What if Haier's air conditioner stops when it can't reach the temperature?

Troubleshooting and operation methods:

The normal power supply voltage of Haier air conditioner is within the range of 220v10%. When it is detected that the power supply voltage of Haier air conditioner is lower than 198V, if the voltage of inverter Haier air conditioner is too low, after the inverter Haier air conditioner is turned on, the power supply voltage will gradually decrease with the operating power of the compressor, and the final voltage will be lower than that of inverter Haier air conditioner, and an alarm of "undervoltage protection" will be issued.

Frequency conversion Haier air conditioner or ordinary fixed frequency Haier air conditioner just started to operate normally, but after a period of time or longer, Haier air conditioner could not reach the temperature and the outdoor unit stopped. The reasons may be as follows:

Turn-off protection caused by low power supply voltage;

Observe whether there are walls or objects around the installation position of outdoor unit that affect heat dissipation protection;

It is normal that Haier air conditioning is affected by outdoor high temperature, and the cooling capacity and effect are obviously reduced.

Prevent the outdoor unit from overheating due to too long direct sunlight;

Haier air conditioning refrigerant shortage leads to compressor protection;

Whether the connecting pipeline of Haier air conditioner is bent or the refrigeration system is faulty.
