Dryer drum turns but there is a loud squealing noise during operation

Safety first: Unplug the dryer before removing panels. Sharp edges inside the cabinet can cause injury.

• Isolate the noise: Run the dryer briefly to identify whether the noise is from the front, rear, or bottom, then disconnect power.
• Access drum supports: Remove the front panel and drum to expose the idler pulley, rollers, and glides.
• Inspect idler pulley: Spin the idler by hand. If it squeals, wobbles, or feels rough, replace it.
• Check drum rollers: Spin each roller. Replace any that are noisy or have flat spots.
• Inspect drum glides: On models with front glides, check for excessive wear or missing glide material. Replace as a set if worn.
• Reassemble with correct belt routing: Ensure the belt is properly aligned on the drum and pulleys before reassembly.
