Refrigerator Motherboard Main Control Board，Compatible For Samsung， DA41-00287F DA41-00286A

Core Control and Scheduling: It receives data from all sensors, calculates internally, and issues instructions to coordinate all components such as compressors and fans to work together to ensure the orderly operation of the system. Precise frequency conversion control: drive the frequency conversion compressor and fan motor, and adjust their operating speed steplessly according to the temperature and set value in the box, so as to achieve smooth switching from high-frequency cooling to low-frequency insulation Excellent silent experience: The variable frequency drive eliminates the need for the compressor to start at full power repeatedly, so as to achieve smooth and low-noise operation, greatly reduce the starting noise of traditional refrigerators, and create a more peaceful home environment for users Stable and durable, high reliability: Industrial-grade components and rigorous circuit design with perfect overvoltage and overcurrent protection ensure that the motherboard works stably for a long time in complex environments and has a longer lifespan. Energy-saving mode operation: Under low ambient temperature or user settings, it automatically enters the low-power operation mode to reduce the operating frequency of the compressor and the speed of the fan, so as to achieve the purpose of energy saving.
