Why does Haier air conditioner automatically shut down?

1. It may be because the weather is too hot and the indoor radiator is clogged, preventing the heat from dissipating. The air conditioner needs to be cooled before it can operate normally. 2. It may be a fan problem. 3. It may be caused by poor contact in the air conditioning circuit. 4. It may be due to accidentally turning on the timer on/off mode. 5. It may be that the starting capacitor of the outdoor unit cooling fan is damaged, the fan does not rotate, and the temperature is too high and the protection shuts down. Suggested treatment method: If it is caused by overheating, you can carefully clean the outdoor radiator. If it is too troublesome, you can also spray some water and air conditioner detergent on the air conditioner radiator. If it is a fan problem. When this happens, pay attention to the inspection of the external fan. When the current increases and the compressor is overloaded, it will automatically activate thermal protection. If it is caused by poor contact in the air-conditioning circuit, carefully check whether the air-conditioning circuit is operating normally and whether the air-conditioning power strip is plugged in properly. You can try to unplug the air-conditioning switch and plug it into another plug to see if it works. Automatic shutdown may also occur. If the air conditioner automatically shuts down, you can switch the mode to check, and then make reasonable solutions based on the actual situation.
