What is the reason that Gree air conditioner shows that E6 is not cooled? Hangzhou air-condition maintenance

It may be caused by poor thermistor of indoor heat exchanger. Solution: 1 Open the cabinet of the indoor cabinet and check whether the thermistor connectors of the internal and external heat exchangers are firm and reliable. 2. Unplug the thermistor and measure its resistance at room temperature, and then measure its resistance after heating. If the resistance does not change, it is determined that the thermistor has been damaged. The fault code of E6 displayed by air conditioner represents different meanings on different models, 1, and the fault code of E6 in frequency-fixing cabinet represents the abnormality of electrostatic precipitator. It is necessary to check whether the electrostatic precipitator itself or the connecting wire is damaged and whether there is too much dust on the surface. 2. In other commercial cabinets, the fault code of E6 indicates that the communication signal between the indoor unit and the outdoor unit is abnormal, and it is impossible to supply power to the outdoor unit or the outdoor unit control motherboard. To check whether the connecting wires of the indoor unit and outdoor unit are mismatched or have poor contact, pay attention to check whether the phase wire and the zero wire of the air conditioning power cord are connected reversely. Precautions: When the air conditioner fails, it must be operated in strict accordance with scientific procedures, and it is forbidden to act blindly and disassemble it at will in the case of unknown situation and failure. Such consequences will often expand the existing faults, increase operating costs, shorten the normal service life of equipment, and lead to premature scrapping of equipment.
