The refrigerator control board is the core controller in the refrigerator circuit system, which plays the role of adjusting and controlling the temperature, humidity and other parameters of the refrigerator. It usually consists of multiple functional modules such as chips, memories, and interface circuits. Working principle: The working principle of the refrigerator control panel is to control the compressor, air cooler and defrosting heater through the on and off of the control circuit, and then complete the control of the entire refrigeration and fresh-keeping system. When the temperature or humidity inside and outside the refrigerator exceeds the normal range, the control board will send an alarm signal according to the program logic. The refrigerator control board has built-in multiple protection mechanisms, such as over-current protection, over-voltage protection, over-temperature protection, etc., to ensure the reliability and safety of the entire circuit system. At the same time, the refrigerator control panel can support more functions through program upgrades, improving intelligence and convenience.
