The short answer
Stop using the machine. An Electrolux dryer that trips its breaker, smells of hot insulation or gives any sensation of shock is reporting a fault that has already reached a live conductor, and a dryer adds lint and heat to that combination. Isolate at the breaker, then make the observations below without powering the machine up to reproduce the fault.
Causes, ranked for this Electrolux dryer
- Lint accumulation on hot components inside the cabinet — Why: Lint that has passed a damaged filter or seal settles on the heater and wiring, and it both smells and burns; on a dryer this ranks first because it is the mechanism behind most appliance fires.
- Heating element breaking down to earth — Why: An element failing to earth trips the protection the moment heat is called for, which is why the trip is timed to the heater rather than to the motor.
- Damaged supply cord or an overheating outlet — Why: A dryer is pushed back against its own cord repeatedly, and the resulting damage or a loose outlet connection generates heat at the plug — an electrician job rather than an appliance one.
- Motor winding insulation failing — Why: A motor breaking down trips under mechanical load and often smells before it fails, and it cannot be confirmed without a meter.
- Missing or interrupted earth connection — Why: A compromised earth leaves the chassis at potential rather than clearing the fault, which is what turns an internal defect into a shock at the door.
What to check, in order
- switch the circuit off at the breaker and stop using the machine. — Because: every symptom on this page means a live conductor has already gone where it should not be.
- look at the outlet and plug for heat discolouration, melting or a loose fit. — Because: a supply-side fault is common, dangerous and visible without opening anything.
- note exactly when the trip happens: at start, when the heat comes on, or at random. — Because: the timing points at the motor, the element or the wiring, and it is what the technician needs.
- check whether the vent and lint path have been neglected. — Because: lint on hot components is the mechanism behind most dryer fires and it is the one you can act on.
Checks you can safely do yourself
- Switch the dryer circuit off at the breaker and leave it off; do not run a cycle to reproduce the fault. — Tools: none — Time: a minute
- Unplug the machine where it is plug-connected and inspect the plug and outlet for discolouration, melted plastic or a loose blade. — Tools: a torch — Time: several minutes
- Look along the visible length of the supply cord for crushing, cuts or abrasion where the machine sits against the wall. — Tools: a torch — Time: several minutes
- Write down when the trip or smell occurs relative to the cycle, and whether the machine was heating at the time. — Tools: none — Time: a few minutes
- Check the lint screen, its housing and the exhaust duct for heavy accumulation. Stop here: nothing inside the cabinet should be opened or metered by an owner on this fault. — Tools: a torch and a vent brush — Time: several minutes
Before you open anything
Safety

Do not use a dryer that has given anyone a shock, that trips its protection, or that smells of burning, and never reset a breaker repeatedly to finish a load. Keep the circuit off until it has been assessed. Lint plus heat plus a fault is the combination behind most appliance fires, so this is not a wait-and-see fault.
Where the owner fix ends
The observations above are owner work; the repair is not. Call a technician for any trip, burning smell or shock, because each requires insulation and earth-continuity testing that cannot be done safely without instruments. Call an electrician instead when the outlet, plug or cord shows heat damage, or when other appliances trip the same circuit.
