The short answer
A Black+Decker BCED dryer that tumbles without heating is usually short of one of two things: half its electrical supply, or the airflow that keeps its thermal limits closed. On these models the supply comes first, because an electric dryer can lose one leg of its circuit and still turn the drum perfectly. Whether yours is gas or electric decides the whole list, so establish that before anything else.
What you observe on these models
- Cycles finish with everything still wet — Cold tumbling for a full cycle leaves the load barely changed.
- A gas model that has been moved or serviced recently — Free to check and very often the answer.
- A burning or hot smell with no heat — Switch it off and leave it off.
- NEAR MISS — warm air, long cycles — That is an airflow and sensing fault, and it has its own page.
Most likely first on this family
- Half the electrical supply is missing, or the gas is off at the valve — It leads because it is the one cause that produces a perfectly normal-looking machine with no heat, and because both versions are checked without a tool. A standard household branch circuit is 15 A or 20 A at 120 V and a large appliance circuit is typically 30 A or higher at 240 V, so an electric dryer has two poles to lose and only one has to go.
- A cycling thermostat or thermistor reading wrongly — It is ranked here because it is only reached once the free checks are done. It is a part swap in a service visit rather than a repair you make.
- The heating element, the igniter or the gas valve coils — It ranks below the supply and the vent because both of those are free to rule out and this is not. Either way the confirmation is a technician-side one.
- The timer or the control board — Last, as the least likely of the five and the one with the fewest external signs. That is a diagnosis for a technician rather than a guess to buy against.
Check in this order, and why
- Look behind for a gas pipe or a heavy cord — A gas pipe and shut-off valve, or a heavy cord on its own circuit — the two lists barely overlap.
- Reset the breaker fully, or confirm the gas is on — On gas, check the valve behind the machine is in line with the pipe.
- Prove the air path before anything else mechanical — Feel for flow at the outside hood while it runs.
- Ask whether drying had been slowing for weeks — The history is diagnostic and free.
Before you open anything
Safety
Power off first — unplug it, or trip the breaker where the machine has its own circuit. A standard household branch circuit is 15 A or 20 A at 120 V, and a large appliance circuit is typically 30 A or higher at 240 V, so an electric dryer usually has two poles to switch and both matter. On a gas model, if you smell gas, leave the building and call the gas utility or 911 from outside rather than hunting for it. Lint is what burns in a dryer: clear it rather than working around it.
Where the owner job ends
The line falls where the cabinet does. Breakers, gas valves, ducts and hoods are owner work and account for a large share of no-heat calls. Elements, igniters, valve coils, thermostats and thermal cut-offs are not, and a cut-off that has opened should have the reason behind it found rather than the part simply replaced.
