun KAM2-42 DR7 Air Conditioner start and stop frequently?
- N
  Nathan JuarezAug 27, 2025
  Frequent starting and stopping of your Kaysun Air Conditioner can be due to several reasons. There might be too much or too little refrigerant in the system, so check for leaks and recharge the system. Another cause could be air, incompressible gas, or foreign material in the refrigeration system, requiring evacuation and recharge. A blocked system circuit or a broken compressor could also be the reason, needing replacement of the malfunctioning part. Lastly, unstable voltage could be the cause; consider installing a manostat to regulate it.

Why is my Kaysun KAM2-42 DR7's heating performance poor?
- D
  davidwandaSep 2, 2025
  Poor heating performance in your Kaysun Air Conditioner can occur if the outdoor temperature is below 7ºC (44.5ºF). Ensure all doors and windows are closed to prevent cold air from entering. Low refrigerant levels due to leaks or long-term use can also cause this issue; check for leaks and add refrigerant as needed.
