Gree air conditioning low voltage protection is generally due to insufficient supply voltage or power line fault caused. To solve the problem of low voltage protection, you can try the following methods:
1. Check the power cable: First, check whether the power cable of the air conditioner is normal. Ensure that the power plug and socket are in good contact to avoid voltage instability caused by poor contact. If the power cable is damaged or aged, replace the power cable.
2. Check the power supply voltage: The rated voltage of the air conditioner is 220V. If the power supply voltage is insufficient, the low voltage protection will be triggered. You can use a voltmeter to measure the power supply voltage. If the voltage is lower than the standard voltage, contact the power department for processing.
3. Replace the starting capacitor: The starting capacitor in the air conditioner is a key component to control the start of the air conditioner. If it is damaged or aging, it will lead to insufficient starting current, causing low voltage protection. The starting capacitor can be replaced to solve the problem of low voltage protection.
4. Adjust the air conditioning Settings: If the above methods can not solve the problem, you can try to adjust the air conditioning Settings. In air conditioning Settings, there is usually a low voltage protection switch that can be turned off to disable the low voltage protection function. However, this method is not recommended for long-term use, because long-term use will increase the risk of failure of the air conditioner.
It is important to note that if you do not have the relevant skills and experience, do not disassemble and repair the air conditioner yourself. It is recommended that you contact professional air conditioning maintenance personnel for maintenance and treatment.
Gree air conditioning low voltage protection is set to protect the air conditioning circuit from the impact of voltage fluctuations. If there is low voltage protection, you can first check whether the power line is normal, whether there is loose or poor contact. If the power line is normal, try adjusting the voltage stabilizer or replacing the power outlet. If the problem still exists, it is recommended to contact a professional air conditioning maintenance personnel for inspection and repair. At the same time, usually when using air conditioning should also pay attention to keep the power supply stable, to avoid excessive voltage fluctuations.
Gree air conditioning low voltage protection solution is as follows
1. The outdoor unit condenser (that is, the fin of the external unit) is too dirty, and it is solved after cleaning.

2 inside the voltage is too low (less than 170V) in the morning or night, other people's homes do not use electricity, try to try, if the power is low install a regulator after the solution.

3 Whether it has been repaired? It may be that there is too much fluorine or there is air in the system. Discharge the excess fluorine or evacuate the air again to solve the problem. If you have not fixed the system, this problem can not be considered.

4 The system has gambling (dirty gambling oil gambling) find a professional maintenance man, clean the entire system with nitrogen, and then re-evacuate the solution after fluoride.

5 Start capacitor problems or compressor itself problems, find professional maintenance personnel to solve.

6 Computer board inductance part of the problem, find professional maintenance personnel to solve.

7 The natural ambient temperature is more than 38 degrees Celsius, it is also possible to cause compressor overflow, the most easy at noon, the night is better. Natural ambient temperature drop point naturally good.
The first step is to determine if the ambient temperature is too low.
The second step is to determine whether it is a control fault or a system fault, you can first short-connect the LPP plug on the main control board and the zero line N on the main board, if the indoor unit is running normally, you can determine that the indoor unit motherboard or display board is no problem, and the fault occurs in the indoor and outdoor unit connection cables, connectors or outdoor unit low-voltage switches.
Step 3 Determine the room. Connect the cable and plug of the external machine, adjust the multimeter on the ohm stop, connect one watch pen to the LPP protection line pulled out on the main board, and connect the other watch pen
First check whether the low pressure value is too low, and restore the pressure to normal by adding fluoride. The lack of fluorine compressor can not be cooled by enough cold refrigerant, and it will be hot, resulting in thermal internal protection of the compressor and shutdown.

The second is whether it is dirty or blocked, such as capillary, expansion valve is dirty or ice blocked, replace the capillary or clean the expansion valve. The blockage causes low pressure at the suction end, or even negative pressure. If refrigerant is constantly charged, the suction pressure will not come up
