The short answer
For the Blomberg BLDV family of dryers, the generic answer is not wrong but it is not ordered for these models. What follows is the order that suits this platform. Dead panel and live panel are two completely different faults, and telling them apart takes one look. A dryer that starts and stops immediately is a different fault from one that never starts.
What you observe on these models
- Nothing at all happens when start is pressed — No sound, no light, no movement — a power question first.
- It runs only while the start button is held in — A start circuit or a centrifugal switch problem in the motor.
- It worked, then stopped, and now will not restart — A thermal device that has opened and not reset, or a motor that has overheated.
- NEAR MISS — it starts but makes a loud noise — A running machine is a started machine; the noise page applies.
Causes, most likely first on this family
- Start switch or motor start circuit failing — Fifth, and it is a distinctive enough symptom to be worth naming separately from a general control fault.
- Drive belt broken — Fourth, and it is identified instantly — a drum with a broken belt spins by hand with almost no resistance at all.
- Thermal fuse open — Third, and it is almost always the consequence of a restricted vent rather than a fault of its own.
- Why this order is not the brand-generic order — Because the layout differs. On these models the first check is chosen for what it eliminates per minute of work rather than for its standalone probability, and that is what separates a family-level ranking from a brand-level one.
Check in this order, and why
- Check whether anything on the panel lights up — A completely dead machine is a supply question. A lit panel means power has arrived and the refusal is downstream.
- Check the vent, even on a no-start — A thermal fuse opened by a blocked vent will stop the motor circuit on many machines, so the airflow check belongs here too.
- Turn the drum by hand — A drum that spins with almost no resistance has a broken belt. A drum that will not move at all has a mechanical obstruction.
- Why this order suits these models — The sequence above is chosen for this family's construction: each step is picked to eliminate as much as possible before anything has to come apart, so the checks that need no panel removed are done first and the ones that do are left until they are the only possibility remaining.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel or reaching into the lint path. On a gas machine, if you ever smell gas: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside.
When to call a technician
Call once the whole air path is proven clear and the fault survives it. Call immediately for any burning smell, any scorched lint, or any smell of gas — and in the gas case, leave the building first and call from outside without touching a switch.

What this page generalizes over
This page covers the Blomberg BLDV dryers as a family rather than one model. The models in it are close enough to share a diagnosis, but not identical, so where a detail depends on the individual model — a component position, a part number — it is not stated here. The family pages and the brand-level article linked below give the surrounding context.
