My SubZero 700BF freezer (two drawers) is about 12 years old. It keeps temperature OK, I believe, but the gaskets have developed a real mildew problem. I removed, bleach-cleaned and reinstalled them. Now I keep checking - a couple of times a day - and usually find water collecting on the gaskets. The rubber doesn't seem dried out or cracked, but perhaps it isn't as flexible as it should be? What else would account for this - or is it normal and unavoidable? My 700TR refrigerator of the same vintage has a similar problem. I've tried the old slip of paper test and the paper comes right out, although since these models are covered with wood paneling - in this case kind of complicated, old wood - that may not be a good test. Should I consider shimming the gaskets with felt or something else? Replace the gaskets? Or let it go? Perhaps for these gaskets 12 years is long enough. Thanks for advice.
