134719300 Dryer Drive Belt (5/16" x 79-1/4") – The essential fix for a Frigidaire dryer that won't tumble, has a motor that runs but the drum doesn't spin, makes squealing or thumping noises, or won't start at all. The drum belt is a long, thin black belt that wraps around the outside of the dryer drum and connects to the motor pulley and idler pulley — it's what makes the drum spin when the motor runs. Over time, the belt stretches, cracks, frays, glazes, or breaks completely from constant heat exposure and use. When the belt breaks, the motor runs but the drum doesn't turn — you'll hear the motor humming but clothes won't tumble. A worn belt that's slipping or glazed causes squealing, squeaking, or chirping noises during operation. If your dryer runs but the drum doesn't move, you hear unusual noises during tumbling, or you found a broken belt when you opened the cabinet — this is the part you need. This genuine OEM Frigidaire/Electrolux belt directly replaces 137315300, 7134719300, 134503900, 134163500, and 134163400. Fits Frigidaire, Electrolux, Kenmore, electric and gas dryers. Easy 20–30 minute DIY repair that gets your dryer tumbling again.
