A "waffle" door has a textured interior liner with a molded grid pattern. A "smooth" door has a flat, smooth liner. They also use different door bins, so match the style of your current door when ordering. The Lower Door 623955/638835 is the smooth-interior version, and it has been discontinued by Norcold. The N611/N621/N641 is discontinued too, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide.
