Why does Gree air conditioner automatically shut down after starting for a few seconds?

What protects the shutdown is the high-voltage fault of the air conditioner. The possible reasons are: the timing switch is on; The air conditioner is set to sleep mode; Air conditioning emergency switch reset failed; Poor contact between air conditioning cable plug and socket; Automatic protection function of air conditioner over-voltage; The weather is too hot, and the heat of the outdoor radiator cannot be dissipated; The compressor will be overloaded and thermally protected. Solution: 1 Check whether the timer switch option on the air conditioner remote control is turned on, and if it is, turn it off. 2. Check whether the remote control is in sleep mode. When the temperature reaches the specified temperature, it will automatically turn off. Just switch this mode to normal mode. 3. Look at the emergency switch of air conditioner. Unplug the power plug and dial it back by hand, which may be caused by its reset failure. 4. The plug of the air conditioning line is in poor contact with the socket. Try unplugging the air conditioner switch and plugging in another plug to see if it will turn off automatically. 5, caused by grid voltage. Because the air conditioner has the automatic protection function of over-voltage and under-voltage, when the grid voltage is unstable beyond the allowable range, the air conditioner will automatically stop. 6. It may be that the weather is too hot to dissipate the heat from the outdoor radiator. It is for this reason that it takes several minutes to turn on the machine after unplugging the power. 7, after downtime, pressure balance, the machine cooled down, you can start. It is recommended to clean the radiator of the outdoor unit, or spray water with clean water or air conditioning cleaner. 8. If it can cool normally when it is turned on, it means that the air conditioner compressor and Freon are basically normal, so it is very important to check whether the fan speed of the external machine is normal. 9. If the external fan does not turn or the rotation speed is slow, it will affect the normal operation of the air conditioner, increase the current, overload the compressor and protect against overheating.
