When your oven won’t heat, won’t turn on, or shows weird error codes, the oven control board, the main electronic brain that manages temperature, timing, and power to your oven’s components. Also known as oven control unit, it’s not something you can just swap out like a light bulb. This part controls everything—from the bake element to the display—and when it fails, your oven stops working, even if every other piece is fine.
Fixing it isn’t always about the part itself. The oven control board costs between £80 and £250 depending on your oven brand and model. But labor adds another £60 to £120, and if the technician finds other damaged parts—like a faulty temperature sensor or a blown fuse—it’ll add up fast. That’s why many people assume the control board is broken when it’s actually a simpler, cheaper fix. A bad oven temperature sensor can mimic control board failure, and replacing it costs under £30. Same with a tripped thermal fuse or a loose wire connection. That’s why it’s smart to get a diagnosis before you agree to a full board replacement.
Age matters too. If your oven is over 10 years old, replacing the control board might not be worth it. Parts for older models are harder to find, and even if you get it working, another component could fail next month. Newer ovens with smart features are more complex, so repair costs go up. But if your oven’s only 5 years old and you like how it cooks, fixing the control board makes sense. Just make sure the technician tests the whole system—not just swaps the board and leaves.
Some DIYers try to replace the control board themselves. It’s possible if you’re comfortable with wiring and have a multimeter. But one wrong connection can fry the new board or damage the oven’s heating elements. And if you mess it up, you’ll pay more to have it fixed later. Most professionals won’t warranty their work if a customer-installed part caused more damage.
What you’ll find in the posts below are real-world fixes from people who’ve been there. Some saved money by testing their own sensors. Others learned the hard way that a £200 control board replacement wasn’t needed. There’s a post on how to tell if your oven element is bad, another on whether a 20-year-old oven is worth repairing, and one that breaks down why an electrician isn’t always the right person to call. You’ll see exactly what questions to ask, what tools to use, and when to walk away from a repair that’s not worth the cost.
