Ordered this Freezer Door Bottom From Appliance Parts Pros and they sent a GE Original gasket from their Fresno warehouse. To remove the old gasket just peel it away, it's only held in by a single channel, then clean the area. Prior to installing the new gasket, warm it up in the dryer and decompress the gasket (on a flat surface) and hold it in a decompressed state until it cools. This will help the gasket comply with the surface once installed. To install the new gasket just press it into the channel, no tools required and the door can be in place. To make it easier, you will want to turn off the freezer by setting the temp for the freezer high (this will also turn off the refrigerator) but before doing this move the food into a portable cooler. Once installed turn down the temp for the freezer (0-3 Degrees F) and fridge (34-36 Degrees F) and put a super thin layer of vaseline on the face of the gasket to ensure a good seal.
