Speed Queen Dryer Drum Not Turning: Belt, Idler, and Motor Diagnosis
Quick Answer
Speed Queen dryers use a heavier-duty belt and idler pulley than consumer brands. The belt is wider and thicker, lasting 8-10 years vs 5-7 for consumer belts. When it does break, the motor runs but the drum doesn't turn. Speed Queen's belt switch cuts motor power when belt breaks (same as Whirlpool).

When it does break, the motor runs but the drum doesn't turn. Speed Queen's belt switch cuts motor power when belt breaks (same as Whirlpool). The drum rollers on Speed Queen are sealed bearings rated for commercial use - they last significantly longer than consumer brand rollers. If the drum barely turns by hand (heavy resistance), the bearings in the rear drum support have seized.
