I have a frigidaire front load from Sears. First the door hinge broked and the service people blamed that on use and would not cover the over $300 bill. We used the washer as designated. The detergent draw had a crack in it. Now the rubber seal around the door is torn. The machine is less than three years old. I need to know how to replace teh seal. This is the second machine I bought from Sears that did not last and the service contract would not cover.
