The short answer
No heat on the BDPB line has a short list of causes — airflow, a thermal cut-out, the heating element or its relay, and on a gas machine the ignition sequence. Airflow leads the list because it is both the most common cause and the reason the other parts fail in the first place. This is a wide family, and the order below is what its construction dictates rather than what the brand as a whole does.
What you observe on these models
- The drum turns but the load comes out cold and damp — The mechanical half is fine and the heating circuit is not being energised, or is being cut as soon as it heats.
- Cycles take much longer than they used to, then stopped heating entirely — The gradual airflow decline that precedes almost every heating failure — the blockage built over months before it tripped anything.
- The outside of the machine or the exhaust hose is unusually hot — Heat that cannot leave the machine, which is the state that opens a thermal cut-out.
- It heated for one cycle after a reset and then stopped again — A resettable protector opening repeatedly, which means the underlying airflow problem is still there.
- NEAR MISS — the drum does not turn either — That is a motor, belt or start fault rather than a heating fault, and it belongs on a different page.
Causes, most likely first on the BDPB line
- Thermal fuse or high-limit thermostat open — First, and the cheapest to rule out. It ranks second because it is the direct cause of the symptom even when it is not the underlying problem.
- Restricted exhaust duct, hose or lint screen — Next most likely on these models. A dryer works by moving air, and a restricted duct raises the internal temperature until a protective device has to act.
- Heating element or its relay failed — Third — worth checking once the two above are clean. A machine that has always vented well and suddenly runs cold, with a clear duct, is this rather than an airflow fault.
Check in this order, and why
- Suspect an open protector once airflow is proven — A machine that runs cold with a clear duct has usually already opened a one-shot fuse. Replacing it without clearing the duct guarantees a repeat.
- Clear the lint screen, then check the whole duct to outside — Pull the machine out, disconnect the hose, and look for a crushed section behind it and a blocked flap at the outside wall. Run the machine briefly with the hose off and feel the airflow.
- Check for heat at the element with the duct clear — On an electric machine a failed element gives a cold cycle with everything else normal. A breaker that trips on heat instead points at a grounded element.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off. Never run the machine with the drum panel removed to observe a fault, and clear lint from the cabinet while you are inside it: lint against a heater is how dryer fires start.

When to call a technician
On the BDPB line everything in the air path is yours and everything in the heater circuit is a service call. On a gas machine the ignition components are licensed work in every case. Do not replace a thermal fuse and put the machine straight back into service — the fuse opened for a reason, and if the duct has not been cleared it will open again on the next load.
