What to do if the air conditioner protection light is flashing and not cooling

In the entire home repair industry, what can quickly arouse the attention of users is the previous TV repair, and the current air conditioning repair is also one.

　　 If you don’t believe me, as soon as the four words air-conditioning repair are placed in the search box, the problem of flushing will come out. More specifically, air-conditioning repair does contain too many problems.

　　Refrigeration is the standard core function of an air conditioner. Once a problem occurs, it will be fatal. Take the question of how to do if the air conditioner protection light flashes and does not cool.

　　 The fatal failure of air-conditioning not cooling has ruined the weekend and rest time of many people. In order to ensure that every family with air-conditioning can be cool for the summer, the reasons and solutions for the air-conditioning protection lights flashing and not cooling have been found out.

　　The possible cause is the tripping of the compressor protection device. The compressor overload protection tripping means that the high pressure of the system is too high or the overheating current is too large.

　　 Reasons for high pressure and overheating and troubleshooting:

　　 1. Too much refrigerant. Appropriately reduce the amount of refrigerant.

　　2. Poor heat dissipation. Check whether there is dirt on the condenser tube and clean the condenser.

　　 3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process the system.

　　4, the evaporator or filter is dusty and scaled. The airflow becomes smaller and the system pressure and temperature are not constant. Clean the evaporator or filter.

　　 5. Fluorine deficiency is also possible. In the absence of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

　　The circuit problem may be caused by the failure of the control circuit board; the temperature sensor is overloaded and the information is wrong; the power supply wiring is loose, the contact is poor, and the starting capacitor or the compressor starting coil is burned out.

　　 Of course, for home maintenance novices, these maintenance knowledge can only solve the puzzle, and the professional maintenance personnel can really solve the problem.

　　 Air conditioner failure is inevitable, but finding the cause of the problem can also relieve anxiety. Knowing the cause of the failure can prescribe the right medicine. It will be clearer and more convenient to communicate with maintenance personnel, and it will save a lot of trouble.
