What is the simplest way to deal with h5 of air conditioner?

The H5 fault code displayed by the air conditioner indicates "module protection". There are two reasons for this. One is that the module is overheated, the air conditioning module is not radiating well, and the code H5 is displayed when the temperature is high. The other is module undervoltage and overcurrent protection. Causes and solutions of H5 fault of air conditioner;

1. Check whether the AC /DC voltage is too low and the compressor is overloaded.

2. Check whether the compressor running current, outdoor fan speed and outdoor heat dissipation are in good condition.

3. Check whether the thermal paste between the module and the radiator is evenly applied.

4. The temperature sensor in the module is damaged, indicating that it works normally. The media will stop in a few seconds. The sensor circuit needs to be replaced by a fixed resistor.

5. Check whether the module is damaged due to short circuit and need to be replaced with a new module.

Maintenance after shutdown

It is a perennial law to turn on the air conditioner when the weather gets warmer and turn off the air conditioner when the weather gets cooler. Pay attention to the comprehensive and detailed inspection of outdoor units and indoor units before the air conditioner is turned off. Maintenance, maintenance and cleaning should be linked one by one, and cannot be separated. Leaked links should be fixed and strictly checked.

After the above steps are completed, cover the air conditioner to prevent dust pollution, dripping water and water from entering the air conditioner, keep it clean, and prepare to use it again next year, so as to achieve cleanliness, energy saving and prolong the service life of air conditioning equipment. Focus on protecting high-quality distributors and cabinets of well-known brands, and give full play to the energy-saving effect.
