Oven
F6
The F6 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?
The F6 code means your Beko oven’s control board has detected an abnormal reading from the temperature sensor, also known as the NTC (Negative Temperature Coefficient) probe. This probe monitors the internal oven temperature and feeds that data back to the control board — if the reading is out of range, shorted, or absent entirely, the oven throws F6 and shuts down the heating element as a safety precaution. In short: the oven can’t confirm its own temperature, so it refuses to heat.

🔍 Likely causes
🛠️ Step-by-step fix
Power cycle the oven: switch it off at the wall socket or trip the circuit breaker, wait 5 minutes, then restore power. A one-off software glitch can trigger F6 and a reset clears it. If the code doesn’t return, monitor the oven for a few uses.
Check the oven’s manual or Beko’s support website to confirm F6 maps to a temperature sensor fault on your specific model — Beko’s code definitions can vary slightly by range.
Inspect the NTC sensor visually: with the oven fully unplugged, locate the probe (typically a small metal spike mounted inside the oven cavity, near the back wall or top). Look for obvious burn marks, physical damage, or a broken tip.
Check the sensor connector: trace the thin cable from the probe through to where it plugs into the control board (usually behind the back panel). Press the connector firmly home and check for any scorched or broken wires. Refit the back panel and retest.
Test the NTC sensor resistance with a multimeter: a healthy Beko NTC probe typically reads around 10,000 ohms (10kΩ) at room temperature (~20°C). A reading of zero (short) or infinite (open circuit) confirms a failed sensor — replace it.
Replace the NTC temperature sensor: genuine Beko replacement probes cost £15–£35 online (use your full model number from the oven door frame). The sensor is usually secured by one screw and one connector — this is a straightforward DIY job on most Beko models, with the oven unplugged throughout.
📞 When to call a professional
If replacing the NTC sensor doesn’t clear the F6 code, the fault likely lies with the wiring harness or the main control board (PCB) — both require disassembly of electrical components inside the appliance and should be handled by a qualified appliance engineer. Call a repair technician and tell them: ‘My Beko oven is showing error code F6, I’ve already replaced the NTC temperature sensor and the fault persists.’ If your oven is a gas range with an electric oven cavity, the same advice applies — the gas components must only be touched by a Gas Safe registered engineer.
⚖️ Repair or replace?
A new NTC sensor is £15–£35 DIY, making self-repair excellent value if that’s the root cause. A professional repair (including call-out, labour, and parts) typically runs £80–£160 in the UK — worth it if your oven is under 8 years old. If the control board needs replacing, parts alone can reach £60–£120 plus labour, so on an oven older than 8–10 years, weigh that cost against a new built-in electric oven starting from around £250–£350.
