Whirlpool WP6-3705180 Dryer Idler Arm and Shaft
The Whirlpool WP6-3705180 Idler Arm and Shaft maintains proper tension on the dryer drive belt, supporting smooth drum rotation during operation. This replacement component works with the belt and drive system, allowing the idler pulley to move and maintain the tension needed to transfer power from the motor to the drum. Proper belt tension helps the drum rotate consistently as clothes tumble during the drying cycle. A worn or damaged idler arm and shaft may cause belt slipping, unusual noises, or interrupted drum movement. Replacing the faulty component can restore proper belt tension and support normal dryer performance. Designed for compatible dryer models, this part provides a practical solution for maintaining reliable drying operation.
