The short answer
On the Black Decker BFLD dryer an unfamiliar noise is usually something loose in the air path rather than a worn part. The BFLD table lists one model, so the same checks apply across the model list in the table.
What you observe
- A rhythmic thump once per drum revolution — Something on the drum or its support: a flat on a roller, a worn glide, or a seam catching.
- A metallic rattle or scraping that comes and goes — Usually a coin, a button or an underwire that has passed the filter and is loose in the blower housing.
- A high whine that rises with the cycle — A bearing under load — motor or blower.
- A squeal that fades after the first few minutes — A dry glide or a belt on a cold machine.
- NEAR MISS — noise with a drum that will not turn at all — That is a jam or a broken belt and belongs on the page for a machine that will not start.
Causes, most likely first on the BFLD family
- Coins, buttons and underwires in the blower housing — First on this family — the BFLD table lists one model — and a compact machine has a short path from drum to blower: anything that gets past the filter ends up where the fan spins fastest, producing a rattle that comes and goes with the load.
- Drum rollers and glides — Second: these wear flats and produce a thump exactly once per revolution. Turning the drum by hand with the power off finds them in seconds.
- Belt and idler — Third: a belt that has hardened or an idler whose bearing has dried gives a squeal on a cold start that eases as the machine warms.
- Motor and blower bearings — Last, and the only one that gets worse rather than staying the same. A rising whine that ignores load and does not settle is the one that needs a visit.
Check in this order, and why
- Turn the drum slowly by hand with the power off — First: roughness, a catch, or a thump you can feel names the rollers and glides before anything is opened.
- Empty the drum and check the filter housing for hard objects — Second, because coins and wires are the top cause and the cheapest possible fix.
- Run it empty and listen for whether the noise loads or not — Third — a noise that changes with clothes in the drum is mechanical support; one that does not is the blower or motor.
- Note whether the noise fades as the machine warms — Last of the free checks: a noise that fades is a belt or a glide and is rarely urgent.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the drum — a capacitor can hold a charge after the power is off. Never run the machine with a panel off or the door switch defeated to chase a noise. Lint is fuel: clear the filter and the air path whenever a panel is open. Get a second pair of hands before tipping or moving the cabinet.

When to call a technician
Call when the noise is a steady whine that rises with running time, ignores the load, and survives an empty drum — that is a bearing and it only worsens. Call immediately if the noise arrives with a burning smell or with a drum that has become hard to turn by hand.
