OEM replacement top control panel board for Norcold N15DC and N20DC series DC compressor refrigerators. The front-facing board that manages user controls, temperature display, and refrigerator operating modes. Fits all serial numbers. Previously known as Norcold part number 641043.
The Norcold 50977 is the OEM replacement control panel board for Norcold N15DC and N20DC series DC compressor refrigerators — the top-mounted board at the front of the refrigerator that handles user interface functions including temperature display, mode selection, and operational status indicators. Previously known as Norcold part number 641043, this is the same direct-fit board under an updated part number.
When the control panel board fails, symptoms typically include a blank or incorrect display, unresponsive controls, incorrect temperature readings shown, or the refrigerator not responding to mode changes. Fits all serial numbers on both N15DC and N20DC models — no serial number break for this board. These are the DC compressor models — confirm "DC" appears in your refrigerator's model number before ordering.
• 1x Norcold 50977 control panel board Other N15DC / N20DC parts: • 50888 / 640149 — Thermistor and cover • 50907 / 640178 — Compressor Power Module (CPM) • 641033 — Ice maker (N15DC/N20DC ice maker models)
• Display blank or showing incorrect/garbled readings • Temperature buttons or mode controls unresponsive • Refrigerator displays fault codes and will not reset • Display works but refrigerator does not respond to inputs Before replacing the control panel board, verify the thermistor (640149/50888) is functional — a faulty thermistor can cause erratic display behavior and is a less expensive first replacement to try.
The 50977/641043 is the control board for N15DC and N20DC models only. The smaller N8DC and N10DC use different control boards. Confirm your exact model designation before ordering — locate the model number on the interior label of the refrigerator.
