West Bend 4065 Bread Maker Locking Up and Not KneadingMy bread maker, a West Bend 4065, is locking up and not kneading. The motor is trying, but the paddle won't turn. This has happened before. The belt is not broken. Do the gears need oil/grease? I have had this unit many years, but it only gets used 1-4 times a year. I would like to use it more.
