What F25 actually means
The oven has found that its own electronics are running too hot and has shut the heating down to protect itself.
There is a temperature sensor (an NTC) fitted on the oven's power board, behind the control panel. When it reads a temperature above the safe limit, the control cuts the heating and shows this code rather than carry on and cook its own circuitry. In practice it usually appears part-way through a bake or a long high-temperature cook, once heat has had time to build up around the controls.
What usually causes it
- The cooling fan that draws air across the controls has stopped running
- Airflow around the control panel or vents blocked by trapped grease or debris
- Oven built into a tight housing with the vent path obstructed
- The temperature sensor on the power board reading falsely high
- A failed power board
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the oven off at the wall for a minute, then back on — if the board had simply overheated it may clear once cool
- Let the oven cool completely with the door open before trying again
- Listen after switching on: you should hear the cooling fan running. If it is silent, that is your likely culprit and needs an engineer
- Check the vent slots above or below the door are not blocked by foil, trays or baked-on grease
- If the oven is under a hob or in a fitted housing, make sure nothing is stuffed around it restricting airflow
When to call someone
This one usually needs an engineer once you have tried the checks above. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
