G. Removal and Replacement of Door Gasket
Remove 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

center at the top, bottom and sides. The arrow-shaped portion of the gasket should be
rmly 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 t, it is important not to stretch gasket material
during assembly.
