These checks are safe for homeowners. Do not attempt to open sealed refrigerant systems, touch electrical components behind access panels, or work on gas lines — always call a licensed technician for those.
Open the dryer and check for items that shouldn't be there. Bra underwires, coins, and small hard objects fall between clothes and cause metallic banging. Check the drum seal area (the rubber gasket around the door opening) for wires or debris caught in it.
Shoes, bras, and items with metal hardware make significant noise when tumbling freely. Use mesh bags for these items or place a couple of tennis balls in with shoes to cushion the impact. This doesn't fix a mechanical noise, but immediately quiets hard-item banging.
Pay attention to whether the noise happens throughout the cycle, only when the drum is turning, only at certain temperatures, or only at the start. A squeal only during spin points to drum slides; constant noise regardless of drum spin points to the motor or blower wheel. Knowing this tells a technician a lot.
Squealing in a dryer almost always points to a friction problem: worn drum slides (the plastic glides the drum sits on), a dry or worn idler pulley, or a fraying drive belt. These are all wear items that have a normal lifespan of 8–12 years. The squeal will worsen until the part fully fails — schedule service before it causes secondary damage.
It depends on the noise. A rhythmic thump from shoes in the drum — fine to run. A deep grinding noise from a failing drum bearing — stop using it. A bearing that seizes can prevent the drum from spinning at all, and the motor will keep running against the load until it fails too. Grinding noises warrant prompt service.
A squeal only at startup that stops after a minute or two usually indicates a worn idler pulley or drum bearing that needs a moment to warm up and seat. The squeal goes away as friction surfaces warm slightly. This is an early warning — the noise will eventually become constant as the wear progresses.
Dryer drum slide/glide replacement runs $100–$180. Idler pulley replacement is $90–$160. Drum bearing replacement is $120–$220. Blower wheel cleaning or replacement is $100–$170. HomeHeroes diagnoses the noise source and provides an upfront quote before any work begins.
