Oven
F2
The F2 error code on a Beko oven points to a temperature sensor fault — specifically, the oven is detecting an abnormal reading from its internal thermostat or NTC (temperature) sensor, which means it can’t safely regulate heat. It’s one of the more common Beko oven faults and, while it will stop your oven from working, it’s not always an expensive fix. In this guide, you’ll learn exactly what causes the F2 code, which steps you can safely try yourself at home, and when it’s time to call in a professional appliance engineer.
What does this error mean?
The F2 error code on a Beko oven indicates a fault with the oven’s temperature sensing circuit. Your oven relies on a small component called an NTC sensor (also known as a thermistor or oven temperature probe) to constantly monitor the internal temperature of the cavity. This sensor feeds live temperature data back to the oven’s control board so it can adjust the heating elements and maintain the temperature you’ve set. When the control board receives a reading that is either out of the expected range — too high, too low, or no signal at all — it flags an F2 fault and shuts the oven down as a safety precaution. In plain terms: your oven doesn’t know how hot it is inside, so it refuses to run rather than risk overheating or undercooking your food. This is a sensible safety measure, but it does mean the oven is effectively locked out until the underlying issue is resolved.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Power reset the oven: Before anything else, switch the oven off at the wall socket or turn it off at your fuse box/consumer unit. Leave it completely without power for at least 5 minutes, then switch it back on. This clears any temporary electronic glitches. If the F2 code disappears and the oven runs normally, monitor it closely — if the code returns, move on to the next steps.
Step 2 — Check your Beko oven’s user manual: Locate your model number (usually on a sticker inside the oven door frame) and check the manual or the Beko UK support website (beko.com/gb-en) to confirm that F2 specifically relates to the temperature sensor on your model. Some Beko ranges assign codes slightly differently, so it’s worth a 2-minute check.
Step 3 — Inspect the oven cavity for obvious damage: With the oven completely cold and unplugged, open the oven door and look inside the cavity. The NTC temperature sensor is usually a small metal probe, roughly 3–5cm long, mounted on the back wall or side wall of the oven interior — it looks like a short metal pin or bullet. Check whether it appears physically damaged, discoloured, or has visibly burnt wiring near the attachment point. Do not touch internal wiring at this stage.
Step 4 — Check the sensor is seated correctly: Still with the oven unplugged and cold, look closely at the NTC sensor probe. It is typically secured by one or two small screws (usually a T20 Torx or a small Phillips head). Gently check it hasn’t worked loose from its mounting. A loose sensor can give a false reading. You can re-seat and tighten it using a small screwdriver — no specialist knowledge is required for this step alone.
Step 5 — Test the NTC sensor’s resistance with a multimeter (optional DIY step): If you own a multimeter and are comfortable using one, you can test the NTC sensor without opening any sealed electrical panels. Unplug the oven, unscrew the sensor from the oven wall, and carefully pull it out slightly to access its connector. Disconnect the sensor connector and set your multimeter to the resistance (Ω) setting. At room temperature (around 20°C), a healthy Beko NTC sensor typically reads approximately 4,500–5,500 ohms. A reading of zero, infinite, or wildly outside this range confirms the sensor has failed. You will need a multimeter (available from £10–£20 at B&Q or Amazon).
Step 6 — Replace the NTC temperature sensor (DIY-safe): If your multimeter test confirms a faulty sensor, or if you’d rather simply replace it as the most likely culprit, this is a straightforward DIY repair. Order a genuine Beko NTC oven sensor for your specific model — search your model number on a UK spares site such as eSpares, 4ourhouse, or BuySpares. Genuine Beko sensors typically cost £10–£25. With the oven unplugged, unscrew the old sensor (usually 1–2 screws), unplug the wiring connector, plug in the new sensor, screw it back in place, restore power, and test. This repair requires only a screwdriver and takes around 15–20 minutes.
Step 7 — Inspect accessible wiring for visible damage: If replacing the sensor doesn’t clear the F2 code, visually inspect the wiring harness that runs from the sensor towards the back of the oven. Look for any burnt, frayed, or melted insulation on wires you can see without removing any panels. If you spot obvious wire damage near the sensor connection point, this may be repairable with a proper appliance-rated connector and appropriate wire — but if you are not confident working with appliance wiring, stop here and call a professional.
Step 8 — Do NOT attempt to access or replace the control board yourself: If the sensor, its connector, and the visible wiring all appear fine and the F2 code persists, the fault likely lies with the main PCB (control board). Replacing a PCB involves accessing internal electrical components of the appliance. Unless you are a qualified electrician or appliance engineer, this is not a safe DIY task. Stop here and book a professional repair — see the section below.
📞 When to call a professional
You should call a professional appliance engineer if: the F2 code returns immediately after a power reset; replacing the NTC sensor yourself does not resolve the fault; you can see burnt or damaged wiring inside the appliance but are not confident repairing it safely; or if your oven is a gas-electric range (electric oven with gas hob), in which case any internal engineer work should be carried out by someone who is both appliance-qualified and Gas Safe registered. When you call, tell the engineer: the exact error code (F2), your oven’s full model number (found on the sticker inside the door frame), what you have already tried (reset, sensor replacement), and whether the fault is constant or intermittent. This will save time and may reduce your call-out charge. To find a reputable engineer, look for members of the Domestic Appliance Service Association (DASA) or ask for a local engineer who specifically works on Beko appliances. Always get a written quote before authorising any repair.
⚖️ Repair or replace?
For most UK homeowners, a Beko oven showing F2 is worth repairing if the appliance is under 8 years old and the fault is confirmed as a sensor or wiring issue. A sensor replacement is inexpensive (£10–£25 for the part) and straightforward. If the control board (PCB) has failed, professional repair typically costs £150–£250 including parts and labour — at that point, age matters. If your Beko oven is more than 8–10 years old and needs a new PCB, the maths often favour replacing the oven rather than repairing it. A decent mid-range Beko built-in electric oven (such as the BIE22301X or similar) retails for £250–£400 in the UK, and you’d benefit from a new warranty and improved energy efficiency. If the oven is 5 years old or less and has otherwise been reliable, a professional repair almost always makes financial sense. Beko UK spare parts availability is generally good, and genuine sensors and PCBs are readily stocked by major UK parts suppliers, so you’re unlikely to face long lead times.
