The short answer for the DHP models
On the AEG DHP 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 — the heating element, or the igniter and gas valve comes up to second, because this family is one model rather than a range, so the ranking can be specific where a brand-wide one has to hedge.
What you observe on these models
- There is heat at the start and then none — A cut-out opening as the cabinet warms, which points upstream at airflow.
- Cycles take far longer than they used to — Partial heat or poor airflow rather than no heat at all.
- The clothes come out damp and cold — Nothing has been dried; the machine has been tumbling wet laundry in cool air.
- 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 DHP 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 DHP models.
- The heating element, or the igniter and gas valve — The actual heat producer, and a genuinely common failure — though what usually kills one is a blocked or leaking airflow path rather than the part itself. Second.
- A thermal fuse or cut-out has opened — The device did its job. 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 DHP family records a single model code, so there is no variation inside this family to hedge against: what is written here applies to the whole of it. Where this departs from the brand-generic ordering: the cause that moves up to second on these models is this one — the heating element, or the igniter and gas valve — while the brand-generic lead keeps the top.
Check in this order on the DHP models, and why
- Check the programme selected before anything else — First: Air, refresh and delicate settings remove heat deliberately, and this check costs nothing.
- Feel the exhaust at the outside outlet while it runs — Second: 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 — Third: A screen you cannot see light through is blinded, even when it looks clean.
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 DHP 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.
