The answer, before the detail
A Black+Decker BLD dryer that has become noisy is usually telling you about the parts that carry the drum or the air: rollers, glides, an idler pulley, or something hard in the blower. The first two checks below are done with the machine off and the drum turned by hand, which is where this page starts. Settle the build before the ranking applies: these models divide on a gas pipe behind the machine.
What the owner actually sees
- A thump once for every turn of the drum — Count it against the drum and you have already halved the list.
- A squeal or chirp that rises with the machine — A dry roller, an idler pulley or a belt riding badly.
- A hard rattle that comes and goes — It often changes completely when the load changes.
- A dragging noise throughout the cycle — The drum is running on something it should not be, and that is a stop-now noise rather than a book-it-later one.
- A low roar that used to be a hum — Slow arrival is characteristic of wear rather than damage.
- NEAR MISS — a buzz with no drum movement at all — That is a start or belt fault and belongs on the page for a machine that will not start.
Causes, ranked for the BLD build
- Drum rollers, glides or the drum seal are worn — It leads on these models because the supports carry the whole drum and wear slowly enough that the noise arrives as a gradual rumble nobody acts on. A drum that can be moved by hand more than it used to is the confirmation.
- The belt or the idler pulley is worn or riding badly — It ranks just under the supports because the two are reached in the same teardown, so a technician checks both.
- Something hard has reached the blower wheel — It is ranked by how fast it can be proved: it either rattles or it does not.
- The machine is out of level, or on an unstable floor — It is placed here because it is free to check and it explains a surprising share of complaints on stacked and cupboard installations.
- The motor or its bearings — It comes last deliberately: every cause above is likelier, cheaper and audible from outside.
The order that finds it fastest
- Decide what the noise tracks — drum or motor — Once per revolution is the drum path; continuous and rising is the belt and pulley. Nothing else narrows it as fast.
- Turn the drum by hand with the machine off — Power off first. Roughness, drag or a drum that lifts too easily all point at the supports.
- Check the lint path and the filter housing — It also removes the commonest cause of overheating while you are there.
- Rock the cabinet and check the feet — Free, fast and worth doing before anything is opened.
Power off first
Safety
Unplug the dryer or switch off its breaker before any panel comes away, and treat a gas model as gas work: if you smell gas, do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself.
When to call a technician
The line falls at the cabinet panel. Clearing the lint housing, levelling the feet and emptying pockets are owner work and account for most rattles. Rollers, glides, the idler pulley, the belt and the motor are not — they need the machine opened, and the noises that come from them get worse rather than better with use. Book the call while it is still a noise rather than a breakdown.
