Function overview: The refrigerator motherboard is the core control component of the refrigerator, which is responsible for coordinating and controlling the various functions of the refrigerator Working principle: The motherboard collects the temperature, humidity and other information inside the refrigerator through sensors, analyzes and processes it, and sends instructions to the compressor, fan and other components to adjust the cooling capacity and air circulation, and maintain the set temperature and environment in the refrigerator. Maintenance precautions: The power supply of the refrigerator must be cut off first during maintenance to avoid the risk of electric shock. When disassembling the motherboard, pay attention to recording the location and interface of each cable to prevent errors during installation. Compatibility: Different brands and models of refrigerators have different specifications, interfaces and control logic of their motherboards, and generally cannot be used universally. When replacing the motherboard, choose a motherboard that matches the make and model of the refrigerator to ensure its compatibility and proper functioning. Maintenance: Keep the refrigerator motherboard clean to avoid dust and moisture accumulation, and wipe the surface of the motherboard with a clean soft cloth regularly., Weight: 2.20462262 Pounds, Manufacturer: AHYLN
