The short answer
An AEG DC dryer that is completely dead is usually stopped at the door, at the outlet or at a protective device, and all three are checkable without tools. A dryer needs power, a door the machine registers as closed, and a start circuit that has not been interrupted. A machine that does nothing at all is failing one of those, and they can be separated in a few minutes from the front. The table below lists two models for this family, and they are close enough that the fault behaves the same way across all of them; what differs between them is parts rather than diagnosis.
What happens when you press start
- Nothing at all when start is pressed — A power question before it is an appliance question.
- It has power but start does nothing — The door circuit or the start switch is not completing.
- It hums on start with the drum still — Power is reaching the motor; either the belt has gone or the motor is jammed.
- It runs only while start is held in — A classic start-circuit signature, and a useful one because it narrows the fault to a switch.
- NEAR MISS — it starts and turns but gives no heat — That is a heating fault and the heating page for this family is the right one.
Causes, most likely first on the DC family
- Power at the outlet, the cord and the protective devices — It leads because a dryer sits on a heavy circuit of its own, so nothing else in the room tells you when that circuit has opened, and an owner can easily assume the machine has failed when the circuit has. The two models of the DC family share this construction, so what ranks first on one of them ranks first on all of them.
- The door not registering as closed — The machine will not run with the door open by design, so a switch that has worn or a door that no longer closes firmly reads to the control exactly like an open door.
- A thermal fuse that has operated — On many machines the thermal fuse sits in the motor circuit as well as the heater circuit, so an overheating event caused by a blocked duct leaves the machine completely dead rather than merely cold.
- A broken drive belt — A broken belt gives the distinctive hum with a drum that spins freely by hand, and it is the one cause here that can be confirmed without any electrical work at all.
Check in this order on these models, and why
- Check the protective devices for the dryer circuit, then look at the plug and outlet for heat damage — First, and it costs nothing.
- Close the door firmly and listen for the switch, then try again — Second, because it is the most common condition left unmet on a machine with power.
- Clear the lint filter and the duct run before assuming anything has failed — Third, and it is the check that connects a dead dryer to an airflow problem.

Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired exactly as it is: it cuts the heater and the motor when the door opens, and that is what keeps a running drum away from your hands. Never run a dryer with the exhaust disconnected indoors. If the machine is a gas model and you smell gas, do not operate any switch — leave the building and call the gas utility from outside.
The line between an owner check and a service call
Call a technician once power, the door, the duct and the belt are proven and it is still dead, because the next step is a meter inside the cabinet with the machine isolated. Call without waiting if the protective device operates the moment it is switched on, if the plug or outlet shows heat damage, or if anyone has felt a tingle from the cabinet.
