The short answer
A Black+Decker BFLD dryer that will not start splits by what happens when you press the button: complete silence is a power or door question, and a hum with no drum movement is a belt or a motor one. On these models the door switch leads — the machine is built not to run with the door open, and a switch that has drifted looks exactly like a dead dryer. Decide which noise you have before anything else. The BFLD key covers more than one build, and for this fault the difference shows in whether your unit has the lint filter in the door opening.
What the owner actually sees
- Nothing at all — no lights, no sound — A power question first: the outlet, the breaker or the cord.
- It responds to the buttons and then does nothing — Power is present and something is refusing the cycle — usually the door or a lock.
- It hums but the drum does not turn — A broken belt or a seized drum: the motor is trying, and nothing is following it.
- A single click and then nothing — Often a door switch or a start switch making contact and the machine declining.
- It starts and stops after a few seconds — Note how warm the machine is when it happens.
- NEAR MISS — tumbling with cold air — That is a heating fault on a machine that has started, which is a different page.
Causes, ranked for the BFLD build
- The door is not latching, or the door switch has drifted — It ranks first anywhere the panel lights up and the drum simply never moves.
- A broken belt, or a drum that has seized — It is ranked by pattern: the hum is what puts it here.
- A child lock or a delayed start is set — It is placed high because it costs nothing to rule out and it imitates a control fault exactly.
- Power: the breaker, the outlet or the cord — It rises on an electric machine especially, where a double breaker can be half tripped.
- The start switch, the thermal fuse or the control board — Last of the five, because it is the only one that needs the cabinet open and the four above explain most cases.
The order that finds it fastest
- Classify the response: silence, a hum, or a click — Silence is power or door; a hum is the belt or the motor; a click is usually a switch declining.
- Press the door firmly shut and retry — A machine that runs when you hold the door home has named its own fault.
- Prove the supply before suspecting the machine — Switch a double breaker completely off and back on; a half-tripped pole looks perfectly normal.
- Feel whether the drum spins freely or not at all — Free-spinning with a humming motor is a broken belt; a drum that will not move is seized.
Before you open anything
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.
Where the owner job ends
Call when the outlet is proved with something else and the machine is still dark, when the door is proved and it still refuses, or when the motor hums without the drum turning. Those leave the switch, the fuse, the belt and the motor, all behind the cabinet.
