Norcold RV Refrigerator Power Circuit Board | 628661 | 12V DC

Restore reliable operation to your Norcold RV refrigerator with the Norcold 628661 Power Circuit Board. This genuine Norcold OEM replacement power board is the critical component that manages power distribution and operational logic for your RV refrigerator — controlling heating elements, cooling cycles, and the electrical systems that keep your fridge running. When the power board fails, you'll see symptoms ranging from a completely unresponsive fridge to erratic operation to no cooling at all.

Cross-Reference Part Numbers

This same Norcold power circuit board is referenced under several alternate part numbers depending on the supplier or catalog:

• 628661 (primary)
• 03-2420
• 121468
• 391559
• NO628661

If your existing board or supplier documentation shows any of these numbers, this 628661 is the matching replacement.

What This Board Does

The power circuit board is one of the critical brains of your Norcold refrigerator. It manages:

• Power distribution across the refrigerator's electrical components
• Heating element control for the cooling cycle (Norcolds use absorption refrigeration, which uses heat to drive cooling)
• AC and DC power switching on dual-power models
• Temperature regulation logic
• Safety circuits that protect the unit from electrical faults

Common Failure Symptoms

Common reasons to replace the power circuit board include:

• Refrigerator completely unresponsive — no display, no operation
• Erratic operation — intermittent function or unexpected shutdowns
• No cooling despite the unit appearing to power on
• Heating element not activating
• Error codes on the control panel
• Switching between AC and LP gas modes fails
• Power supply issues isolated to the board after testing

Before assuming the power board is the cause, rule out simpler issues — wiring connections, AC and DC power supply, fuses, and thermistor function — since these can mimic board failure symptoms. Our RV Refrigerator Not Cooling troubleshooting guide walks through the typical diagnostic path.

Genuine Norcold OEM Replacement

As a Norcold factory replacement part, the 628661 is built to original specifications for a precise drop-in fit in compatible refrigerator installations.

⚠️ Professional Installation Recommended

Refrigerator power board replacement involves working with both AC and DC electrical systems, plus LP gas system interfaces on dual-fuel models. Installation should be performed by a qualified RV service technician. Improperly installed control boards can result in safety risks, refrigerator damage, or fire hazards. Always verify proper operation after installation.
