What is the reason why the internal unit of Gree air conditioner is working normally and the externa

First of all, make sure that your air conditioner is faulty and not working. In your question, the specific symptoms are not clearly stated, so the cause of the failure is not certain, probably the following situations: 1. Compressor damage (there are several situations), 2. Compressor capacitor damage, 3. Fan motor damage, 4. Fan capacitance damage, 5. Some other system protection, etc.

If the capacitor is damaged, the situation is easy to do, you can replace one, if the compressor is damaged, then the maintenance is more troublesome, the warranty does not need banknotes, and the maintenance cost is close to four digits if it is out of warranty! Good luck.

The internal unit of the air conditioner is normal, and the external unit of the air conditioner does not start, which is caused by 4 situations:

1. The power supply is off. Check the power supply circuit. The indoor unit and the outdoor unit are connected by the AC contactor, and the power supply is also transmitted through this channel, so when the AC contactor is damaged, it means that the outdoor unit and the compressor cannot receive the power supply, and the outdoor unit cannot work normally.

2. Freon leaked. The amount of freon is limited, too much or too little will cause the air conditioner to work abnormally, at this time the self-protection system of the air conditioner, there will be a high-voltage protection automatic switch on and off for self-protection.

3. The condenser is polluted. The outdoor condenser also has its own self-protection system, which is activated when it is not cleaned regularly.

4. Computer board failure. The operation of the outdoor unit is controlled by the computer board, so when the outdoor unit is not running, it may also be the fault of the computer board.

5. The compressor and outdoor unit are burned out. It will also cause the external machine to not function.

Check whether the wires connected to the external machine have ** or the link is loose. It is also possible that the external capacitor is burned, which needs to be checked. It's better to ask a professional to check it out.

The so-called frequency conversion is to save energy, I don't know what you mean by the normal operation of the internal machine, is the indoor cooling (heating) operation is normal or the internal machine only runs but does not reach the target temperature of the operation.

If it is the former, then you don't need to worry, because as long as the inverter air conditioner reaches the target working condition you set, it will automatically adjust the working state, of course, including the shutdown of the external unit; If the latter is the case, then it is a problem with your machine, find after-sales service.

Remove the power supply cover of the external unit, measure whether there is a 220V voltage input with a universal meter, and check whether the terminal is connected properly. The starting capacitor has not burned out.

1. The remote control mode is incorrect.

Check whether the remote control is set to refrigeration mode. Using the remote control of the air conditioner, adjust the mode to display "cooling" or "snowflake", and set the temperature to 26 degrees Celsius or below.

2. Power supply problems.

Pay attention to whether the outdoor unit has working sound (including outdoor unit, fan and compressor). If the outdoor unit fan is running, the control circuit is basically normal. At this time, you should observe whether the compressor starts or not, and if the compressor does not start, you should check whether the power supply is normal.

3. The reason for the voltage.

If the air conditioner can't be turned on, it is necessary to check whether the external power supply 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.

4. No maintenance for a long time.

The analysis of the reasons why the outdoor unit of the air conditioner does not rotate for a long time may be loose in terms of structure, which may be the loosening of the locking part of the screw and the wind wheel; The flat position of the motor and the mating part of the wind wheel are not in the proper position; Due to the problems of injection molding process assurance, the plastic parts have a squeaky sound, the air guide strip and the connecting rod mechanism belong to plastic parts, and the transmission performance of the structure of the air guide strip, stepper motor and connecting rod mechanism is affected, which will also cause the indoor unit to not run.

5. The ambient temperature is too high, resulting in system protection.

When the ambient temperature is too high, the sun is direct and there is no shading object, the outdoor unit has poor ventilation and a mesh cover or the wall is blocked in front of the outdoor unit, the air conditioning heat cannot be blown out, and the temperature is too high, the compressor will automatically start the protection and stop working to avoid damage to the compressor.

