The short answer
A connection that has scorched: on an IKEA oven that is usually one leg of the supply lost. 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.
