The short answer for the DC models
On the AEG DC dryer models, a machine that runs without heat still leads to the same place as the brand-generic article: how this machine makes its heat. What changes here is what sits behind it — a thermal fuse or cut-out has opened comes up to second, because the two codes in this family share a platform, so a cause that is real on one is real on both.
What you observe on these models
- It heats on one setting and not another — Air, refresh and delicate settings all reduce or remove heat by design.
- The room gets damp and warm while it runs — The moisture is going into the room rather than outside, which is an airflow story.
- The drum tumbles and the air stays cool — Motor fine, heat absent: that split is the whole of this page.
- NEAR MISS — it is too hot rather than not hot enough — Stop using it and call; an overheating dryer is not a wait-and-see fault.
Causes, most likely first on the DC family
- How this machine makes its heat — Where a dryer heats by moving heat rather than by making it, there is no element to fail and no thermal fuse story to tell. Ranked first on the DC models.
- A thermal fuse or cut-out has opened — The device did its job. Second.
- The programme has no heat in it — Air dry, refresh and some delicate cycles run cool by design. Third.
- The control or the timer — The most expensive place to guess. Last, and that is the point of the order.
- Body: The spine for the DC family records two model codes that share their stem and differ only in what follows it, so the two behave as one platform for this fault. Where this departs from the brand-generic ordering: the cause that moves up to second on these models is this one — a thermal fuse or cut-out has opened — while the brand-generic lead keeps the top.
Check in this order on the DC models, and why
- Feel the exhaust at the outside outlet while it runs — First: Weak flow names the airflow cause; strong flow with cool air moves you to the heat source.
- Take the filter out and hold it up to the light — Second: A screen you cannot see light through is blinded, even when it looks clean.
- Establish whether heat ever appears, even briefly — Third: Heat then nothing is a cut-out; never any heat at all is supply or the heat source.
Before you open anything
Safety
Nothing comes off a dryer until the breaker is off — a capacitor holds its charge and the element block stays live until the supply is broken. Treat the lint inside the cabinet as fuel and remove it. If your machine burns gas, shut its valve before touching anything behind it, and if you smell gas do not switch anything on or off: get out and call the gas utility from outside.

When to call a technician
Call when the duct is clear end to end, the filter is washed, a heated programme is selected, the breaker is confirmed on both poles and there is still no heat — that puts it at the element or the gas train, the thermal devices or the control. Call immediately and do not restart the machine if you smelled burning before the heat stopped, or if the cabinet came out unusually hot. On the DC models the line sits where the check stops being one you can make from outside the cabinet. When you book, say that the machine is built in if it is.
