The short answer
A dryer that trips its breaker, smells hot or gives a tingle is reporting an insulation fault in a machine that is designed to get hot. The correct response is to take it out of service, not to work through it cycle by cycle. On a Avanti dryer the order below is what makes this page worth reading — the causes are ranked for this kind of machine, not listed alphabetically.
What this looks like from the front
- The breaker trips when the heat comes on — Timing is the clue: a trip at the heat step points at the element circuit rather than the motor.
- A hot or scorched plastic smell from the back of the machine — Terminal blocks and heater connections are at the back, and they run hot by design. Overheating there is a connection fault.
- A tingle from the cabinet or the door frame — Take it out of service now. That is current on the chassis, which means the earth path has been compromised.
- Scorching at the plug, the cord or the outlet — A high-current appliance on a loose connection generates heat every minute it runs.
- NEAR MISS — the machine is simply dead with no smell — A no-power complaint with no heat, smell or trip is a supply or start question, not a safety one.
Ranked causes on this platform
- Heating element shorting to the drum or the cabinet — First, because the element is the highest-current part in the machine and it sags as it ages. A sagged coil touching the housing trips the breaker the instant the heat is commanded, which is why the timing is so consistent.
- Loose or corroded terminal connections — Second. High current through a loose joint makes heat, heat makes oxide, oxide makes more resistance — it is a self-worsening fault and it produces the scorched smell long before anything trips.
- Lint on live components inside the cabinet — Third, and the reason this category is treated seriously: lint is conductive when damp and flammable when dry, and it collects exactly where the heater terminals are.
- Damaged supply cord or an unsuitable outlet — Fourth. Crushed cords behind the machine and adaptors on a heating appliance belong here, and both are visible without tools.
What to check first, second, third
- Note whether the trip follows the heat or the motor — Run an air-only cycle if the machine offers one. Tumbling without tripping isolates the fault to the heating circuit.
- Check the plug and outlet face for heat damage — Unplugged, with a light. Browning or a loose pin is a finding you can act on immediately.
- Smell around the back panel after a cycle — Connection overheating is smelt long before it is seen, and the back of the machine is where it happens.
What you can do yourself
- Stop using the machine and disconnect it — This is step one. A dryer with an electrical fault and a cabinet full of lint is not a machine to keep testing.
About 5 min
- Inspect the cord and the outlet — Look for crushing behind the cabinet, discolouration at the pins and any looseness in the socket.
Tools: flashlightAbout 15 min
- Clear all reachable lint from the screen housing and duct — Reducing the fuel load is worthwhile regardless of the electrical diagnosis, and it costs nothing.
Tools: vacuumAbout 30 min
- Check whether other appliances trip the same circuit — It separates a house fault from an appliance fault before anyone is called.
About 10 min
- STOP — do not open the cabinet on an electrical fault — The heater terminals, the motor and the cut-outs are all in there, and none of them are owner-serviceable.
Safety first
Safety
Power off at the breaker before any panel comes away, and treat the heater terminals as live until proven otherwise. A dryer fire almost always starts in accumulated lint, so the lint path is part of the safety job, not part of the cleaning job. Do not run the machine with the door switch defeated.
The line between a fix and a call
Call straight away and leave the machine disconnected. Do not reset the breaker to finish a load: on a dryer the protective device is standing between a shorted element and a cabinet full of lint, and every reset re-energises a known fault. Mention whether the trip follows the heat or the tumble, because it decides which circuit is opened first and can save a diagnostic visit.

Generalized information
This page is generalized across the Avanti dryer line: it covers the appliance class rather than one family or one model line. Where a family- or model-specific page exists for your unit it is the better answer and it is linked from this page — check the model label before you rely on anything here. What is deliberately not on this page: wiring colours, board part numbers, torque figures and teardown order, all of which differ by family and belong on the page for that family.
