The short answer
A breaker that trips or a connection that has scorched: on an IKEA oven that is usually one leg of the supply lost, not a shorted element. The next thing to rule out is an element shorting to ground. Most causes below are owner checks needing no tools and no panel off; the last is a service call.
What you are looking at
- It trips only on one mode — Bake trips it and broil does not, or the reverse.
- The panel works and no heat arrives — Partial function with a live display.
- There is discolouration at a connection — Browning or melting at the block or receptacle.
- NEAR MISS -- a burning smell on first use — New ovens burn off manufacturing residue once; it should not recur.
Causes, most likely first on this kind of unit
- One leg of the supply has been lost — An oven circuit carries two legs. Top of the list on a badged full-size platform -- on an IKEA appliance on its mainstream OEM platform, this is the commonest electrical complaint on a full-size oven, and the breaker is where it lives.
- An element is shorting to ground — An element that has split or blistered arcs to the cavity. This rank, because a trip the moment one element is called points at that element rather than the wiring.
- The connection has scorched — Oven circuits carry real current. Placed here: scorching at a terminal is heat where none belongs, whatever else is happening.
- The wiring, terminal block or internal harness — Damaged insulation, a burned harness connector or a failed limit switch needs a meter on a high-current circuit and a wiring diagram. It comes last because it is last because it is the only cause here that is never an owner repair.
Check in this order, and why
- Switch the breaker fully off and on, both poles — An oven circuit is typically thirty amps or more at two hundred forty volts; reset it fully rather than nudging it.
- Note which mode trips it — A trip only on bake, or only on broil, points at that element.
- Only after the breaker and the mode pattern are known — Any scorching, any smell of hot insulation, or any repeated trip is a stop-using-it service call.
What an owner can safely check
- Switch the breaker fully off and on, both poles — Do this once.
About 10 min
- Note exactly which mode trips it — Bake, broil, convection or clean -- the mode names the circuit and the element.
About 15 min
- With the breaker off, look for discolouration at the connection — Check the terminal block cover or the receptacle for browning or melting.
Tools: flashlightAbout 15 min
- STOP HERE -- the next step needs a meter on a two-hundred-forty-volt circuit — Elements, relay boards, terminal blocks and harnesses are technician work.
Before you open anything
Safety
Switch the oven off at its breaker before any panel comes off; an oven circuit is a large-appliance circuit, typically thirty amps or more at two hundred forty volts.
When to call a technician
Doors, racks, seals and expectations are yours; elements, valves, sensors and relay boards are not.

What this page does not cover
This page covers the IKEA oven as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: terminal-block part numbers, element resistance figures, wiring diagrams and the panel-removal order, all of which differ by family.
