Gree air conditioner E9's simplest treatment method

The appearance of E9 in Gree air conditioner means that it is in the operation mode of "cold air protection". After the automatic defrosting of the external unit, the air conditioner switches to the heating mode again. When the temperature sensing sensor of the internal unit senses that the temperature on the heat exchanger is higher than the temperature of the room temperature sensing sensor, the internal unit will automatically switch back to the heating mode, turn on the fan of the internal unit, and the state of E9 will be released naturally.

E9 is basically not a fault. It is a control display in which the indoor heating is stopped when the automatic defrosting is carried out due to the frosting of the external unit during the operation of the heating mode. Therefore, the control stops the operation of the indoor fan to prevent the cold air from blowing out.

In the heating mode, the outdoor fan will frost due to low temperature, which will affect the heating capacity. At this time, the air compressor will automatically enter the defrosting mode, and the indoor coil temperature will decrease. In order to prevent cold air from blowing out, the indoor fan will also stop running, and the code E9 will be displayed, indicating that the air conditioner is currently in the defrosting stage, and the internal fan will stop supplying air. In order to prevent cold air, wait until the defrosting is completed, The E9 display will disappear. (GeLiKongDiaoe9ZuiJianChanDeChuLiFangFa)
