OEM replacement control panel assembly (optical/eyebrow board) for Norcold N8DC and N10DC series DC compressor refrigerators with serial number SE079WDW00190 and above. Supersedes 640089 and 640338. Previously known as Norcold part number 641592.
The Norcold 51023 is the OEM replacement control panel assembly for Norcold N8DC and N10DC series DC compressor refrigerators — the front-mounted optical/eyebrow board that provides the user interface for temperature display, mode selection, and operating controls. Previously known as Norcold part number 641592, this is the same direct-fit assembly under an updated part number.
The 641592/51023 supersedes both earlier control panel boards for these models — the 640089 and 640338. There is a critical serial number break: the 51023/641592 is for N8DC and N10DC units with serial number SE079WDW00190 and above only. Earlier-production units (SN below SE079WDW00190) use the 640338. Locate the serial number from the label inside the refrigerator before ordering.
