The short answer
Every symptom on this page starts the same way: switch the appliance off at its breaker and leave it off. On a compact cabinet the ranking below separates causes that belong to the installation from causes inside the appliance, and an oven runs on a large-appliance circuit, so the currents involved are not the ones behind a lamp.
What you observe
- A flash or arc from an element inside the cavity — An element failing, which often trips the breaker at the same moment.
- A burning or hot-plastic smell with nothing visible — Stop immediately.
- NEAR MISS: a smell of burning during the first few uses of a new appliance — Manufacturing residue burning off is expected and fades.
Causes, most likely first on this appliance
- An element failing to earth — An element that has blistered or split arcs to the cavity and trips the breaker instantly. Ranked first on Danby: a compact oven has a thin cavity, a small door and electronics sitting close to the heat, so the seal and the heat path dominate everything behind them, and this line spans bar cabinets to apartment units, all of them designed to go where a full-size appliance would not.
- The circuit rather than the appliance — A breaker at the end of its life, a shared circuit, or a connection at the panel. Ranked second: it is in the middle of the list because it is cheap to rule out and expensive to assume.
- A heating connection at the appliance terminal block — A large-appliance connection that has loosened heats, discolours and eventually burns. Ranked third: it ranks below the causes above because it costs more effort, not because it is rare.
- A failed board or relay — A relay welded closed or a board that has failed leaves the oven heating when it should not, or tripping on start. Ranked last: it is last because on an appliance this size the major components outlive everything around them, and replacing one often costs more than the appliance is worth.
Check in this order, and why
- Note whether the trip is instant and comes with a flash — An instant trip with a visible arc is close to conclusive, and it names the part without any tools.
- Note whether other appliances on the same circuit misbehave — A pattern across several appliances points at the circuit, and that is an electrician rather than an appliance technician.
- Stop at the panel — This is diagnosed by someone qualified with the circuit isolated, and it is never an owner check.
What an owner can safely check
- Switch off at the breaker and look at each element for blistering or a split — Do this with the appliance cold and isolated.
Tools: torchAbout 20 min
- Remove any foil and clean heavy spill from a cold, isolated cavity — Take out any foil lining, clean carbonised spill away from the elements and never line the cavity floor.
Tools: soft cloth, non-abrasive cleanerAbout 30 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the appliance off at its breaker the moment you smell burning, see scorching or see an arc, and leave it off. Do not reset a breaker repeatedly: a breaker that trips again is doing its job and resetting it is how a fault becomes a fire. Do not remove the rear panel or open the terminal block. On a gas range with an electric oven, if you smell gas at any point: do not switch anything on or off, leave the building, and call the gas utility or your emergency services number from outside. Do not look for the leak yourself.
When to call a technician
Call as soon as the symptom is a burning smell, scorching at any connection, repeated tripping, or an oven that heats when it was not asked to. Those have no owner side at all.

What this page does not cover
This page covers Danby as a family, not one model line. Where a page exists for the line named on your plate it is linked below and it is the more precise answer. Not here: anything behind the rear panel or inside the terminal block, including connection identification and testing, which is deliberately out of scope.
