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.
Gree air conditioning after-sales process:
1. Users need to go to the special Gree air-conditioning after-sales service outlets for repair, and then contact the maintenance personnel. Note that if they are within the warranty period, they also need to provide warranty cards and useful purchase vouchers.
2. After the repairman comes to the door, he will check the defect of the product and then determine the cause of the defect. If the warranty period is right or wrong, then he needs to supply the charging standard to the user according to the regulations, negotiate the cost with the user, and then carry out the corresponding maintenance after the user agrees.
3. If there is a certain dispute between maintenance personnel and users during the maintenance process, maintenance personnel also need to restrain their emotions and respond to the company so that the company can handle it harmoniously.
4. After the maintenance is completed, the maintenance personnel need to repair and test the product with the user to see if it can be used normally, and also need to issue a formal receipt certificate after charging.
5. If parts need to be replaced for charging maintenance, special service outlets should use Gree Electric parts for replacement. Used parts should be left to users, and old parts should not be asked from users, and old parts that have been repaired with compensation should not be returned to the sales company.
6. For the loss of useful purchase vouchers, the date of product purchase can be calculated on the first day of the following month according to the factory date of the nameplate on the product body. For split air conditioners, the later delivery date in the internal machine or external machine should be considered. Perhaps the service network will check the actual purchase date with the sales company according to the barcode of the machine that the user reported for repair.
