Gree Air Energy Outside Machine Not Working? Why does the outdoor unit of Gree air conditioner run f

The reason why the Gree air conditioner does not work. First: low voltage or aging lines.

Second: The electric buzzer does not sound, please check the transformer. Third:

The red indicator light of the external unit does not light up. Fourth: The external unit has a power supply, the red indicator light is on, the external unit does not start, you can check the communication between the internal unit and the external unit.

The solution to Gree air conditioner not working. 1: Check whether the power supply of the external unit is electric or whether the voltage reaches the rated voltage. If it is not the cause of low voltage, please check whether the indoor and outdoor units are connected correctly, and whether the wires are aging.

The air conditioner does not work: Generally, the main control board is broken, the connection line is broken, the joint is loose, the contact is poor, the compressor is broken, etc. If it is not possible to shut down and restart, it is recommended to contact the after-sales service, or ask a professional maintenance personnel to check and repair. FYI.

Two possibilities. One is the motherboard failure, which may be that the motherboard interface is broken or not plugged in tightly, or the motherboard is broken.

There is also a situation where the fan fails, and the fan failure is generally directly replaced by the fan.

The contactor of the air conditioner is broken and cannot be connected to the indoor and outdoor units, resulting in the power supply being unable to be transmitted to the outdoor units;

2. The voltage is too low, resulting in the outdoor unit and indoor unit cannot be started, especially during the peak period of electricity consumption, the voltage is easy to be insufficient.

3. If there is a problem with the circuit board of the air conditioner, it will directly cause the air conditioner to fail to operate.

It is recommended to use a multimeter to measure the motor winding resistance and the insulation resistance to the ground to see if there is any abnormality, and at the same time measure the actual capacity of the motor capacitor.

Dear, I am glad to answer for you: 1. If it is the outdoor pressure leakage machine of the inverter air conditioner, it has been running non-stop; It's normal. The control logic of the inverter air conditioner is that when the room temperature reaches the set temperature, the compressor will reduce the frequency and power to operate, and the cooling capacity of the compressor at this time is equal to the heat load demand in the room, and the compressor runs at a very low frequency to maintain the room within the positive and negative degrees of the set temperature to achieve the effect of constant temperature control.

Unlike fixed-frequency air conditioners, which adopt the on-off operation mode of compressors, the room temperature fluctuates greatly and is less comfortable. Therefore, it is normal for the external unit of the first draft inverter air conditioner to be running all the time. 2. The water discharged by the outside is the condensate generated by the internal machine, and the water indicates that the refrigeration of the machine is normal.

The cooling capacity of your machine is 3500 watts, and it can only be used in a room of less than 18 square meters, and it is used in a room of more than 26 square meters, perhaps because the set temperature is difficult to reach, so the compressor will not shut down. If you are sure that the set temperature is reached, then the compressor will definitely shut down, and what you see is the cooling fan of the external unit, which is not synchronized with the compressor. 3. If the room temperature probe is broken, it will not display the actual temperature of the room, it should be that the computer board is broken.

The relay won't be released, it feels, one thing I can confirm, your refrigeration system is very normal! It's a matter of control circuitry. 4. The compressor of the air conditioner has been working without stopping.

Because the outdoor unit is just a compressor, and the others are small parts, the so-called outdoor unit is actually a compressor. After the initial operation of the compressor; Due to the running-in of the parts and the cleaning of the lubricating oil, a large number of fine metal powder enters the lubricating oil, so the machine should replace all the lubricating oil after 24 hours of work. After 200 hours of operation, change the oil again.

After two replacements, change the oil as required by regular maintenance.

The Gree air conditioner cannot be turned on if it does not start.

Lu Zai、、、 1. Remote control:

1. The screen appears garbled or frozen. Press the reset button to disarm, or the battery is low.

2. The temperature is not displayed. In air supply or automatic mode, the remote control does not display the temperature.

3. If the receiving head is broken or cannot work normally due to moisture, check the transmission of the remote control signal. Use a digital camera (mobile phone is also available) to point at the transmitter port of the remote control, and press any button on the remote control to see if there is an infrared signal emitted.

4. The remote control mode is incorrect, or the temperature setting does not meet the boot conditions. When cooling, the set temperature should be less than the indoor temperature, and when heating, the set temperature should be greater than the indoor temperature.

5. The battery of the remote control is low, which will cause the remote control distance to be short or unable to be remotely controlled. It is recommended to take out the remote control companion battery when the Gree air conditioner is not in use, and reinstall or replace it when in use.

2. Power supply voltage:

1. The power supply is not connected or out of power, the power conductor is rotten, the macro socket is not in good contact, or the power conductor wire diameter is thin or aging.

2. The power supply voltage is low. Fixed frequency Gree air conditioner starting voltage: 187V, voltage fluctuation range:

198-242V, the starting voltage of the inverter Gree air conditioner: 156V, the voltage fluctuation range: 176-264V, it is recommended to install a voltage regulator at home.

3. Protection function:

1. Delay protection. In order to protect the life of the press, the control circuit of the Gree air conditioner computer board is designed with a protection circuit, and the press is started after a delay of 3 minutes.

2. Prevent heating and cold air. When the heating of Gree air conditioner is working, when the temperature of the indoor unit coil is lower than a certain value, the internal unit does not run, and generally after 3-5 minutes of preheating, the internal unit starts to work.

3. The computer program of Gree air conditioner is chaotic, which makes the machine unable to work immediately.

Summary. 2. If it is heating mode, there are two situations: (1) The machine has entered the defrost operation.

If you observe, if this situation only lasts for about 5 to 15 minutes, and the machine can start heating operation again, that is, the internal fan starts working again, it is normal defrosting operation. If the internal fan is not running all the time, there is a problem. It may be caused by a lack of fluorine, or it may be that the heating effect of the machine itself is not good, so that the temperature of the inner coil cannot go up, so the internal fan cannot be opened, because the heating operation of the general air conditioner must meet the temperature of the inner coil higher than 30 to 36 ° before the internal fan is allowed to operate.

Because if you run it before this temperature, it will blow cold air. (2) There is a lack of fluorine, but if there is a lack of fluorine, it will generally stop for about 10 minutes and show the fault**.

Hello, dear, very happy for your question, what is the reason why the household Gree air can be plugged in and the external machine works, help you find out, possible reasons: 1. If Hongchongguo is in refrigeration mode, then your indoor unit has a problem, it may be a problem with the wind wheel lifting machine, or it may be a question of the control board.

2. If it is the heating mode, there are two situations in the poor shed: (1) the machine has entered the defrosting operation. If you observe, if this situation only lasts for about 5 to 15 minutes, and the machine can start heating operation again, that is, the internal fan starts working again, it is normal defrosting operation.

If the internal fan is not running all the time, there is a problem. It may be caused by a lack of fluorine, or it may be that the heating effect of the machine itself is not good, so that the temperature of the inner coil cannot go up, so the internal fan cannot be opened, because the heating operation of the general air conditioner must meet the inner coil temperature higher than 30 to 36 ° before the internal fan is allowed to operate. Because if you run it before this temperature, it will blow cold air.

(2) There is a lack of fluorine, but if there is a lack of fluorine, it will generally stop for about 10 minutes and show the fault**.
