Installation notes
Belt sizes are precise. Match the length and the rib count exactly; a near-size belt will slip or overload the motor. The model number is on the rating plate, usually inside the door or on the back panel. Compare it with the model list before you buy. The exploded parts diagram is included in the product photos so you can confirm the item number.
