What s going on when the Gree air conditioner doesn t work?

Gree air conditioner. The external machine does not work due to the following reasons:

Low voltage or aging lines. It is recommended to 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, whether the wires are aging, and whether the motherboard of the indoor unit is wired correctly, otherwise replace the motherboard of the internal unit.

If the external unit has a voltage of 220V, check whether the red indicator light on the motherboard of the external unit is on, if the indicator light is not on, check whether the external unit connection line is loose and the power module.

Whether there is a direct voltage of about 300V between P+ and N-, if not, check the reactor.

Rectifier bridge and wiring. If there is, but the indicator light of the motherboard of the external unit does not light up, first check whether the signal cables (10 in total) from the power module to the motherboard are loose or have poor contact.

If the outdoor unit has a power supply, the red indicator light is on, and the external unit does not start, you can check that it is the communication between the internal unit and the external unit, and any kind of light flashing is normal, otherwise there is a problem with the communication; Check whether the connecting wire of the internal and external machine is a special flat wire, and replace it in time if not, so as to avoid similar situations again.

If the communication is normal, please check whether the indoor and outdoor temperature sensor packs are open or short circuited or the resistance value is abnormal, and whether the overload protector port is connected. If the above two methods cannot solve the problem, replace the outdoor controller.

If the air conditioner is turned on for about 10 minutes and cannot be started, please check whether the indoor pipe temperature sensor package is open; If the machine is started again after starting, and the external fan is not started, check whether the indoor and outdoor temperature sensing heads are short-circuited.

The Gree air conditioner does not work, as you described, if the refrigeration is normal, it means that the compressor of the air conditioner is normal. His appearance of H4 should be defrosted, and it can only be started after the defrost is completed.

What's going on with the Gree air conditioner not working, Gree air conditioner not working, isn't it you, what is the matter with the Gree air conditioner not working? Gree air conditioner is not working, is it you to check if it is a problem with the circuit? It's not a problem with the circuit, what is the matter with the Gree air conditioner not working?

Gree air conditioner is not working, is it you to check if it is a problem with the circuit? If it weren't for the circuit problem, then your external machine might be out of order, go to the maintenance personnel.

1.Low voltage or aging lines.

2.The electric buzzer does not sound, please check the transformer.

3.The red indicator light of the external unit does not light up.

4.The external unit has a power supply, the red indicator light is on, the external unit does not start, and it can be checked that it is the communication between the internal unit and the external unit.

5.The air conditioner is turned on for about 10 minutes and stops and cannot be started.

6.The environment in which the air conditioner is located is relatively hot, and the air conditioner cannot be started.

Under normal circumstances, the outdoor unit of the air conditioner will not run all the time, when the indoor temperature reaches the temperature you set, the outdoor unit and the indoor unit will stop at the same time, and then the air conditioner will run again when the indoor temperature rises. Any machine needs to rest, and working non-stop for a long time is to reduce life or damage. If the air conditioner doesn't stop working, it's out of order or the room is not well insulated.

It may be because the remote control mode of the air conditioner is incorrect, just check whether the setting of the remote control is the refrigeration mode, adjust the mode to the state of showing refrigeration or snowflakes, or it may be because of the power supply problem that causes the air conditioner to not work, you need to pay attention to observe whether the outdoor unit has a working sound, if the compressor is not started, you should check whether the power supply is normal.

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;

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.

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

Clause. 1. Low voltage or aging line. If the air conditioner cannot be turned on, it is necessary to 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 the room

I said that if the Gree air conditioner does not work, it means that there are some quality problems, and you should find some professional personnel to check it.

When the room temperature is close to the set temperature, the air conditioner fan will stop rotating, and the compressor can work normally, then the air conditioner will not fail. Therefore, if the Gree air conditioner does not work, you should check whether the compressor of the air conditioner can work normally.

Take it apart to see if there's something short circuited inside or something that's stuck.

A: The problem description is still not clear. The simple fan motor of the outdoor unit and the simultaneous operation of the fan motor & compressor are two completely different situations, but the difference is not too big in terms of appearance.

