This DIY repair guide explains how to replace the walking board on a treadmill. The walking board–also called a deck–provides a sturdy platform for walking and a smooth surface for the walking belt. If the walking board wears out, friction between the board and the belt increases, and the treadmill will feel sluggish or will stick. Replace a worn or damaged walking board with the manufacturer-approved replacement part.
Follow the steps in this repair guide and video to replace the walking board on Weslo, Proform, Weider, Lifestyler and Horizon treadmills.
