My mother has a stackable Kenmore washer and dryer. I'm not able to locate any booklets on the model around the house. Currently every time we attempt to use the dryer... within a matter of seconds it begins this horrible high pitched squeaking. She has ordered a new belt in hopes if we replace it, it'll end the torture. However, when my brother had stopped by to replace it, he said it was fine, and the "inside" just needed to be cleaned out. Hmph! The squeaking continues! Is it the belt? Could it be something else? I tried a little lube oil. I NEED THE DRYER! Help me please!
