Why is my Gree GWC18KG-K3DNA5A indoor unit not blowing air?
- M
  Mark OrrSep 9, 2025
  In HEAT mode, the unit will stop delivering air to prevent cool air when the indoor heat exchanger temperature is very low. Also, in HEAT mode, if the outdoor temperature is low or humidity is high, frost may form on the outdoor heat exchanger, causing the unit to automatically defrost. In dehumidifying mode, the indoor fan may stop to prevent condensed water from vaporizing again and to restrain temperature rising.

  The noise from the indoor unit of your Gree Air Conditioner could be the sound of the fan or compressor relay switching on or off. It can also occur when defrosting starts or stops.

  If your Gree Air Conditioner's wireless remote control isn't working, first, try pulling out the power plug and reinserting it. Check if you are within the receiving range and if there are any obstructions. Ensure the batteries in the remote are charged or replace them. Finally, consider whether the remote control may be damaged.

Why is my Gree Air Conditioner leaking water outside?
- M
  Megan BeckerAug 27, 2025
  If your Gree Air Conditioner is leaking water outside, it could be due to condensation on the pipe and pipe connections when running in COOL mode. It could also be from the thawing of ice during Auto Defrosting mode, or water dripping off the heat exchanger when running in HEAT mode.

Why is my Gree GWC18KG-K3DNA5A indoor unit not delivering air?

  Shawn LunaSep 16, 2025
  In HEAT mode, the Gree Air Conditioner may stop delivering air to prevent cool air when the indoor heat exchanger temperature is very low. Also in HEAT mode, when the outdoor temperature is low or humidity is high, frost can form on the outdoor heat exchanger, causing the unit to automatically defrost, during which the indoor unit stops blowing air for 3-12 minutes. In dehumidifying mode, the indoor fan may stop to prevent condensed water from vaporizing again and to restrain temperature rising.

Why is there moisture on my Gree GWC18KG-K3DNA5A Air Conditioner air outlet vent?
- O
  oatkinsonSep 18, 2025
  If your Gree Air Conditioner runs under high humidity for a long time, moisture may condense on the air outlet grill and drip off.

Why does my Gree Air Conditioner emit mist in COOL mode?
- S
  Sara TaylorSep 7, 2025
  If your Gree Air Conditioner emits mist from the air outlet vent in COOL mode, it's likely due to high indoor temperature and humidity. This mist should disappear once the indoor temperature and humidity decrease after the unit runs for a while.

Why is my Gree GWC18KG-K3DNA5A Air Conditioner cooling/heating inefficiently?
- A
  April SmithSep 4, 2025
  Several factors can affect the cooling or heating efficiency of your Gree Air Conditioner. Check if the temperature setting is appropriate, ensure that the air inlet and outlet vents are not obstructed, and verify that the filter is clean. Also, make sure windows and doors are closed properly, the fan speed isn't set too low, and there aren't any heat sources in the room.
