The hotel air conditioner flashes red.

1, the red light of the air conditioner flashes, which may be because the indoor and outdoor air conditioning equipment can't communicate normally, and there may be interference from the external magnetic field, so the display panel of the air conditioner can be detected. 2. When the current is overloaded, it will also cause the red light of the air conditioner to flash. Sometimes the low voltage at home is too high, which will lead to the overload of air conditioning. In this case, the air conditioner will start the self-protection system, and the indicator light will keep flashing and flickering.
