What this usually is
A dryer on this family that tumbles without drying is usually failing to move air rather than failing to make heat. Cycle times that have grown gradually over months are an airflow story told slowly. Only the heat source and its controls take this off the owner list. Part numbers are left to the table above; the text stays with the method, which is what holds.
What you actually see
- A burning or scorched smell during the cycle — Stop the machine. Lint at temperature in a restricted cabinet is the fire risk this page exists to prevent.
- The load comes out hot but still damp — Heat is being produced and moisture is not leaving. That is an exhaust problem, and it is the commonest finding here.
- The load comes out cool and damp — No heat at all. A different half of the page: supply, element or igniter rather than airflow.
- The outside of the machine is unusually hot — Heat that cannot leave through the duct leaves through the cabinet instead. Worth treating as urgent.
- The vent hood flap outside barely moves — The clearest airflow test available and it needs no tools at all.
- NEAR MISS — the drum does not turn at all — A machine that will not tumble is a different fault path with its own page for this family.
Ranked causes for these models
- Restricted exhaust duct, vent hood or lint path — First on this roster and the commonest finding on the page. Crushed flexible duct behind the machine, a long run with too many bends, a hood flap that no longer opens, or years of lint in the run all cut airflow until a cutout opens.
- Thermal cutout or cycling thermostat opened — Heat that works and then stops is the classic signature. The device is usually doing its job: it opened because the cabinet got hotter than it should, and that means air was not moving.
- Half supply — one leg of the circuit lost — An electric dryer draws its motor from one leg and its heat from both. Lose one and the drum turns perfectly while nothing gets warm, which is the single most misleading symptom here.
- Control, timer or moisture sensor fault — Last. This explains a machine where the duct is clear, the supply is good and the cutouts are closed, and it is where owner diagnosis runs out.
What to check first, second, third
- Clean the lint filter and the housing below it — The filter is routine; the housing is not, and lint packs into it where nobody looks.
- Feel the load at the end of a cycle — Hot and damp means heat is being made and air is not moving. Cool and damp means heat is not being made at all.
- Watch the vent hood outside while the machine runs — A flap that barely lifts is the clearest airflow test available and it costs nothing.
- Check both halves of the breaker for an electric machine — A dryer that tumbles and does not heat has often lost one leg of its supply, and the breaker looks on.
Safety before diagnosis
Safety
Kill the supply before anything else happens: unplug it, or switch the breaker off. A capacitor can hold a charge long after the power has gone.

When this stops being owner work
Clean the filter, clear the duct and check the breaker before calling anybody: between them they explain most of these. Call when a machine with clear airflow and a good supply still produces no heat.
