The timing light of Panasonic inverter air conditioner keeps flashing.

The flashing light is generally a fault, and then a flashing alarm prompt is given. The reason is: 1, the refrigerant is insufficient. If there is too much refrigerant and the temperature cannot meet the requirements, the machine will stop for protection. 2, air conditioning high voltage fault and protection downtime. It may be that the weather is too hot and the radiator of the outdoor unit is dirty, so turn it off to protect the fuselage. It may be that the tube of the temperature sensor is damaged. The general tips of panasonic air conditioning signal lights are as follows: the timing light flashes 15 times; When the fault is an instantaneous breakpoint, the single chip microcomputer is reset. The timing light flashes 14 times: the single-chip microcomputer failed to read EEPROM data. Timing light flashes 12 times: the fault is that there is a problem with outdoor heat exchange during refrigeration, and the sensor temperature exceeds 70℃ for protection. Timer flashes 1 1 time: instantaneous power-off protection. Timing light flashes 10 times: the fault is caused by overvoltage and undervoltage of power supply. The timing light flashes 7 times: the fault is the outdoor heat exchange sensor fault. The timing light flashes 6 times: the fault is the outdoor ambient temperature sensor fault. The timing light flashes 5 times: the fault is overcurrent protection. The timing light flashes for 4 times: the fault is that the temperature of the compressor temperature sensor exceeds 120℃ during heating. The timing light flashes twice: the fault is that the induced current of the current sensor is too small. Timing light flashes 1 time: the fault is caused by overheating, overcurrent and short circuit of the power module.