The rough judgment is that there is a fault in the air conditioning system, such as a serious leak in the refrigerant or an abnormality in the main control component of the unit, resulting in the compression of the outdoor unit.

Gree air conditioner. The external unit does not work because of the incorrect remote control mode, power supply problems, and voltage reasons

OneThe remote control mode is incorrect, first check whether the remote control is set to refrigeration mode, and then use the air conditioner remote control.

Adjust the mode to "cooling" or "snowflake" and set the temperature to 26 degrees Celsius or below.

IIIf the outdoor unit fan is running, it means that the control circuit is normal, and then you should observe whether the compressor is started.

IIIFor the reason of voltage, 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 and seepage, please check whether the indoor and outdoor units are connected correctly, and whether the wiring of the main board of the indoor unit is correct.

Attention should be paid to the installation of the air conditioner outdoor unit:

1. The installation location of the hall ridge air conditioner should be in an open place, avoiding things such as shelters and leaves, and not affecting the fan outlet and fan heat.

2. The air conditioner will emit vibration and noise, and it is best to stay away from the location of the bedroom, so as not to affect the rest.

3. It is best not to put the air conditioner directly on the ground in rainy days.

It is easy to accumulate water, which leads to rust and corrosion of parts. The lack of maintenance of the external unit will increase the load of the fan after a long time, or the external unit will often vibrate and cause the screws to loosen.

4: Please check whether the indoor tube temperature sensor bag is open; If the machine is started again after starting, and the external fan is not started, check whether the indoor and outdoor temperature sensing heads are short-circuited.

Hope it helps.

All of the above reasons cause the external machine to not work.

The internal machine works, and the external machine does not respond, which can be checked from the following aspects:

1. Check the power switch and possible circuit problems

1. Please check whether the power switch is turned on.

2. Please check whether the power plug is plugged into place.

3. Please reinstall the battery correctly or replace it with a new one.

4. Control circuit board failure.

5. The temperature sensor is overloaded and the information is wrong.

6. The starting capacitor or compressor starting coil is burned.

2. The phenomenon that the compressor protection device may trip: the compressor overload protection will trip to represent that the high-pressure pressure of the system is too high or the overheating current is too large.

Causes and elimination of high pressure and overheating:

1. If there is too much refrigerant, the refrigerant dose should be reduced.

2. Poor heat dissipation, the environment in which the air conditioner is located is relatively hot, and the air conditioner cannot be started. In addition, check the condenser pipe for dirt and dirt, and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

Due to the fact that there are many reasons for professional knowledge, it is recommended to find a professional maintenance personnel to check it.

I'm sorry Douyan, we don't have time to guess the imperial law for this problem, I can't solve this problem and I don't dare to give you easy methods and suggestions, please consult the relevant personnel to give you the correct answer, I wish you a happy life.

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.

The power switch may not be turned on: Please turn on the power switch.

There may be poor contact between the power plug and the socket: check that the power plug is plugged into place.

It is possible that the remote control battery is dead or cannot be remotely controlled when it is installed backwards: please reinstall the battery correctly or replace it with a new battery.

Household air conditioners come with 3 meters of copper pipes from the factory, which are part of the product itself. Some consumers who are more than 3 meters have to pay separately, but since it is sold to consumers by the manufacturer, it is also within the scope of the three guarantees, but the three guarantees have a deadline, and you have not said how long you have been buying, so it is not good to help you analyze.

The national three guarantees stipulate: 7 days of return, 15 days of replacement, one month of repair (repair refers to free maintenance). This is the bottom line, that is, each manufacturer can extend the three-guarantee period on this basis, but it must not be less than the above standards.

The thermostat knob is not adjusted properly, and the reason is that it is not adjusted properly;

The refrigerant leakage in the thermostat's temperature sensing bag, and the thermostat fails to open and does not close, which may be due to the destruction of some parts of the thermostat, or the refrigerant leakage due to manufacturing quality problems;

The contact of the overload protector is in the disconnected position, and the reason is that the refrigeration system is overloaded during operation, which makes the overload protector jump open;

The operating capacitor of the compressor is damaged, which may be due to improper maintenance or moisture intrusion;

The compressor and dagger burned out.