6. AC contactor failure.

Power on the AC contactor, measure the outlet end of the AC contactor with a multimeter to see if there is a voltage of 380V, if not, it means that the AC contactor is damaged internally, and a new AC contactor needs to be replaced.

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 conditionerThe 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.

The internal unit of the air conditioner shows that there is electricity, but the external unit and the internal branch infiltration machine are not working, first check whether the temperature sensor of the air conditioner is different from the usual, and whether the compressor of the air conditioner is faulty.

The internal unit of the air conditioner shows that there is electricity, but the external unit and the internal unit do not work as usual, because its internal program has appeared a pure and accurate performance, so you need to adjust their intelligence in the wrong performance, so you need to adjust their intelligence, in some functions and working programs.

This one is obviously out of order. This can only find a maintenance master. Just check. to know the reason.

Summary. Hello dear! The reasons why the internal unit of the air conditioner has electricity and the external unit does not have power are as follows:

1. Too much refrigerant. Reduce the refrigeration dose appropriately. 2. Poor heat dissipation.

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 exhaust temperature of the compressor will be overheated, which will cause the superheating load protection switch to trip. Hello dear! The above is my answer to this question, if you think I am very satisfied, please follow me for a one-on-one consultation in the future, and then please do it a little manually, give me a thumbs up!

Welcome to consult again!

Hello dear! The reasons why there is no power in the inside unit of the air conditioner and no power in the outside unit are as follows: 1. Too much refrigerant.

Hello dear! The above is my answer to this question, if you feel that I am very satisfied with the noise, please pay attention to me for a one-on-one consultation in the future, and then please do it a little manually, give me a like! Welcome to consult again!

I used it last year, and I just started it this year.

It is recommended to carefully check whether the relay powered by the outdoor unit on the main control board of the indoor unit can be used to work as usual, whether the power cord from the indoor unit to the indoor potato external unit is loose or broken, and whether there are obvious abnormalities in the appearance of the main control panel. If there is an obvious abnormality, the abnormality should be ruled out first. At the same time, check whether the remote control signal command to the indoor unit is effective, and whether there is any abnormal fault in the signal connection line between the remote control signal receiver and the main control board.

Summary. Dear, if the air conditioner has power inside and the outside unit has no power, there are the following reasons and solutions: 1

The power supply is abnormal or disconnected. Check the power supply circuit. The indoor unit and the outdoor unit are connected by the AC contactor, and the power supply is also transmitted through this channel, so when the AC contactor is damaged, it means that the outdoor unit and the compressor cannot receive the power supply, and the outdoor unit will not be able to work normally!

2.Freon leaked. The amount of freon is limited, too much or too little will cause the air conditioner to not work properly, at this time the self-protection system of the air conditioner will appear high-voltage protection automatic switch on and off for self-protection!

3.Contaminated condenser. The outdoor condenser also has its own self-protection system, and its self-protection system will be activated when it is not cleaned regularly!

Freon leaked. There is a certain limit to the amount of freon in Xiaochen, too much or too little will cause the air conditioner to work abnormally, at this time, the self-protection system of the air conditioner will appear high-voltage protection automatic switch on and off for self-protection! 3.

Contaminated condenser. The outdoor condenser also has its own self-protection system, and its self-protection system will be activated when it is not cleaned regularly!

Kiss, according to the teacher's experience, if the above aspects are all right, then it is the fault of the following aspects: Block 1Computer board malfunction.

The operation of the outdoor unit is simply known to be controlled by the computer board, so when the outdoor unit is not running, there will also be a fault of the computer board! In this case, the teacher does not recommend that you disassemble the Weibo without permission, and you need to find a professional to repair it to avoid secondary damage and safety accidents! <

Dear, in general, the compressor, outdoor unit burned out. It will also cause the dongqiao outsider to not work. The air conditioner is powered on and does not work, and the display screen does not display. The air conditioner is normally wide and clear, and the air conditioner does not start!
