Cooker
F02
The F02 error code on a Beko cooker indicates a fault with the oven temperature sensor (NTC probe) — the component responsible for monitoring the heat inside your oven cavity. It’s one of the more common error codes on Beko’s range of electric cookers and built-in ovens, and while it sounds alarming, it’s often a straightforward fix. In this guide, you’ll learn exactly what triggers the F02 code, the most likely causes specific to Beko appliances, what you can safely try yourself, and when it’s time to call in a professional.
What does this error mean?
The F02 code on a Beko electric cooker or oven means the appliance’s control board has detected an abnormal reading from the oven temperature sensor — also known as the NTC (Negative Temperature Coefficient) thermistor. This sensor sits inside the oven cavity (usually mounted on the back wall) and constantly feeds temperature data to the control board, allowing it to regulate heating elements accurately. When the board receives a reading that’s too high, too low, or simply absent — suggesting the sensor is open-circuit, short-circuit, or has failed entirely — it shuts the oven down and displays F02 as a safety measure. In plain terms: your oven can’t verify how hot it is, so it refuses to operate until the issue is resolved. This is a safety feature, not a catastrophic failure, and the oven itself is likely undamaged.

🔍 Likely causes
🛠️ Step-by-step fix
1. POWER OFF AND RESET — Turn the cooker off at the wall socket or isolate it at the fuse spur / consumer unit. Leave it completely without power for 10 minutes. This allows the control board to fully reset. Restore power and check whether F02 has cleared. If the oven works normally, monitor it closely — a one-off glitch can occasionally trigger a false code.
2. CHECK FOR A PATTERN — Before doing anything else, note when F02 appears. Does it show immediately on power-up, or only after the oven has been running for a few minutes? An immediate fault strongly suggests a wiring or sensor failure. A fault that appears mid-cook may indicate an overheating issue or an intermittent connection.
3. INSPECT THE OVEN CAVITY FOR VISIBLE DAMAGE — Open the oven door and look at the rear wall. The NTC temperature sensor is a small probe (usually a slim metal pin or bulb, roughly 3–6cm long) mounted to the back wall with one or two screws, with a thin wire running to it. Look for obvious signs of damage: scorched insulation, a probe that has physically broken, or a wire that has melted or detached. No tools needed at this stage — visual inspection only.
4. CHECK THE SENSOR CONNECTOR (SAFE DIY — APPLIANCE UNPLUGGED ONLY) — With the oven fully disconnected from the mains (not just switched off — unplugged or isolated), you can gently pull the oven away from the wall slightly to access the back if it is a freestanding cooker. The NTC sensor wire runs through the oven cavity back wall to a connector inside or behind the appliance. Carefully press the connector firmly back into place if it appears loose. Do not probe or touch any other electrical components.
5. CLEAN AROUND THE SENSOR AND CONNECTOR — Using a dry cloth or a soft brush, carefully clean any grease or debris from around the sensor probe and its base mounting point inside the oven. Grease build-up directly on or around the probe can in rare cases affect its readings. Do not use water or spray cleaners inside the oven near the sensor.
6. TEST THE NTC SENSOR RESISTANCE WITH A MULTIMETER (COMPETENT DIY) — If you own a multimeter and are comfortable using one, you can test the sensor. With the oven cold and fully isolated from the mains: unscrew the NTC probe (usually one or two Torx or Phillips screws), disconnect its plug, and place the multimeter probes across the sensor terminals. At room temperature (around 20°C), a healthy Beko NTC sensor typically reads approximately 10,000–12,000 ohms (10–12 kΩ). A reading of zero (short circuit) or infinite (open circuit / OL) confirms the sensor has failed and needs replacing. You will need a multimeter and a Torx T20 or Phillips PH2 screwdriver.
7. REPLACE THE NTC TEMPERATURE SENSOR (COMPETENT DIY — ELECTRIC OVENS ONLY) — If the sensor has tested as faulty, replacement is a manageable DIY job on a Beko electric oven. Source a genuine Beko NTC sensor for your exact model number (found on the rating plate inside the oven door frame). Genuine Beko parts or quality equivalents are available from UK suppliers such as eSpares, 4ourhouse, or BuySpares for approximately £15–£35. With the appliance fully isolated from mains power: remove the old sensor (1–2 screws), unplug its wiring connector, plug in the new sensor connector, mount it with the screws, and restore power to test. Always use a part matched to your specific model number.
8. IF F02 PERSISTS AFTER SENSOR REPLACEMENT — If you have fitted a confirmed-correct replacement sensor and the F02 code still appears, this points to either a damaged wiring harness between the sensor and the control board, or a faulty control board (PCB) itself. Both of these repairs require a qualified appliance engineer — do not attempt to open the main electrical housing or replace the PCB yourself.
9. DO NOT ATTEMPT GAS COMPONENTS — If your Beko cooker has a gas hob combined with an electric oven, the F02 code relates exclusively to the electric oven section. However, if you are in any doubt about which component is involved, or if your appliance is a gas oven (not merely a gas hob), stop all DIY and contact a Gas Safe registered engineer immediately.
📞 When to call a professional
Call a qualified appliance repair engineer if: the F02 code returns immediately after a full power reset; the sensor tests as healthy on a multimeter but F02 persists; you have fitted a new correctly-matched NTC sensor and the error is still present (indicating a wiring or PCB fault); or you are uncomfortable working with the internal wiring of the appliance at any stage. When you call, tell the engineer: ‘My Beko oven is displaying error code F02, which I understand relates to the NTC temperature sensor. I have already tried a power reset [and/or replaced the sensor — if applicable] and the fault persists.’ This will save diagnostic time and may reduce your call-out charge. If your cooker has a gas oven (as opposed to a gas hob with electric oven), you must use a Gas Safe registered engineer — never attempt internal repairs yourself on any gas cooking appliance.

⚖️ Repair or replace?
For most UK homeowners, repair is the right call for a Beko cooker showing F02 — provided the appliance is under eight years old and otherwise in good working order. Beko is one of the most widely sold appliance brands in the UK, and NTC temperature sensors are readily available as genuine or quality-equivalent parts, making this a cost-effective repair. If the fault is simply the NTC sensor, a DIY fix costs as little as £15–£35 in parts and an hour of your time. A professional repair (call-out, diagnosis, and sensor replacement) typically runs £80–£150 depending on your region and engineer. However, if the diagnosis reveals the main PCB (control board) has failed, costs rise sharply — PCB replacements can reach £150–£250 in parts alone, plus labour. At that point, weigh it against the cost of a new mid-range Beko electric cooker, which starts at around £350–£500. The general rule of thumb: if the repair quote exceeds 50% of the cost of an equivalent new appliance, replacing is more sensible — especially if the cooker is over seven to ten years old. Beko’s parts availability is generally good for models up to around eight years old; older models may require compatible aftermarket sensors.
