The Whirlpool WPW10250667 Balance Spring supports stable tub movement and balanced washer performance during spin cycles. This replacement balance spring is designed to connect within the washer’s suspension system, providing controlled tension that keeps the tub properly positioned as the load moves. By absorbing and managing movement, it reduces excessive shifting, vibration, and uneven motion during operation. A worn, stretched, or damaged spring can contribute to an unstable tub, increased vibration, or unusual movement during washing.
