My Maytag Atlantis top load washer recently started having a burning rubber type of smell. It still goes through a full cycle with no problems and the belt under the washer seems in good shape. I opened the front and the motor seemed ok (although I admit I don't know what I'm looking for), however if I run a load of laundry, there's a smell of burnt rubber after the load is done. I have made a point of trying not to use it often, but I have no idea what's wrong. The belt seems ok and the agitator is spinning fine, it's just the smell. (once there was a thin bit of smoke, but only once). Any ideas?
