Norcold doesn't support non-Norcold cooling units, so they'll generally say an aftermarket unit isn't approved for their fridge, and installing one can affect Norcold warranty coverage. That said, the Nordic 6618 is built by Nordic specifically as a replacement for the 2118's original 637080 unit. Cooling units aren't returnable, so let us confirm the fit with your serial number. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
