The short answer first
On the AGD dryer this symptom is usually the thermal fuse, because on this platform it sits in a circuit that stops everything rather than just the heat. The AGD family covers one model number and nothing else, which means there is no revision to identify before ordering a part.
What an owner actually sees
- A hum for a second or two and then silence — The motor is trying and failing, which is a motor or a jam rather than a switch.
- It starts only if the door is pushed hard — The door switch is marginal, and that is the whole diagnosis.
- The start button has needed harder presses for weeks — A control wearing out rather than failing suddenly.
- The drum spins with no resistance at all by hand — The belt has gone, and on machines with a belt switch that also explains the silence.
- NEAR MISS — it starts and runs but never heats — A machine that tumbles without heat is a heating fault, and that is a different page with a different list.
Causes, most likely first on the AGD family
- Thermal fuse open, stopping the whole machine — Top of the list here. When the fuse is in the motor circuit, an overheat leaves a completely dead dryer instead of a cold one, which is far more alarming and no more serious.
- Supply, breaker or receptacle — Second here. It is checked early because it costs nothing and because it explains a completely silent dryer better than anything inside it.
- Drive motor or its start winding — Third on this platform. A failed start winding leaves a motor that buzzes for a few seconds and then falls silent as its protection opens.
- Belt switch tripped by a broken belt — Fourth: possible, but not where to start. Turning the drum by hand tells you immediately, and it is the last free check available.
- Body: A brand-generic article on this symptom starts with the door switch. Here the thermal fuse moves ahead of it, because with one model number in scope there is no brand-wide averaging left in the ranking.
The order to work in
- Note whether the machine went dead straight after a cycle that ran hot — A dryer that died at the end of a long, hot, slow-drying cycle has almost certainly blown its fuse.
- Switch the breaker fully off and back on, and check the plug is fully home — A full reset rather than a nudge is what clears a half-tripped double breaker.
- Listen for a hum or buzz when start is pressed — Hum without rotation is a motor or a jam; complete silence is the circuit ahead of it.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel or turning the drum by hand — a capacitor can hold a charge after the power is off. Never bypass or tape the door switch to make the machine run: it is the device that stops the drum when someone reaches in. A standard household branch circuit is fifteen or twenty amps at one hundred and twenty volts, while an electric dryer circuit is typically thirty amps or more at two hundred and forty.

Where the owner fix stops
Call rather than retry repeatedly if the motor hums and stops: repeated attempts against a jam overheat the winding. Call rather than replace a thermal fuse a second time — the airflow problem behind it has not been found yet.
