Method for judging the failure of an air conditioning pressure sensor: Power it separately and check if the zero-point output is accurate. If it is accurate, apply pressure and observe if there is any change in the output. If there is a change, it indicates that the sensor itself is functioning properly. A sensor is a detection device that can sense the measured information and convert the sensed information into an electrical signal or other required form of information output according to certain rules. The pressure sensor is installed on the pipeline of the outdoor unit of the air conditioner to detect pressure, and transmits the pressure detection results to the computer board, thereby controlling other components of the air conditioner.
