Norcold Power Boards

Norcold Power Boards & Circuit Boards — Find the Right Board by Model

Need a Norcold power board? We stock every Norcold power board still in production, plus aftermarket replacement boards for older models no longer made by Norcold — including boards for the N7, N8, N10, N611, N811, N1095, 1200, 1210, 2118, and DC series. Use the model guide below to find the exact board for your refrigerator, or contact us with your model and serial number and we'll match it for you.

Where is the power board on a Norcold refrigerator?

The power board (also called the circuit board) is mounted behind the refrigerator, accessed from outside the RV. To reach it:

Remove the exterior access panel on your RV where the refrigerator vents.
Remove the board cover to expose the power board.
Before disconnecting anything, cut both AC power and battery (DC) power to the refrigerator.
Take a photo of the existing wiring layout before removing any wires — this makes reinstalling the new board fast and mistake-free.

Frequently Asked Questions

Do you carry every Norcold power board?
Yes. We stock every Norcold power board currently in production, plus aftermarket boards from Dinosaur Electronics for older Norcold models Norcold no longer supports.

How do I know which power board fits my Norcold refrigerator?
Match your refrigerator's model number and serial number to the table above. Many older models changed board design partway through production, so the serial number — not just the model — determines the correct board.

Is it safe to replace a Norcold power board myself?
Most RV owners can replace a power board themselves with basic tools. Always disconnect both AC and battery power before starting, and photograph the wiring before removing anything.

What if my part number isn't listed here?
Email us at info@rvfridgeguys.com or call 1-800-712-8822 with your model and serial number and we'll identify the correct board for you.
