Dryer makes loud squealing or screeching noise during operation

Safety first: Unplug the dryer before disassembly.

• Isolate noise: Run the dryer briefly (if safe) to identify whether the noise occurs only when the drum turns.
• Inspect front glides: Remove the front panel and examine the felt and plastic glides where the drum rides. If they are worn through or missing, replace the glide kit.
• Check rollers: Access the rear drum support rollers. Spin each roller by hand; if they squeal, wobble, or feel rough, replace them as a set.
• Inspect idler pulley: Check the idler pulley for smooth rotation. Replace if noisy or seized.

Lubrication is generally not recommended on these parts; replacement is the proper repair for worn components.
