What happened to h5 when Gree air conditioner was cooling?

This fault code indicates that the air conditioner is defrosting, which means that the air conditioner is no longer in a cooling state. This is a normal phenomenon and will disappear after defrosting. Generally, it is a problem that only air conditioners with alternating hot and cold will exist, so don't worry too much. It is hot in summer, and every household is equipped with air conditioning. Now air conditioning can be regarded as a necessary appliance for every household. If there is a problem with the air conditioner in use, you can find the instruction manual with the fault code and find the corresponding solution. If Gree air conditioner has fault code h5, it means that the air conditioner voltage is relatively low. Once the voltage is lower than 220 volts, Gree air conditioner will have h5 code. First of all, you need to use professional air conditioning equipment to measure the voltage of the air conditioner. If it is caused by a voltage problem, wait until the voltage is stable before using the air conditioner or reinstalling the voltage regulator. Fault code h5 appears because the outdoor unit of the air conditioner has poor heat dissipation effect, or because the air conditioner has been cleaned and maintained irregularly for a long time and accumulated a lot of dust, so the heat dissipation effect cannot be achieved. In this case, the condenser can be cleaned and the air conditioner needs regular maintenance. However, if there is something wrong with the electric box of the air conditioner, you need to contact professional maintenance personnel, because the electric box is controlled by a computer board of Gree air conditioner, and it is normal for this kind of fault to occur. You just need to find a professional maintenance person.
