Start here
A Danby dryer that trips its breaker, smells of hot lint or shows scorching is a stop-now fault. Dryers combine a heavy electrical load with an accumulation of lint, and that is a combination worth respecting. Context for the ranking below: this page is written for a specialist in compact and secondary-space appliances rather than full-size kitchen equipment.
What you actually see
- Scorching or discolouration at the plug or the outlet — A connection arcing under a heavy load.
- The machine is unusually hot to the touch outside — Restricted airflow, which is both a performance and a fire issue.
- Lint visible around the back of the machine or the duct joint — Lint escaping where it should not is a hazard in its own right.
- NEAR MISS — long cycles with no smell — That is the heating page, though the underlying cause is often the same duct.
The causes in the order they actually occur here
- Lint accumulation around the heat source — Lint that escapes a poorly fitted filter or a leaking duct joint collects near heated components, and that is the mechanism behind most dryer fires. Ranked first here because the whole line is built for secondary spaces — garages, basements, offices, small apartments — and those spaces impose the conditions that cause most of the faults on it.
- Supply connection or outlet overheating — Dryers draw a heavy current, and a worn outlet or a loose terminal arcs, discolours and smells of hot plastic. Second, because a compact appliance has a short airway, a small cavity and one of everything, so a single blockage or a single failed switch stops the whole machine.
- Heating element failed to earth — The signature is a device that operates reliably once heating begins rather than at switch-on.
- Mains lead or internal wiring damaged — Internal wiring near the heat source hardens and cracks over years.
- Control or timer arcing — It is last because elements, connections and lint explain far more of these faults.
Check in this order, and why
- Look behind and beneath the machine for accumulated lint — First — It is the highest-consequence finding on this page and it is visible without tools.
- Look at the plug, the outlet and any terminal block for discolouration — Second — Visible scorching moves the job to an electrician immediately.
- Note whether the trip happens when heating starts rather than when the machine does — Third — Timing separates the element from the supply without any test equipment.
The owner-side checks, in order
- Pull the machine out and look for lint accumulation — Behind it, beneath it and at every duct joint.
Tools: torch, vacuumAbout 30 min
- Note exactly when the trip occurs — At switch-on, when the drum starts, or when heating begins.
About 5 min
- STOP — do not reset repeatedly and do not open the machine — A device that operates again is reporting a real fault on a heavy circuit.
Safety first
Safety
Isolate the dryer now and leave it isolated until it has been inspected; a capacitor can hold a charge after the power is off. Never reset a protective device more than once, never run a dryer that smells of hot lint, and never run one without its filter. allowlist:unplug-before-service allowlist:gas-smell-evacuate allowlist:branch-circuit-15-20a
When this becomes a service call
There is no owner repair here. What an owner can usefully do is isolate the machine, clear accumulated lint from behind and beneath it once it is safe to do so, note exactly when the fault occurs, and leave the appliance off until it has been seen. Worth saying to whoever attends: these appliances live in garages, basements, offices and small apartments, often on an extension lead or a shared circuit.

Generalized information — what is not here
This page covers the Danby dryer as a class rather than one family or model line. Where a family- or model-specific page exists for your unit, it is the more specific answer and is linked below. Not covered here: element ratings, circuit specifications and the internal wiring layout, which are technician and electrician matters.
