Common faults and treatment methods of Gree air conditioning
1. What's wrong with Gree air conditioner e6?
1. Gree air conditioner shows e6, which may be a communication failure. When the black connecting wire between the indoor unit and the outdoor unit is loose, there may be communication failure.
2. Gree air conditioner displays e6. There may be something dirty in the indoor unit, such as dust or dirt. Too much dust will affect the size of the air outlet, leading to the decline of the refrigeration function of Gree air conditioning.
3. Gree air conditioner displays e6, which may be that the fan motor of the outdoor unit of the air conditioner is out of power. When the outdoor unit of air conditioner is damaged, there may be no power supply, and e6 will be displayed.
4. Gree air conditioner shows e6, which may be that the outdoor compressor is overloaded, that is, if the compressor is used for too long or improperly, it will be overloaded and the compressor will be stopped for protection.
Second, the simple solution of Gree air conditioner e6*
1. First, you can replace the signal connection line between the indoor unit and the outdoor unit. This is why e6 may appear. If e6 is still displayed after replacement, it is necessary to measure the power supply voltage of the signal port of the external unit board. If there is a voltage of about 5V, the voltage is ok.
2. If the voltage is ok, there may be something wrong with the inverter motherboard or module. You can measure the signal port of the external machine board. If the power supply voltage is about 0V- 1V, the indoor unit control circuit board is abnormal and needs to be replaced.
3. If the frequency conversion module of the outdoor unit of the air conditioner is hot or the power supply is abnormal, it means that there is something wrong with this module, and it can be restored to normal after replacing the module.
Gree air conditioner has been used for a long time, and the failure to clean the filter screen in time leads to the blockage of internal air circulation, which will affect the heating effect of the air conditioner to a certain extent. Excessive dirt on evaporator and condenser will also reduce the heat transfer effect, resulting in a decrease in heating capacity and an increase in power consumption; The heating temperature is set too low. Air-conditioned room door, hole is not blocked, or often open the door, resulting in indoor heat loss. , it will inadvertently cause air conditioning heating weakness.

1. Insufficient refrigerant: a simple self-check can be conducted to determine whether there is fluorine leakage.
2. Four-way valve cross air: the heat pump air conditioner switches the cooling and heating states through the four-way valve. Some refrigerants that should participate in heat exchange directly flow back to the air return pipe from the compressor outlet pipe at the four-way valve, which leads to the decrease of refrigerants participating in heat exchange and the decrease of heat exchange efficiency, thus resulting in insufficient heating capacity.
3. Leakage of one-way valve (also known as check valve): the pressure difference between high and low pressure in refrigeration system decreases, the temperature of outdoor heat exchanger increases, and the heat obtained from the outside decreases, resulting in insufficient heating capacity. When testing the system pressure, it will be found that the low pressure side pressure rises and the pressure difference between high and low pressure drops.
Maintenance tips:
1. All costs of this order need to be confirmed with the merchant (engineer) in the actual service process, and the costs will be charged according to the actual situation;
2. The door-to-door fee of this order (out of warranty period) does not include maintenance material fee, management fee, labor fee, etc.
