The short answer
A dryer that tumbles without heat has usually lost the supply to its heat source rather than the heat source itself, and on an electric machine that often means half its power. The order below starts with supply, then goes to the safety devices, then to the element or burner. On a Eurodesign dryer the place to start is the vent and the thermal fuse it protects, because the moisture-sensing and control chain decides when this dryer stops, so it outranks the heater on the list.
What you actually observe
- Clothes come out damp and cool after a full cycle — Same fault with the evidence at the end rather than during.
- It heated yesterday and not today, with no warning — Sudden and complete loss of heat points at a fuse, a breaker leg or a burner ignition rather than at gradual wear.
- On a gas machine, no click or no flame at the start — The ignition sequence is not completing, which is a different chain from the electric one.
- NEAR MISS: it heats but the laundry is still damp — That is a cycle or airflow fault.
Causes, most likely first on this brand
- A blown thermal fuse after a vent restriction — When the vent blocks, the machine overheats and a one-shot thermal fuse opens to protect it. Ranked first on a Eurodesign dryer: these are built-in units fitted into a cabinet opening, where the install decides the door line, the clearance and the drain fall, and where nothing inside the machine has usually failed at all.
- An open cycling thermostat or high-limit — The thermostats decide when the element runs. Where it sits here: ranks with the fuse because they share a cause and a circuit, and they are usually tested together.
- A failed heating element, igniter, flame sensor or gas valve — On an electric machine the element is a coil that eventually breaks. Where it sits here: the genuine component failure of the set, and the only reason it is not first is that supply and fuse faults outnumber it.
- An air-fluff or no-heat cycle selected — Every dryer has a no-heat setting and it is one click from the ones people use. Where it sits here: trivial, free, and worth ten seconds before anything else is considered.
Check in this order, and why
- Start at the vent and the thermal fuse it protects — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Check the cycle selected and the temperature setting — Ten seconds and it removes the most embarrassing possible outcome of a service visit.
- Check both breaker legs or the gas shut-off — On an electric machine switch the double breaker fully off and on again.
What an owner can safely do
- Select a high-heat cycle deliberately — Set the machine to a cotton or high-heat programme rather than air-fluff, and run it for a few minutes with a hand at the vent.
About 10 min
- Reset both breaker legs — Switch the double breaker fully off, wait, and switch it firmly back on.
About 10 min
- STOP HERE before testing fuses, thermostats or elements — All of those are meter checks on a dismantled machine, and on a gas dryer the burner assembly is not an owner area at all.
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. Never bypass a thermal fuse or a high-limit thermostat to restore heat: those devices open because the machine was overheating, and defeating one turns a lint problem into a fire. On a gas machine, if you smell gas: do not switch anything on or off, leave the building and call the gas utility or emergency services from outside. Do not look for the leak yourself.
When to call a technician
Call once the supply, the cycle and the vent are all proven good and the machine still runs cold. Everything left on the list is behind a panel and is tested with a meter, and on a gas machine the burner train is licensed work. Call immediately if the machine has smelled hot or scorched at any point.

What this page does not cover
This page covers Eurodesign dryers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: element ratings, fuse and thermostat part numbers and the burner assembly references, all of which differ by family.
