Oven
F2
The F2 error code on a Miele oven indicates a temperature sensor (NTC sensor) fault — specifically that the oven is detecting an abnormal or implausible temperature reading. It’s a moderately serious fault that will prevent your oven from heating safely until it’s resolved.
What does this error mean?
Miele ovens use an NTC (Negative Temperature Coefficient) sensor to continuously monitor the internal cavity temperature. An F2 code means the oven’s control board has received a reading from that sensor that is either out of range, erratic, or missing entirely. In plain terms: the oven doesn’t trust what it’s being told about its own temperature, so it shuts down the heating circuit as a precaution.

🔍 Likely causes
🛠️ Step-by-step fix
1. Hard reset the oven: switch it off at the wall socket (or isolate at the fuse board), wait 10 minutes, then power it back on. A transient glitch can occasionally trigger F2 and a full power reset clears it.
2. Check for obvious wiring damage: pull the oven away from the wall (unplug it first), remove the rear panel if accessible, and visually inspect the wiring loom leading to the temperature sensor for any burnt, pinched, or disconnected wires. Do not open any sealed electrical enclosures.
3. Inspect and reseat the sensor connector: locate the NTC sensor plug (usually a small 2-pin connector at the back of the oven cavity or behind the rear panel) and firmly disconnect and reconnect it to clear any corrosion or loose contact.
4. Test the NTC sensor with a multimeter: a healthy Miele NTC sensor typically reads around 990–1,010 ohms at room temperature (20°C). A reading of zero, infinity, or wildly outside this range confirms a failed sensor.
5. Replace the NTC temperature sensor: Miele NTC sensors are available from Miele’s own spare parts service or UK appliance parts suppliers (e.g. 4WheeledParts, eSpares). Ensure you match the exact part number from your oven’s model plate. This is a straightforward plug-and-replace job requiring only a Torx screwdriver.
6. If the error persists after sensor replacement, stop DIY work — the control board (PCB) is likely faulty and requires a qualified technician to diagnose and replace safely.
📞 When to call a professional
If the error code returns after a hard reset and you’re not comfortable using a multimeter or accessing internal components, call a Miele-approved or reputable local appliance engineer. Tell them: ‘My Miele oven is showing an F2 error code — I suspect an NTC temperature sensor fault.’ If you’ve already replaced the sensor and the fault persists, a PCB replacement is almost certainly needed and is not a DIY job.
⚖️ Repair or replace?
A professional repair for an F2 fault (sensor replacement) typically costs £80–£150 including parts and labour in the UK; a PCB replacement will run £150–£300+. Miele ovens are built to last 20+ years, so if your oven is under 12–15 years old and otherwise in good condition, repair is nearly always worth it. If it’s older than 15 years and needing a PCB, weigh the repair cost against a new mid-range oven (£600–£1,200) carefully.
