NORCOLD INC Refrigerator Power Circuit Board 628661 - Direct-Fit Post-2006 RV Replacement, Restores Electrical Control

The Norcold 628661 Refrigerator Power Circuit Board is a direct-fit replacement board that routes power to your RV refrigerator’s components, restoring electrical control and operational reliability.

If your Norcold RV refrigerator is not getting the correct voltage or has intermittent electrical behavior, the 628661 power circuit board is designed to replace the original control board in many post-2006 Norcold models. Built from durable components and sized for straightforward installation, this board serves as the main power distribution and control interface that ensures compressors, fans, and valves receive the proper power signals.

How does this board restore my refrigerator’s electrical function?

Replacing a worn or damaged power board with the 628661 re-establishes the internal pathways that deliver voltage to sensors, fans, compressors, and control relays. The board handles switching and distribution so each subsystem gets the correct current and timing signals.

• Direct-fit form factor for many Norcold models made after 2006
• Replaces faulty wiring or burned contacts that cause intermittent operation
• Delivers regulated power to critical refrigerator components
• Simplifies troubleshooting by eliminating board-related failures

Which Norcold refrigerators are compatible with the 628661 circuit board?
