In summer, the weather is very hot, the use of air conditioning is more and more frequent, more and more failures. Many people use Gree air conditioner. What's wrong with Gree air conditioner? Come with Xiaobian to see what happens when Gree air conditioner can't turn on!
Gree air conditioner can't turn on
Remote control reason
1. When the screen of the air conditioner remote control appears disorderly code or freeze frame. Press the reset key to release, or the battery is low.
2. The air conditioning remote control does not display temperature. In the air supply or automatic mode, the temperature will not be displayed on the remote control.
3. It may be that the remote control of the air conditioner cannot transmit signals normally. It is necessary to check whether the remote control signals are transmitted. Use a digital camera or mobile camera to aim at the transmitter of the remote control, press any key of the remote control, and then check whether there is red light in the camera or mobile camera. If there is any indication that the air conditioner can send signals normally, if not, the remote control is broken.
4. The remote control mode is incorrect or the set temperature does not meet the starting conditions. During refrigeration, the set temperature shall be lower than the room temperature, and during heating, the set temperature shall be higher than the room temperature.
5. The battery of the remote control is dead or low, which will lead to the short control distance of the air conditioner remote control or failure to remote control. It is recommended to remove the remote control battery when the air conditioner is not used, and then reinstall the battery back to the air conditioner.
Reasons for air conditioning power supply
1. The air conditioning power supply is not well connected or the socket is not powered, the power socket is in poor contact, or the power lead is aging.
2. The power supply voltage is low or unstable, the starting voltage of the constant frequency air conditioner is 187v, the voltage fluctuation range is 198-242v, the starting voltage of the variable frequency air conditioner is 156v, and the voltage fluctuation range is 176-264v. If the voltage is lower than these, the air conditioner will not work. It is recommended to use the voltage stabilizer to stabilize the voltage before connecting the air conditioner.
What's the matter with Gree air conditioner unable to turn on? Many users use the air conditioner remote control to control the air conditioner to turn on, but the air conditioner does not turn on. What's the reason? Let's find out.
Self protection function of air conditioner
1. Self protection
In order to protect the life of the air conditioning compressor, there is a protection circuit in the control circuit of the air conditioning computer board. The compressor will not start until three minutes after it is started.
2. Heating to prevent cold air
When the air conditioning heating works, there is a temperature sensor on the indoor unit coil. Only when the coil temperature reaches a certain temperature, the air will be blown. When the air conditioner is just turned on, the internal unit does not operate. Generally, the air will be blown after 3-5 minutes of preheating.
3. Air conditioning program confusion
When the computer program of air conditioning is in disorder, that is, when the air conditioning control system fails, the air conditioning can not carry out the specified work.
4. Function lock protection
Now many air conditioners have child lock function, which is designed to prevent children from randomly pressing when they won't use it. No operation can be carried out in child lock mode, and only operation can be carried out by unlocking the child lock.
