Genuine Norcold replacement rear power control board for N4104, N4141, and N4150 series gas absorption RV refrigerators. Previously part number 692249.
The Norcold 51058 (previously part number 692249) is the genuine OEM rear power control board for Norcold N4104, N4141, and N4150 series gas absorption RV refrigerators — the circuit board mounted at the rear of the refrigerator that manages power distribution and controls operation across the refrigerator's AC (shore power), DC (12V), and LP (propane) modes. When the power board fails, the refrigerator may not operate in one or more modes, display fault codes, fail to ignite on LP, or not cool at all.
Norcold's N4104, N4141, and N4150 are four-door gas absorption refrigerators — they use propane or AC shore power to drive an absorption cooling cycle, not a compressor. The power control board manages which heat source is active based on the mode selected and available power. Using only genuine Norcold replacement parts is important: per Norcold's own service documentation, generic or aftermarket parts do not meet Norcold's specifications for safety, reliability, and performance, and their use voids the refrigerator's limited warranty.
• 1x Rear power control board Confirm your Norcold model (N4104, N4141, or N4150) from the label inside the fresh food door or on the back of the unit before ordering.
Common symptoms of power board failure on these Norcold models: • Refrigerator won't operate in any mode: Check 12V fuse and DC power supply first before replacing board • Works on LP but not AC (or vice versa): One heat source circuit on the board has failed • Check light illuminated with no other obvious cause: Board fault — refer to Norcold's troubleshooting documentation for fault code interpretation • No ignition on LP despite gas supply confirmed: Board may not be triggering ignition circuit Before replacing the board, verify input voltage at the board connections and check the AC heating element (part 638215) and gas valve (part 636873) independently — a board that appears failed may be responding correctly to a failed downstream component.
Per Norcold's official service documentation: "Generic parts do not meet Norcold specifications for safety, reliability, and performance. The use of unauthorized aftermarket or generic replacement parts voids the refrigerator's limited warranty coverage." This applies specifically to control boards, which must meet Norcold's safety and electrical specifications to function correctly with the refrigerator's LP and AC heating systems.
