Dryer drum does not turn, but the motor can be heard humming or the dryer stops shortly after starting.

Safety first: Unplug the dryer before removing any panels. Avoid placing hands near the motor or belt path when power is connected.

• Check drum rotation by hand: Open the door and try to rotate the drum. If it is very stiff or jammed, suspect a mechanical obstruction or seized bearing.
• Inspect belt: Remove the top cover and look for a loose or broken belt. If the belt is off the drum or broken, replace it.
• Check rollers and idler: Access the drum support rollers and idler pulley. Spin each by hand; replace any that are noisy, rough, or seized.
• Look for obstructions: Inspect the gap between the drum and front/rear bulkheads for trapped items (e.g., bra wires, coins). Remove any foreign objects.
• Reassemble and test: After replacing worn parts and clearing obstructions, reassemble and run a test cycle to confirm normal drum rotation.
