Replaced the door gasket in this Frigidaire-made Kenmore on Sunday. Soaked for about 30 minutes in hot water to get the wrinkles out, removed about 1/4 of the screws at a time during replacement, put a hair dryer to it to get it nice and soft again, applied a thin film of Vaseline, closed the door and taped shut for 2 days to set the seal. Customer called today and said it isn't set on the top corner opposite the hinges. Does this need to set awhile more to get the seal set, is the door sprung, or do I need to adjust the door or gasket. It seals great except for that one area.
