The short answer
On the BRDH family a dryer that tumbles without heat has usually tripped a protective device rather than broken one: a thermal fuse or a limit thermostat opens when airflow is restricted, and it does not close again by itself. Replacing it without clearing the vent buys you one load before the same fault returns.
What you actually observe
- The drum turns for the whole cycle and the load comes out damp and cool — Motor and timer are fine; the heating circuit is not being energised or has been cut.
- Clothes are hot but still damp at the end of a cycle — That is airflow, not heat — the machine is making heat it cannot get rid of, along with the moisture.
- NEAR MISS — no drum movement and no heat at all — That is a power, door-switch or belt fault and it belongs on the will-not-start page.
Causes, most likely first on the BRDH family
- Blocked or restricted vent duct — First on these models, and first by a wide margin, because everything below it is usually a consequence of it. Lint accumulates over months in the duct rather than in the filter, and the machine slowly loses the airflow it needs to carry moisture away. A single model means one belt path and one heater layout, so this ranking is the order for that build rather than a family average.
- Thermal fuse or high-limit thermostat open — Second, and it is the part that actually stops the heat. A one-shot fuse does not reset, so a dryer that runs cold after a hot spell has almost certainly opened one.
- Heating element failed open, or an igniter fault on a gas machine — Third. Elements do fail on their own, but on these models a failed element and a blocked vent often arrive together, because heat that cannot escape shortens the element life.
- Cycling thermostat out of calibration — Fourth. It produces lukewarm drying rather than no heat, and it is easy to confuse with a partially restricted vent.
- Timer, control board or selector giving no heat command — Last. Real but uncommon; suspect it when the fuse, the element and the vent all test good.
Check in this order, and why
- Disconnect the vent at the back and run the dryer for a minute — If it heats with the duct off, the duct is the fault and no part needs buying. This is the highest-value test on the page.
- Clean the lint filter and the filter housing, then check the outside vent hood — A flap held shut by lint restricts the whole run and is the commonest blockage point.
- Confirm both legs of the supply on an electric machine — Last. A dryer on one leg of a two-pole supply tumbles normally and will never heat — and it looks exactly like a failed element.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. On a gas machine, shut the gas valve before disturbing any connection, and if you smell gas do not switch anything on or off: leave the building and call the gas utility or emergency services from outside. Never run a dryer with the vent disconnected for longer than the test itself, and never bypass a thermal fuse.

When to call a technician
Call when the vent is proven clear and the machine still runs cold, because what is left is the fuse, the element, the gas train or the supply, and all of those need a meter. Call immediately if you smell burning, or if a fuse has opened twice — a fuse that keeps blowing is a machine that keeps overheating, and that is a fire risk rather than a parts problem. On a gas model, anything at the valve, the igniter or the burner is licensed work.
