The short answer
No heat on the AED family is one of the few faults where fixing the failed part without finding the cause guarantees a repeat. This family spans a pair of model numbers rather than a range. A thermal cut-out opens because air stopped moving, so the duct is checked in the same visit as the part.
The observations that separate this fault from its neighbours
- Some warmth but nothing like normal — Partial heat, which on a machine fed by two supply legs can mean one of them has been lost.
- On a gas model, no sound of ignition at all — The igniter or the gas supply rather than anything electrical in the drum circuit.
- It heated until recently and then stopped completely — A sudden loss points at a thermal device opening rather than at gradual wear.
- Cycles got longer before the heat stopped altogether — The same story earlier on. Long cycles are the warning that precedes this fault.
- NEAR MISS — it heats but the clothes are still damp — That is airflow, covered on the cycle page for this family.
Causes, most likely first on the AED line
- The element, or the igniter and gas valve — Ranked first because history is diagnostic: no run of long cycles before the failure means nothing was restricting the airflow, which is what would have opened a cut-out.
- A device that has opened — Second, and always checked alongside the first — the two are indistinguishable from outside the machine and are tested in the same operation.
- Supply and breaker — Third. Free to check, external, and it explains the version of this fault where nothing inside the machine is wrong at all.
- Filter, duct and vent — Fourth. Part of every dryer repair regardless of the fault, because it is the condition that determines how long the fix lasts.
- Thermostats and control — Last, and the one that should never be replaced speculatively.
What to check first, and why that order
- Ask what happened before the heat stopped — Weeks of very hot running or long cycles point at a protective device; a clean sudden stop points at the source.
- Check the supply at the breaker — Placed early because it is free and it is a complete explanation on some installations.
- Feel the exhaust outlet during a cycle — Weak flow says restriction, which changes what any internal finding means.
- Clear the whole airflow path — Filter, housing, duct run and the flap outside — all four, not the easiest one.
- Hand over for internal testing — Cut-outs, elements, igniters and valves are meter work behind panels, and on a gas model they are licensed work.
Before you open anything
Safety
Power off at the breaker or the plug before the back or the front panel comes off, and treat lint as a fire load rather than as dirt. On a gas model, shut the gas off at the appliance valve before the machine is moved, and if you smell gas, leave the building and call the gas utility from outside rather than investigating. The exhaust duct and the heat source stay hot well after a cycle ends.

Where owner work stops
Call once the supply has been checked and the whole airflow path is clear and the machine still tumbles cold. On the AED family the duct, the filter and the breaker are owner work; elements, igniters, gas valves, thermal fuses and cut-outs are not, and on a gas model none of the heat circuit is owner work at any point. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility from outside.
