The short answer for D models
On an Avanti D microwave the electrical symptoms worth separating are the ones that appear at rest and the ones that appear under load. A breaker that trips the moment the oven is plugged in is a different fault from one that trips only when it runs, and a technician will want to know which you have.
What the owner sees
- The breaker trips the moment it is plugged in — A fault present at rest, which is a different and usually simpler failure.
- Scorch marks on the plug or the flex — Almost always the connection rather than the appliance, and it is urgent.
- The plug or the socket is hot to the touch — A connection fault outside the oven, and it is a fire risk in its own right.
- A hot or acrid smell during or after use — Overheating insulation or a component, and a reason to stop immediately.
- NEAR MISS — the oven simply will not start — That is a start fault and it has its own page and its own list.
Causes on D, most likely first
- High-voltage component shorted — Ranked first for a breaker that trips under load, because that is the only section of the oven that draws heavily enough to do it.
- Earth fault in the appliance — A tingle from the cabinet or an RCD tripping, and the oven should be unplugged and left.
- Control board failure — Last on the list, and it rarely presents as a tripped breaker.
- Cavity paint damaged so the steel arcs — Chips and rust in the cavity produce sparking that looks alarming and has a simple cause.
The order that saves the most time
- Where to begin — Work down this list rather than starting where the fault seems loudest.
- Unplug the oven before doing anything else — A capacitor inside can hold a charge after the power is off, so the plug comes out first, every time.
- Stop and leave it unplugged once you have a description — Beyond this point every test needs an instrument and training.
- Ask what else is on the same circuit — A standard household branch circuit is fifteen or twenty amps at one hundred and twenty volts, and several appliances can exceed that.
Before you do anything else, unplug it
Safety
Unplug the microwave at the socket before you examine anything, and keep the case closed. The capacitor in the high-voltage section can hold a lethal charge after the power is off. Do not run the oven empty, do not defeat any door interlock, and take the appliance out of service entirely if the door is damaged or the oven runs with the door ajar — the door is what contains the energy.

When to call a technician
Call for anything that is not cleaning. The high-voltage capacitor inside can hold a lethal charge after the oven is unplugged, so there is no owner repair on this appliance beyond the cavity, the turntable and the door seal face.
