K. Removal and Replacement of Door Gasket

Remove the old gasket by pulling it directly out of the vinyl gasket retainer. Thoroughly clean the gasket area with mild soap and water prior to installing the new gasket. The new gasket should be installed at the corners first, then working toward the center at the top, bottom, and sides. The arrow-shaped portion of the gasket should be firmly seated in the retainer groove for proper assembly. This can be checked by lifting the edge of the gasket and observing the engagement.

CAUTION

In order to get a proper gasket fit, it is important not to stretch gasket material during assembly.
