Whirlpool makes multiple dryer designs, and belts aren’t one-size-fits-all. The correct part depends on the model number and drive layout. Even when belts look similar, the width, length, and routing can differ.
Locate your dryer’s model and serial information label. It’s commonly on the door frame or behind the door opening. Write down the model number exactly, then use it to identify the correct replacement belt and any matching tension hardware.
What to have on hand before you start
Beyond the replacement belt, gather the tools you’re likely to need. Most belt jobs involve basic hand tools—typically a nut driver or socket set and a Phillips screwdriver. A putty knife or plastic panel tool can help you manage clips or prevent cosmetic damage when separating panels.
It’s also smart to have a smartphone ready. Take reference photos as you remove parts. Those images become your routing guide when you install the new belt.
