One further note regarding odd belt breakage on this model....if your vent is restricted and the dryer has been cycling on hi-limit for awhile, the belt is being subjected to a concentration of high heat along the top of the drum. As you know the heater is just under the main top in the left corner. All residual heat is trapped under the main top after the dryer has shut off. So is the top edge of the drive belt, wherever the drum has stopped. If your dryer symptoms are accompanied by a very hot main top during operation, your exhaust may be a factor. FYI, Maytag does not allow foil duct on their products, as noted on the sticker on back of the dryer.
