Power failure

1. Check whether the power outlet is powered. If there is no current output from the socket, you need to contact the power supplier to solve the problem.

Set temperature problem

1. Check whether the air conditioner set temperature is too high. If the set temperature is higher than the indoor temperature, the air conditioner cannot be turned on. After lowering the set temperature, try turning it on again.

#2. Check whether the temperature sensor of the air conditioner is damaged. If damaged, professional maintenance personnel should be contacted for replacement.

Protection function activated

Outdoor unit problem

1. Check whether the outdoor unit is working properly. Failure of the outdoor unit will also cause the air conditioner to fail to start normally. It is necessary to contact professional maintenance personnel for maintenance.

Indoor temperature sensor problem

1. Check whether the air conditioner indoor temperature sensor is damaged. If the sensor is damaged, it should be replaced in time.
