Oven
F7
The F7 error code on a Beko oven indicates a fault with the oven’s temperature sensor (NTC probe) or its circuit — it’s a moderately serious fault that will prevent the oven from heating safely until it’s resolved.
What does this error mean?
Your Beko oven continuously monitors its internal temperature using an NTC (Negative Temperature Coefficient) sensor. When the control board detects that the signal from this sensor is out of the expected range — either open circuit, short circuit, or reading an implausible temperature — it throws the F7 code and shuts down heating as a safety precaution. In plain terms: the oven doesn’t trust its own temperature readings, so it refuses to operate.

🔍 Likely causes
🛠️ Step-by-step fix
Power reset: Switch the oven off at the wall socket, leave it unplugged for 5 minutes, then power back on. A temporary glitch can occasionally clear the F7 code.
Check the sensor connector: Pull the oven away from the wall (unplug first), remove the back panel screws, and visually inspect the NTC sensor wiring connector at the back of the oven cavity. Reseat any loose connectors firmly.
Inspect the NTC sensor: The sensor is a small probe mounted inside the oven cavity, usually at the back or side wall. Look for visible damage — scorch marks, cracked casing, or a broken probe tip. A damaged sensor must be replaced.
Test the sensor with a multimeter: A healthy Beko NTC sensor reads approximately 990–1100 ohms at room temperature (around 20°C). If yours reads open circuit (OL) or significantly outside this range, the sensor has failed and needs replacing.
Replace the NTC sensor: Genuine Beko replacement sensors (check your model number on the rating plate inside the door frame) cost £15–£40 online. Unscrew the old sensor, unplug the connector, fit the new one in reverse order — this is a straightforward DIY task requiring only a Torx or Philips screwdriver.
If the error persists after a new sensor: Do not attempt to replace the control board yourself — this involves working with mains-voltage components and should be handled by a qualified appliance engineer.
📞 When to call a professional
If replacing the NTC sensor does not clear the F7 code, the control board (PCB) is likely at fault — call a reputable appliance repair engineer at this point, as PCB work involves mains-voltage components. When you call, tell them the exact model number (found on the rating plate inside the oven door frame), the error code (F7), and whether a new sensor has already been fitted. This will save diagnostic time and cost.
⚖️ Repair or replace?
A professional repair for an F7 fault — covering labour and parts — typically costs £80–£160 depending on whether it’s a sensor swap or a PCB replacement. If your Beko oven is under 5 years old, repair is almost always worth it. If it’s over 8–10 years old and the PCB has failed, a new mid-range Beko or equivalent oven (£300–£500) is likely the smarter long-term investment.
