Why is my Gree GWH12MB-D3DNA3D indoor unit not delivering air?
- M
  Mary LongSep 3, 2025
  If your Gree Air Conditioner's indoor unit isn't delivering air, here are some potential reasons: * In HEAT mode, the unit may stop delivering air to prevent cool air when the indoor heat exchanger temperature is very low. * In HEAT mode, the unit will automatically defrost when the outdoor temperature is low or humidity is high, causing the indoor unit to stop blowing air for 3-12 minutes. During defrosting, water may flow out or vapor may be produced. * In dehumidifying mode, the indoor fan may stop to prevent condensed water from vaporizing again and to restrain temperature rising.
