Cooker
F07
The F07 error code on a Smeg cooker indicates a fault with the oven’s temperature sensor (NTC probe), meaning the appliance cannot accurately read or regulate its internal temperature. It’s a moderately serious fault — the oven will typically stop heating or refuse to start until it’s resolved.
What does this error mean?
F07 signals that the oven control board has detected an abnormal reading from the temperature sensor, also called the NTC (Negative Temperature Coefficient) probe. This probe constantly monitors the oven cavity temperature and feeds data back to the control board. When the signal falls outside the expected range — too high, too low, or absent — the board throws F07 and shuts down heating as a safety precaution.

🔍 Likely causes
🛠️ Step-by-step fix
Power cycle the oven: switch it off at the wall socket or isolate it at the fuse board, wait 5 minutes, then power it back on. A temporary glitch can trigger F07, and a hard reset often clears it.
Check the error code in your Smeg manual: confirm F07 specifically relates to the temperature sensor on your exact model (Smeg’s fault code numbering can vary slightly between series). Download your model’s manual free from smeg.com if needed.
Inspect the NTC probe for visible damage: open the oven door and locate the probe — it’s a small metal spike, usually mounted on the back wall or side of the oven cavity. Look for obvious burning, corrosion, or a snapped tip. Do not touch it while the oven is hot.
Check the wiring connector: with the oven fully isolated from the mains, carefully pull the oven away from the housing if freestanding, and locate the connector linking the probe cable to the main harness. Unplug it, check for corrosion or bent pins, and firmly reseat it. This alone fixes a significant number of F07 faults.
Replace the NTC temperature sensor: if the probe is visibly damaged or a multimeter test shows resistance outside the expected range (typically 1,000–50,000 ohms depending on temperature), order a genuine Smeg replacement probe for your model number. Replacement is straightforward — usually one or two screws and a single connector. Parts cost £15–£40 online.
If the fault persists after a new probe, stop DIY work — the control board is likely faulty and requires a qualified appliance engineer to diagnose and replace safely.
📞 When to call a professional
Call a qualified appliance engineer if the F07 error returns after you’ve replaced the NTC probe, or if you’re uncomfortable working inside the oven’s wiring. Tell the engineer: ‘My Smeg oven is showing an F07 fault — I believe it’s the NTC temperature sensor or control board.’ This helps them bring the right parts and speeds up the job. Note your full model number (found on the rating plate inside the door frame) before calling.
⚖️ Repair or replace?
A professional repair for an F07 fault — whether a probe replacement or a new control board — typically costs £80–£200 including labour in the UK. If your Smeg cooker is under 8 years old and was a mid-to-high-end model (£600+), repair is almost always worth it. If it’s over 10 years old or the control board has failed on a budget model, replacement is likely more cost-effective given that a new comparable Smeg cooker starts around £500–£800.
