The short answer
A noisy the BRDH family dryer is usually reporting friction in the drum supports. On these models the thump, the squeal and the scrape each come from a different part, and identifying which you have is most of the repair.
What you actually observe
- A rhythmic thumping that keeps time with the drum — Something on the drum circumference: a flat spot on a roller, or a seam riding a worn glide.
- A high squeal that rises with the drum speed — A dry idler pulley or a dry rear bearing. It usually starts intermittently and becomes constant.
- A metallic scrape or grinding from the front or rear of the drum — A worn drum glide or felt seal letting the drum contact the bulkhead. It will mark the clothes before it stops the machine.
- NEAR MISS — a hum with no drum movement at all — That is a seized blower or a broken belt and it belongs on the will-not-start page.
Causes, most likely first on the BRDH family
- Drum support rollers worn or flat-spotted — First on these models: the rollers carry the whole loaded drum and they wear steadily, producing a thump that keeps time with rotation and gets worse under load. A single model means one belt path and one heater layout, so this ranking is the order for that build rather than a family average.
- Idler pulley dry or its bearing failing — Second. It tensions the belt and it is the part that squeals. The noise appears first on cold starts and then all the time.
- Drum glides or felt seals worn through — Third. Once the glide is gone the drum touches the bulkhead, which grinds and also transfers marks to the load.
- Foreign object in the drum or the blower housing — Fourth, and the cheapest to fix: a coin past the filter rattles in the blower wheel every revolution.
- Motor bearing or blower wheel failing — Last. A motor that has become noisy is usually still driving the drum, but it is the branch where the repair stops being cheap.
Check in this order, and why
- Turn the drum by hand with the machine unplugged — Roughness, catching or a gritty feel points straight at the rollers or the rear bearing and costs nothing to test.
- Note whether the noise keeps time with the drum or with the motor — Drum-speed noise is rollers, glides or seals; motor-speed noise is the idler, the blower or the motor itself.
- Inspect the drum seam and the bulkhead for witness marks — Last, because it needs a panel off — but bright metal where the drum has been rubbing confirms a worn glide immediately.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never reach into a drum that is turning, and never run the machine with the front panel off to watch the belt. On a gas machine shut the gas valve before pulling the appliance out, and if you smell gas leave the building and call the gas utility or emergency services from outside.

When to call a technician
Call when the noise is a grind that marks the laundry, because a drum riding on its bulkhead damages both the drum and the clothes. Call when the drum feels rough or catches when turned by hand, which points at rollers or a rear bearing and needs the cabinet opened. A rattle traced to a coin, and a squeal that disappears after the idler is replaced, are ordinary maintenance rather than a failing machine.
