Automatic hardware detection method, device and equipment for air conditioner computer board and air conditioner

The invention provides an air conditioner computer board hardware automatic detection method, device and equipment and an air conditioner, and relates to the technical field of air conditioners. The method comprises the steps that under the condition that an air conditioner computer board is powered on, the air conditioner computer board starts a hardware self-checking mode; determining a detection sequence of to-be-detected hardware based on the hardware self-detection mode; and detecting the hardware to be detected according to the detection sequence to obtain a detection result, and judging whether a hardware circuit input port of the air conditioner computer board is normal or not, and judging whether a hardware circuit output port is normal or not. According to the embodiment of the invention, whether each port of the hardware circuit of the air conditioner computer board has a quality problem or not can be conveniently detected, and the air conditioner computer board enters a hardware self-checking mode
