The Frigidaire 131302800 vane screw helps secure the drum vane in place for proper washer performance. This small but essential fastener is designed to attach the vane firmly to the inner drum, ensuring it remains stable during wash cycles. It works by holding the vane tightly so it can effectively lift and tumble clothing as the drum rotates. A loose or missing screw can cause reduced agitation or unusual noise. By keeping the vane properly secured, this component supports consistent cleaning action, helps prevent internal wear, and contributes to smooth and reliable washer operation. It offers a simple solution for maintaining effective drum function.
