When your oven won’t heat, displays error codes, or acts up randomly, the culprit is often the oven control board, the digital brain that tells your oven when to turn on, how hot to get, and how long to cook. Also known as the clock timer board or electronic control unit, it’s not a flashy part—but without it, your oven is just a fancy metal box. This isn’t something you fix with a screwdriver and hope. It’s a precision component that fails from age, power surges, or moisture, and replacing it isn’t always cheap—but it’s usually cheaper than buying a whole new oven.
Most oven control board replacements, a direct fix for malfunctioning temperature control, display errors, or unresponsive buttons cost between £150 and £350 in the UK, including parts and labor. The price varies by brand—Bosch, Whirlpool, and Siemens boards run higher because they’re more complex. Cheaper models might be under £100, but labor still adds £70–£120. Compare that to a new oven, which starts at £500 and can hit £2,000. If your oven’s under 10 years old, replacing the board almost always makes sense. If it’s older, you’re balancing repair cost against energy efficiency and future breakdowns.
Some people try to fix it themselves. You can buy the board online for £50–£150, but if you’re not comfortable working with live wiring, you risk frying the whole system—or worse, starting a fire. Even if you’re handy, matching the exact part number matters. A wrong board won’t work, and returns are messy. Most appliance repair technicians, trained specialists who diagnose and fix home appliance electronics carry common boards in their vans and test the old one first to confirm it’s the issue. No guesswork. No wasted time. Just a clear diagnosis and a fix that lasts.
You’ll see posts below that talk about when to call a pro versus fixing it yourself, how electric ovens fail, and why some repairs are smarter than replacements. These aren’t theory pieces—they’re real experiences from people who’ve been there. One guy in Warwick spent £280 to fix his 8-year-old oven instead of buying a new one for £900. Another tried a DIY fix, broke the display, and ended up paying double. The difference? Knowing whether the problem is the board, the heating element, or just a loose wire. That’s what this collection gives you: no marketing fluff, just what works.
Replacing an oven control board in New Zealand costs between $250 and $750, depending on the model and labour. Learn how to tell if it's really the board, whether to DIY or hire a pro, and when to replace the whole oven instead.
