Replacement Refrigerator Control Board — DA4100536A / DA4100288A This circuit PCB is a direct replacement control board for refrigerators and freezers that use part numbers DA4100536A or DA4100288A. It restores electronic control of cooling, defrost and user interface functions when the original motherboard fails, helping avoid a full appliance replacement. Key benefits Restores normal refrigerator operation by replacing a failed control board. Costeffective option compared with replacing the whole refrigerator. Direct fit for appliances that use DA4100536A or DA4100288A — plugandplay compatibility when installed correctly. Helps eliminate common electronic faults such as no cooling, intermittent compressor operation, or nonresponsive display panels. Main features and attributes Functionality: Replaces the appliance's main electronics that manage compressor, fans, defrost cycle, temperature sensors and display/indicator logic (as implemented by the original control board design for these part numbers). Compatibility: Specifically for refrigerators and freezers that require control board DA4100536A or DA4100288A. Verify the part number on your original board or in your appliance manual before ordering. Construction: Printed circuit board (PCB) populated with the required electronic components and connectors for direct replacement of the listed control board models. Performance: Restores factory control behavior and timing sequences when installed in a compatible appliance. Performance depends on correct installation and the condition of other refrigerator components (compressor, sensors, wiring). Size and fit: Form factor and connector layout match the original DA4100536A / DA4100288A boards for straightforward replacement in compatible models. Confirm physical match and connector alignment before installation. Installation and usage notes Turn off and unplug the refrigerator before attempting any . Follow safety precautions and appliancespecific service instructions. Confirm your existing board's part number (DA4100536A or DA4100288A) to ensure compatibility. If you are not experienced with appliance electronics, consider professional installation to ensure correct wiring and system diagnostics. After installation, verify sensor connections and run standard diagnostic checks to confirm restored operation. Typical use cases a failed control board that causes the refrigerator to stop cooling or to run continuously. Fix a refrigerator with an unresponsive display, incorrect temperature readings, or repeated electronic error codes associated with the main control board. Maintain a service inventory for appliance technicians who support models that require DA4100536A or DA4100288A boards. Compatibility reminder This board is intended only for refrigerators and freezers designed to use DA4100536A or DA4100288A control boards. Always confirm the exact part number on the existing board or in the appliance documentation before .
