Oven Control Board Cost Calculator
Estimate Your Oven Control Board Replacement Cost
Quick Takeaways
- Typical UK price for a new control board: £80‑£200 for the part alone.
- Professional labour adds £70‑£150, so total replacement runs £150‑£350.
- DIY can save £70‑£150 but requires basic electrical safety knowledge and a multimeter.
- Older ovens (pre‑2000) may be cheaper to replace entirely than to fix the board.
- Always ask for a written quote that breaks down part, labour, and any diagnostic fees.
What is an Oven Control Board?
In an Electric Oven, the control board (sometimes called the electronic control unit) is the brain that tells the heating elements when to turn on, how hot to get, and when to shut off. It receives inputs from the temperature sensor, timer knobs, and safety switches, then sends power‑modulating signals to the element relays. When the board fails, you’ll see symptoms like: no heat, intermittent heating, error codes on the display, or the oven simply won’t start.
Why Does the oven control board cost Matter?
Understanding the cost helps you decide whether to repair or replace the whole appliance. The price isn’t just the part itself; it includes diagnostics, labour, and any extra components (like fuse holders) that might need swapping. In the UK, repair regulations (British Standards BS EN 60335) require a qualified technician to certify that the work complies with safety rules, which can affect the final bill.
Cost Factors You Need to Know
- Brand and model: Premium brands (Miele, Bosch) use proprietary boards that can cost £150‑£250, while budget brands (Hotpoint, Beko) often have cheaper generic replacements around £80‑£130.
- Age of the oven: Older models may need a hard‑to‑source board, driving up the price or forcing a full‑oven replacement.
- Labour rates: London‑area technicians charge £80‑£100 per hour, whereas regional rates can be as low as £50‑£70.
- Diagnostic fees: Many companies charge £30‑£50 just to test the board; some will waive it if you go ahead with the repair.
- Warranty status: If the oven is still under a manufacturer’s warranty, the part may be free, but you’ll still need a covered service technician.
Typical UK Price Ranges (2025)
Below is a snapshot of what you’re likely to see on an invoice for a standard electric oven repair.
| Brand | Control board part | Labour (average) | Total (incl. diagnosis) |
|---|---|---|---|
| Hotpoint | £85‑£120 | £70‑£100 | £175‑£270 |
| Bosch | £150‑£200 | £80‑£120 | £260‑£350 |
| Miele | £190‑£250 | £90‑£130 | £310‑£410 |
| Beko | £80‑£110 | £60‑£90 | £150‑£240 |
DIY vs. Professional Replacement
Going the DIY route can shave off £70‑£150, but you’ll need:
- A decent Multimeter to test continuity and voltage.
- DIY Safety Gear - insulated gloves, safety glasses, and a non‑conductive screwdriver set.
- Access to the correct replacement board - often ordered from the manufacturer’s parts portal or a reputable UK supplier.
If you’re not comfortable working with mains voltage (240 V in the UK), hiring a certified Service Technician is the safest bet. Professionals also carry liability insurance, which protects you if something goes wrong.
Step‑by‑Step Guide to Replacing the Board (DIY)
- Safety first: Switch off the oven at the wall socket and lock the circuit breaker.
- Remove the back panel (usually a few Philips‑head screws).
- Locate the control board - it’s a rectangular PCB with a metal shield and wired connectors.
- Disconnect the wiring harnesses. Snap‑in connectors usually have a release tab; press it gently.
- Unscrew the mounting brackets and lift the board out.
- Compare the old board with the new one (pin layout, connector types) to ensure a match.
- Secure the new board with the original brackets and reconnect all harnesses.
- Re‑attach the back panel, restore power, and run a quick test (heat‑up a small batch of food). If the oven cycles correctly, you’re done.
If the oven still won’t heat, check the fuse holder (often a ceramic component) and the temperature sensor with your Multimeter. A faulty sensor can mimic a board failure.
How to Get an Accurate Quote from a Technician
- Ask for a written breakdown: part cost, labour hours, and any additional fees.
- Confirm whether the quote includes a Diagnostic Fee and whether it’s waived if you proceed.
- Inquire about warranty on the replacement board - most UK suppliers offer 12‑month coverage.
- Check if the technician follows BS EN 60335 standards; reputable firms will state this on their quote.
When to Replace the Oven Entirely
If the total repair cost exceeds 50‑60 % of the price of a comparable new oven, replacement makes more sense. For a 20‑year‑old Hotpoint model, a £300 board fix might be cheaper than a brand‑new 70‑liter oven at £650‑£800, but consider the long‑term energy efficiency - newer models use lower‑wattage elements and smarter controls.
Tips to Keep Future Repair Costs Low
- Regularly clean the oven vents and fan to prevent overheating of the board.
- Use the self‑clean feature sparingly; high‑heat cycles can stress solder joints.
- Invest in a surge protector for your kitchen circuit - power spikes are a common cause of board failure.
- Schedule a professional check‑up every 3‑4 years, especially for high‑use ovens.
Quick FAQ
How long does a professional oven control board replacement take?
Most technicians complete the job in 1‑2 hours, including diagnosis and testing.
Can I replace the board myself without voiding my warranty?
If the oven is still under the manufacturer’s warranty, any DIY work typically voids it. It’s safer to let an authorised service centre handle the repair.
What are the signs that the control board has failed?
Common symptoms include no heat, the oven displaying error codes, intermittent heating, or the timer knobs not responding.
Is it worth buying a refurbished control board?
Refurbished boards can save £30‑£50, but ensure they come with a 90‑day guarantee and are sourced from a reputable dealer.
Do I need a gas safety check for an electric oven?
No. Gas safety checks apply only to gas‑fed appliances. Electric ovens only require electrical safety inspections.
Next Steps & Troubleshooting
If you’ve identified a faulty board, start by contacting at least three local repair firms for quotes. Compare the written breakdowns, ask about warranty, and verify the technician’s qualifications (look for a Gas Safe‑registered electrician if your oven has mixed gas/electric features). If you decide to DIY, double‑check that the replacement board matches the model number printed on the original PCB.
Should the oven still misbehave after a board swap, re‑test the temperature sensor and the mains inlet for loose connections. A persistent fault usually points to either a damaged wiring harness or a failed heating element, both of which will add to the repair bill.
Keeping a simple log of any error codes and the dates they appear can help the technician pinpoint recurring issues faster, potentially lowering labour costs.
