How to repair Gree inverter air conditioner h5, what is going on with the display of Gree inverter a

Gree inverter air conditioner H5 indicates two kinds of faults:

1.Module overtemperature protection.

2.module undervoltage; Overcurrent protection. (Gree inverter air conditioner uses two different modules, and H5 has two meanings).

Gree inverter air conditioner H5 code fault causes and quick solutions:

1.The temperature sensor in the module is damaged. (This situation can be fixed.) The air conditioner failure phenomenon is that the compressor stops after working for a few seconds. Repair method: Modify the sensor circuit and replace it with a fixed resistor.

2.The operating temperature of the air conditioner is too high, resulting in an increase in current. The overcurrent protection of the module may cause the module to overheat, and the indoor unit will display the H5 code.

This situation can also be fixed. Fault phenomenon: The air conditioner is working normally at first, and it will not be normal after a while.

Maintenance method: clean the internal and external units, and add refrigerant according to the amount.

3.Compressor problems lead to h5 yards, starting the fan is running normally and the compressor is not working. After a few seconds, the VTH shows an H5 fault**. (In order to distinguish between the compressor problem and the external plate problem, you only need to dial the compressor line and try the machine again to draw conclusions).

4.The drive voltage of the module is lower than 15V or higher than 15V. When the drive voltage of the module is lower than 15V or higher than 15V, the indoor unit displays an H5 fault**. Fault phenomenon: When a similar problem occurs, most air conditioners can run for a period of time.

5.The module current detects a fault. When the module current detection is wrong, the indoor unit will also display H5**. The fault symptom is that the compressor stops after working for a few seconds.

Gree air conditioner displays H5, which means module protection, that is to say, the air conditioner may be the power module with poor heat dissipation.

Solution: 1. Check whether the operating current of the compressor, the speed of the outdoor fan, and the heat dissipation of the outdoor unit are good;

2. Whether the heat dissipation paste between the module and the heat sink is evenly applied, etc.;

3. You can try it with the elimination method, disconnect the compressor and turn on to see if the output AC voltage of U, V and W is balanced, and see if it will be displayed after running for a while;

4. If it is displayed, it should be the motherboard, and if it is not displayed, it should be the poor heat dissipation of the outdoor unit.

Tips: Don't operate it easily, just find a manufacturer of Gree's after-sales service for maintenance.

Gree inverter air conditioner h5** fault causes and quick solutions:

1. The temperature sensor contained in the module is damaged. (This situation can be repaired, and the failure of the air conditioner is that the compressor stops after working for a few seconds).

Maintenance method: Replace the sensor circuit with a fixed resistor by modifying the sensor circuit.

2. The operating environment temperature of the air conditioner is too high, resulting in an increase in current.

The module overcurrent protection may cause the module temperature to be too high, and the indoor unit will display H5**. (This situation can also be repaired, fault phenomenon: the air conditioner just started to work normally, and after a while it will not be normal).

Maintenance method: clean the internal and external units, re-evacuate the refrigerant and add it according to the amount.

3. The compressor problem causes H5**, the start-up fan runs normally, and the compressor does not work.

After a few seconds, the indoor unit shows an H5 fault**. (In order to distinguish between the compressor problem and the outer plate, it is only necessary to remove the compressor line and test the machine again to draw conclusions).

4. The driving voltage of the module is less than 15V or higher than 15V.

When the module drive voltage is lower than 15V or higher than 15V, the indoor unit will display H5 fault**, fault phenomenon: most air conditioners can run for some time if they have similar problems.

5. The module current detection is faulty.

When the module current detection is wrong, the indoor unit will also display H5**, and the fault phenomenon is that the compressor will stop after working for a few seconds.

Gree inverter air conditioner H5 indicates two kinds of faults:

1. Module overheating protection.

2. Module undervoltage; Overcurrent protection. (Gree inverter air conditioner uses two different modules, and H5 also has two meanings).

H5 is module protection; Generally, if you start and run it a few times, the fault can be eliminated; (Power off, power off and back on); However, if H5 is displayed as soon as it is turned on, it means that the electrical box of the external unit is faulty; There are several points that cause module protection: the external unit does not dissipate heat well; There is sun exposure on the outside machine; When refrigerating, there is too much refrigerant; If the power supply voltage is too low, it will cause module protection;

H5 is module protection; The specific cause of the fault needs to be detected and dealt with by Gree service personnel. Please contact Gree National Customer Service**4008-365-315 for feedback on your needs and suggestions, or click here.

Make an appointment for the service.

It doesn't matter if you have zero foundation or a poor foundation, you can repair the motherboard!

The machine is faulty and needs to be solved by workers.

Hello dear, I'm very happy to answer for you, I'm sorting out the answer, typing slowly, wait 4-5 minutes.

Dear, I am very honored to tell you that the Gree air conditioner shows H5 to indicate that the power module has poor heat dissipation. You can check whether the compressor operating current, the speed of the outdoor fan, the heat dissipation of the outdoor unit is good, and whether the heat dissipation paste between the module and the heat sink is evenly applied. You can try it with the elimination method, disconnect the compressor and turn on to see if the output AC voltage of U, V, and W is balanced, and see if it will be displayed after running for a while.

Hope mine is helpful to you.

Questions. Thank you.

I hope mine can help you, please give a thumbs up, thank you.

H5 Failure**: Reasons why "Module Protection" may appear to be H5;

Gree inverter air conditioner displays **H5 when the module heat dissipation is not good and the temperature is high;

Module protection: Overcurrent protection and overheat protection, check whether the AC and DC voltage is too low, and whether the compressor is overloaded.

H5 is module protection, and the specific cause of the fault needs to be detected and dealt with by Gree service personnel.

The temperature sensor included in the module is damaged. The phenomenon is that the press stops after working for a few seconds. Solution: Change the sensor circuit and replace it with a fixed resistor.

The ambient temperature of the air conditioner is too high, causing the current to increase. The overcurrent protection of the module may cause the module temperature to be too high, and the H5 fault will be reported. Generally easier to maintain.

Gree air conditioner H5 fault causes and solutions: Gree air conditioner displays H5, which means module protection, that is to say, the air conditioner may be the power module with poor heat dissipation. Check the operating current of the compressor, the speed of the outdoor fan, whether the heat dissipation of the outdoor unit is good, and the heat dissipation paste between the module and the heat sink.
