How to fix a Tosot Air Conditioner when no air is emitted from the indoor unit?
- R
  ryantiffanyAug 16, 2025
  If no air is emitted from the indoor unit of your Tosot Air Conditioner, make sure that there are no obstacles blocking the airflow. Also, once the ambient indoor temperature reaches the set temperature, the indoor unit will stop blowing out air. After starting the heat mode the indoor unit will delay 1-5 minutes before blowing air.

  If you can’t adjust the set temperature on your Tosot Air Conditioner, it might be because the unit is running in auto mode, where temperature adjustments are disabled. Also, check if your desired temperature exceeds the set temperature range of 61°F(16°C) - 86°F(30°C).

  If your Tosot Air Conditioner isn't operating, there could be several reasons: * A power failure might be the cause. If so, wait for the power to be restored. * Ensure the unit is properly plugged in; reinsert the plug if necessary. * The unit may be undergoing a 3-Minute Compressor Protection cycle to extend its lifespan.

Why is my Tosot GWH09QCXB-D3DND4B/O making abnormal noises?
- C
  Chris AdamsAug 31, 2025
  If your Tosot Air Conditioner is making abnormal noises, it could be due to the following reasons: * A low hissing sound when the system starts, has just stopped running, or is defrosting is normal. This is caused by the refrigerant gas stopping or changing direction. * A cracking sound, also normal, results from the expansion and contraction of plastic and metal parts due to temperature changes during operation.

Why is my Tosot GWH09QCXB-D3DND4B/O Air Conditioner emitting white mist from the indoor unit?
- B
  brittney55Sep 8, 2025
  The white mist emitted from your Tosot Air Conditioner could be due to high indoor temperature or humidity levels. In humid regions, a large temperature difference between the room’s air and the conditioned air can cause white mist. After a while, indoor temperature and humidity will decrease and the mist will disappear.
