common faults of gree air conditioner and their treatment methods
1. What is the fault of gree air conditioner e6? 1. When Gree air conditioner displays e6, it may be a communication fault. When the black connecting wire between indoor unit and outdoor unit is loose, it may be a communication fault. 2. Gree air conditioner displays e6, which may be that there are dirty things inside the indoor unit, such as dust or dirt. Too much dust will affect the size of the air outlet, resulting in the decline of the refrigeration function of Gree air conditioner. 3. Gree air conditioner displays e6, which may be that the fan motor of the outdoor unit of the air conditioner is not powered on. When the outdoor unit of the air conditioner is damaged, it may have no power supply, and e6 will be displayed. 4. Gree air conditioner displays e6, which may be that the outdoor compressor is overloaded, that is, the compressor will be overloaded if it is used for too long or improperly, and the compressor will be shut down for protection. Second, Gree air-conditioning displays e6 * Simple solution 1. First, you can replace the signal connection line between the indoor unit and the outdoor unit, which is the reason why e6 can appear. If e6 is still displayed after replacement, you need to measure the power supply voltage of the signal port of the external unit board. If there is a voltage of about 5V, it means that there is no problem with the voltage. 2. If there is no problem with the voltage, it may be that there is a problem with the frequency conversion motherboard or module. You can measure the power supply voltage of the signal port of the external board. If the power supply voltage is about V-1V, it means that 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 the module, and it can be restored to normal after replacing the module. After long-term use of Gree air conditioner, the filter screen was not cleaned in time and the internal air circulation caused blockage, which would affect the heating effect of air conditioner to some extent. Too thick 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 setting is too low. Air-conditioned room door, wall hole is not blocked, or doors and windows are opened frequently, resulting in indoor heat loss, etc. will inadvertently cause air-conditioning heating is not strong.

Insufficient refrigerant: whether fluoride leaks can be identified through simple self-inspection. 2. Four-way valve cross gas: the heat pump air conditioner switches the cooling and heating states through the four-way valve. Some refrigerants participating in heat exchange should directly return from the compressor outlet pipe to the return pipe at the four-way valve, which leads to the decrease of refrigerants participating in heat exchange and the decrease of heat exchange efficiency, resulting in insufficient heating capacity. 3. Leakage of one-way valve (also known as check valve): the pressure drop of refrigeration system rises and falls, the temperature of outdoor heat exchanger rises, and the heat from outside decreases, resulting in insufficient heating capacity. After testing the operating pressure of the system, it will be found that the pressure on the low pressure side increases and the pressure difference between high and low pressure decreases.
