Product review (4 stars): Great replacement
This gasket replaced a 15 year old gasket on an Amana freezer. The old gasket was leaking quite a bit and would not keep the door closed very well. The new gasket was a great replacement. It helps if you can remove the door and lay it on a flat surface to unscrew the old gasket. At this point either heat the new gasket with a hair dryer or in the clothes dryer to soften it so it will fit around the door liner. You then screw in the new gasket.
As another reviewer stated, once you hang the door back on, the seal will look gappy and will not seat correctly against the freezer cabinet. To solve this, take some petroleum jelly and apply some to the gasket (this will help keep the seal). Then take a hair dryer to soften the gasket and run a flat head screwdriver along the dripline of the gasket to help seal it to the cabinet. Then keep the door closed for one to two days and the seal should be fine.
