What's the matter with Gree air conditioner showing H5? What to do if the air conditioner shows H5

In daily life, the air conditioner may have some faults after long-term use. At this time, the fault code will appear on the air conditioner display screen, which part of the problem will be displayed. So what's the matter with the H5 of Gree air display?

Causes and solutions of H 5 fault in Gree air conditioner

Gree air conditioner displays H5, indicating module protection, that is to say, air conditioner may have poor heat dissipation of power module. Check the running current of the compressor, the rotating speed of the outdoor fan, whether 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 use the elimination method to test, turn off the compressor to see if the output AC voltage of u, V and W is balanced, and see if it will display after running for a while. If it is displayed, it should be the main board. If it is not displayed, it should be the poor heat dissipation of the outdoor unit. Tip: don't operate it easily, just find the manufacturer of Gree's after-sales service.

If the indicator light of the internal unit goes out for 3D and flashes for 3 times during the operation of the air conditioner, and then prompts H5 code on the display, it means that the system enters the low-pressure protection program. Generally, it is caused by the lack of fluorine, or it may be caused by the blockage of expansion valve, solenoid valve failure and other problems.

If the machine prompts H5 error, the following problems need to be analyzed. The first step is to determine whether the ambient temperature is too low, the second step is to determine whether the control fault or the system fault, the third step is to determine whether the connecting wires and plugs of indoor and outdoor units are loose, and the fourth step is to determine whether the fluorine leakage or the refrigerant is blocked through the pressure gauge.

What to do if the air conditioner shows H5

The simplest solution is to inform the after-sales service department to carry out on-site maintenance, especially for the air conditioner in the warranty period. The charge for on-site maintenance is very low. If the machine is in fault, the replacement of internal parts or maintenance is free, and the warranty period of new parts is recalculated from the time of replacement.

If you want to check the problem at home first, you need to test whether the pressure of the refrigerant is enough. If it is enough, check the circuit of the pressure switch and the pressure switch. Measure whether the low-pressure switch is on. If it is on, pull out the line and check whether there is 220V power. If there is no problem in the above inspection steps, you must contact the after-sales department.
