  Several factors can cause poor cooling performance in your Deye Air Conditioner. The temperature setting might be higher than the room temperature; try lowering it. The heat exchanger or air filter could be dirty, requiring cleaning. Obstructions in the air inlet or outlet should be removed after turning the unit off. Ensure doors and windows are closed to prevent heat entry. Reduce heat sources in the room, such as computers or electronics. Deactivate the SLEEP function. If using solar power, ensure sufficient grid power is available.

  If an error code appears on your Deye Air Conditioner, the unit may stop or continue running safely. Wait about 10 minutes to see if the problem resolves itself. If the error persists, disconnect both solar and grid power, wait 2 minutes, and reconnect. Then, turn the unit back on. If this doesn't work, turn off the unit.

Why does my Deye Air Conditioner change to FAN mode automatically?
- T
  Theodore WilliamsAug 27, 2025
  Your Deye Air Conditioner might switch to FAN mode to prevent frost formation. In this case, wait for the temperature to increase, and it will return to the previous mode. Alternatively, the set temperature may have been reached, causing the compressor to turn off. The unit will resume normal operation when the temperature fluctuates again.

Why are my Deye DGA2-ACDCBLW-12K indoor and outdoor units making noises?
- J
  Jacob SellersSep 6, 2025
  A low hissing sound during operation is normal, caused by refrigerant gas flowing through both units. A low hissing sound when the system starts, stops, or is defrosting is also normal, due to the refrigerant gas stopping or changing direction. Squeaking sounds can occur due to the expansion and contraction of plastic and metal parts caused by temperature changes during operation.
