The short answer
A compact dryer that tumbles without heating points first at one thing: the lint filter is blinded. Next on the list: the duct is blocked and the machine is cutting itself out. The element is at the bottom of this list on purpose — it is the part owners blame first and the one a technician checks last.
What you observe
- The drum turns normally and the clothes come out damp — Tumbling without heat is a very different fault from not running at all.
- The filter looks clean and the machine still runs cool — Looking clean and being clear are different things.
- Clothes come out damp and the drum is turning normally — Tumbling without heat is the classic signature of a cut-out.
- The air at the outlet is room temperature — Not cool, not warm — exactly ambient.
- NEAR MISS — it heats but the clothes still come out damp — That is a drying performance or sensor question, and it belongs on a different page.
Causes, most likely first on this machine
- The lint filter is blinded — First, because it is the one part the machine expects you to clean and the one place a film builds invisibly.
- The duct is blocked and the machine is cutting itself out — Ranked here because a restricted duct causes more no-heat calls than every component on this list put together.
- The heating element has gone open circuit — Ranked here because it is real, but a blocked duct produces the same symptom far more often and for free.
- The cycling thermostat is holding the element off — Last, and a service part — but the partial-heat pattern is the clue worth recording.
Check in this order, and why
- Pour water on the lint screen and see whether it runs through — A clean-looking screen can be sealed by softener film.
- Disconnect the duct and run the machine briefly on heat — Strong warm air at the outlet means the machine is fine and the duct is not.
- Note whether there is any warmth at all at the outlet — No warmth whatever, with good airflow, points at the element.
- Note whether there is some heat or none at all — Some heat means a control; none means a supply or an element.
What an owner can safely check
- Run the machine for a few minutes and feel the exhaust air — Warm, ambient or hot decides everything that follows.
About 10 min
- Wash the lint screen in warm soapy water and dry it — Repeat every few months if you use fabric softener.
Tools: warm water, brushAbout 15 min
- Pull the duct off the back and check it end to end for lint — Check the outside flap too — it is where lint packs hardest.
Tools: vacuum, torchAbout 45 min
- STOP HERE before opening the heater housing or testing a fuse — That means live terminals on a high-current circuit. Service call.
Before you open anything
Safety
Unplug the machine or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and a dryer that has just cut out on temperature is hot inside long after it is silent. Never run the machine with the duct disconnected for longer than the few seconds a test takes — exhaust indoors carries lint and moisture into the room. And never restart a machine that has cut out on temperature until it is fully cold.
When to call a technician
Call once the airflow path is proven clear end to end and there is still no heat — what is left is the element, a thermostat or the supply, and all three are meter work on a high-current circuit. Call immediately if you smell burning, if the cabinet is too hot to touch, or if the breaker trips when the machine calls for heat.

What this page does not cover
This page is written for the brand and the machine class, not for one family or model line. Where a family- or model-specific page exists for your machine, that page is the more specific answer. Deliberately absent: duct diameters, capacity figures, glide and belt part identifiers and wiring colours, which differ between the wall-vented and window-vented families.
