We have a Kenmore top freezer refrigerator that we use as an extra in our garage. Its a smaller, less expensive unit than is typically the main household unit. Kenmore model # 253.6580250A.It seems the seal has weakened for the freezer, as the door will pop open when the refrigerator door is shut. I should note that the seal doesn\'t show any particular signs of obvious wear. It also seems to be adheared to the door well, not falling off by any means.Can those seals be replaced? Is it the seal that holds those doors in place when the other one below is being used? It is difficult to do, or can those be easily replaced. It doesn\'t look or seem complicated.
