Why does the red light of Panasonic air conditioner flash?

It may be that the weather is too hot, the radiator of the outdoor unit is dirty and blocked and the heat cannot be dissipated, or there is a problem with the fan. The radiator needs to be cleaned. It may also be that there is a lack of refrigerant and refrigerant needs to be added.

1. Check whether the weather is too hot or the outdoor unit radiator is dirty and blocked and the heat cannot be dissipated. This is why you have to unplug the power and wait a few minutes before turning it on. After the machine is shut down, the pressure returns to equilibrium and the machine cools down before it can be started. It is recommended to clean the outdoor unit radiator with clean water or spray some air conditioning cleaning agent.

2. Check whether the fan is the cause. If it can cool down normally when it is first turned on, it means that the air conditioner compressor and Freon are basically normal. Focus on checking whether the speed of the outdoor fan is normal. If the outdoor fan does not rotate or the speed slows down, it will affect the normal operation of the air conditioner. The current will increase, and the compressor will be overloaded and cause thermal protection. 3. Check whether there is a lack of refrigerant. Panasonic air conditioners are different from other brands of air conditioners. For domestic air conditioners, the internal unit tube temperature sensor does not participate in the work during cooling. This is because the internal unit evaporator temperature is not detected in front of the internal unit tube temperature window during cooling operation. Panasonic air conditioners generally detect the tube temperature when the compressor is working for about ten minutes. If there is too much refrigerant and the temperature cannot meet the requirements, the machine will shut down for protection. The air conditioner now shuts down for protection after running for half an hour. It should be caused by lack of refrigerant.
