The short answer
On Fotile a trip, an arc or a burning smell is most often an element arcing to the cavity. Ranked that way because the control runs the elements through relays and reads a sensor, so the electronics sit in the path of almost every fault on this machine.
What you observe
- It started tripping after a spill or a self-clean — Moisture bridging a connection, which can dry out.
- A flash and a bang, then an immediate trip — An element arcing to the cavity, which is usually visible once the oven is cold.
- NEAR MISS: it does not trip, it just will not get hot — That is a heating failure rather than an electrical-safety one, and it has its own page.
Causes, most likely first on Fotile
- An element has failed to earth and is arcing — First on a fitted machine, which is only ever as good as its installation. A bright flash, a bang and an immediate trip, usually as the element is switched on. The element has cracked and is shorting to the cavity, and it often leaves a visible scar or a blown section you can see with the oven cold.
- The terminal block or the supply connection has overheated — Second: on a fitted machine this is the next thing genuinely yours to check. A brown or blackened mark at the outlet, a warm cable, or a smell of hot plastic near the connection rather than inside the cavity. This is the most serious item here and it is an electrician job, not an appliance one.
- Moisture or spilled food has bridged a connection — Third. A boil-over, an over-enthusiastic clean or steam from a self-clean can leave a trip that clears once everything dries.
- A relay, the wiring harness or the control board has failed — Last, and it is the reason the order above matters. It trips on its own circuit, when dry, with sound elements and a clean connection.
Check in this order, and why
- With the breaker off and the oven cold, look along each element for a scar, a blister or a break — A visible break with a trip on switch-on is the answer, and it needs no tool at all.
- Look at the outlet or the connection point for discolouration, and feel whether the cable is warm — Heat at the connection rather than in the cavity moves this from an appliance fault to a wiring one.
- Ask whether the trip started after a spill, a clean or a self-clean cycle — A trip that began right after water got somewhere is worth drying out before anything is replaced.
What an owner can safely check
- Switch the breaker off, let the oven cool, and inspect each visible element — Stop there.
Tools: torchAbout 20 min
- Switch off at the breaker and look for discolouration at the outlet or connection — Do not reconnect it.
Tools: torchAbout 15 min
- Leave the oven off, cold, dry and open for a day, then retest once — If it trips again once dry, stop and call.
Tools: towelsAbout 30 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the oven off at its breaker and leave it off until the cause is known. Never reset a breaker a second time once it has tripped twice on the same appliance: the breaker is doing its job and repeated resets are how fires start. Never open the back of an oven, and if you smell gas at a gas oven, do not switch anything on or off, leave the building and call the gas utility or the emergency services from outside.
When to call a technician
Call an electrician, not an appliance technician, if the outlet or connection is discoloured, the cable is warm, or you smell hot plastic at the connection. Call an appliance technician when the oven trips its own dedicated circuit while dry, with sound elements. In every case leave the breaker off until someone has looked at it.

What this page does not cover
This page covers the brand and the oven class, not one family or model line. Where a family-specific or model-specific page exists for your unit, that page is the more specific answer and it takes precedence over this one. Not here: part numbers, wiring colours and component locations, which differ by family.
