The WP40111201 is a genuine OEM dryer drive belt for Maytag and compatible dryers. This belt wraps around the dryer drum, idler pulley, and drive motor pulley to rotate the drum during operation. It is constructed from high-strength, heat-resistant rubber with multiple ribs for quiet, long-lasting performance. Typical lifespan is 6–12 years; failures are most often due to cracking, fraying, stretching, or breakage. Symptoms: drum not turning, motor runs but drum doesn’t spin, squealing noises, or dryer stops mid-cycle. IMPORTANT: Only use OEM belts for correct fit and tension. CRITICAL: Disconnect power before servicing.
