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.
Before installing the refrigerator motherboard, you need to pay attention to the following items: 1. Ensure that the power supply is cut off: Before installing the refrigerator motherboard, it is necessary to cut off the power supply first to avoid electric shock or damage to the motherboard. 2. Inspection and cleaning: Before installing the motherboard, it is necessary to check whether the wires, cables and interfaces inside the refrigerator are intact, and at the same time clean the refrigerator to ensure a dust-free, mud-free, and water-free environment, which is conducive to the work of the motherboard. 3. Install according to the manual: Install the main board of the refrigerator correctly according to the operation guide in the product manual of the refrigerator. It is necessary to pay attention to the correct connection of the interface and the line to ensure that it is correct. During the installation process, you need to be careful not to forcibly mess up or pull the wires, otherwise the motherboard will be damaged. 4. Prevent static electricity: During the process of installing the mainboard, avoid static electricity, otherwise it will affect the work of the mainboard. Before installation, you can use anti-static materials to treat the physical condition and operating environment. fixation is found, spacers or other auxiliary fixation materials can be added.
