What this code means, briefly
Read F2 as this: the electronics have overheated and the corresponding cooking zone has been switched off. The rest of the appliance is unaffected; let it cool and the zone will come back, but a trip that repeats needs looking at. You can settle whether this is a one-off or a real fault yourself; naming the failed part is not owner work.

| F2 | The electronics have overheated. The corresponding cooking zone has been switched off. |
What you actually observe
- It happens after a long spell at a high setting — Sustained high power is how the electronics reach their limit in ordinary use.
- The zone comes back after a cooling period with nothing else changed — Recovery on cooling is the signature of protection rather than failure.
- NEAR MISS — it shuts off cold, before anything has warmed up — A cold shutdown is not a thermal trip; that is a sensor or a control fault and a different page.
What triggers F2, most likely first
- A long bake below the cooking surface — It goes first among the causes you can act on: the oven and the surface share a housing on this platform, and a long bake underneath adds directly to what the electronics above it have to shed.
- Sustained high-power use, sometimes with a hot appliance below — Running at the top of the range for a long stretch, or cooking above a hot oven, adds directly to what the electronics have to shed.
- A sensor or control reading a temperature that is not there — Last and least likely: before blaming the reading, the heat has to be shown not to be real, because a false trip and a real trip look identical from outside.
What to check first, second, third
- Check what is directly below and around the appliance — A drawer packed full, a hot oven below or a blocked housing vent all explain a trip that nothing inside the appliance explains.
- Vacuum the housing vents and check the clearance — Free, visible from outside, and the commonest fix.
- Let the appliance cool completely and try again — Recovery on cooling confirms a thermal trip and rules out most of the alternatives at no cost.
What an owner can safely do
- Switch the appliance off and let it cool fully — Give it time with the power off before drawing any conclusion. A protection device needs to fall back below its threshold.
About 45 min
- Let it cool, clear the housing vents and the space below, then repeat the same cooking once — If it trips again at the same point, the cooling path is genuinely restricted rather than merely busy.
Tools: vacuumAbout 60 min
- Clear the vents, grilles and the space around the appliance — Remove anything covering an intake or an outlet, and restore the clearance the manual asks for.
Tools: vacuum, soft brushAbout 20 min
- STOP HERE — the cooling fan and the sensor are inside — Both sit behind a panel next to live terminals, which is where an owner check ends.
Safety first
Safety
Unplug the oven or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off. The cavity and the glass stay hot long after the heat is off, so let everything cool first. On a gas model, if you smell gas, leave the building and call the gas utility from outside.
When to call a technician
Call at once if the appliance is hot enough to be uncomfortable to touch, if you smell hot plastic, or if it trips cold.

Scope of this reading
What is written here is generalized to the Bosch oven line rather than to a single family. Deliberately absent: connector positions, wiring colours, part numbers and the service sequences for your particular build, all of which vary across the line and belong in the manual for your model. If a model-specific page for this code has been published it is linked from the index below, and that page outranks this one for your unit.
