Cooker
F05
The F05 error code on a Beko cooker indicates a fault with the oven’s temperature sensor (NTC probe), meaning the appliance cannot accurately read or regulate heat. It’s a moderately serious fault — the oven will typically stop working or refuse to heat until it’s resolved.
What does this error mean?
F05 signals that the oven control board has detected an abnormal reading from the NTC (Negative Temperature Coefficient) temperature sensor inside the oven cavity. This sensor constantly relays the internal temperature back to the control board so it can maintain the correct heat. When the board receives a reading that’s out of range — either a short circuit or an open circuit in the sensor — it throws the F05 code and disables the heating elements as a safety precaution.

🔍 Likely causes
🛠️ Step-by-step fix
Power off and reset: Switch the cooker off at the wall socket (or trip the circuit breaker), wait 5 minutes, then restore power. A transient fault can sometimes clear itself — if F05 is gone, monitor the oven through a full cooking cycle.
Check the oven cavity for visible damage: Open the oven door and look at the rear wall or roof for a small metal probe (the NTC sensor). Confirm it’s still clipped securely into its bracket and not visibly burnt or corroded.
Inspect the sensor connector: If you’re comfortable doing so, pull the cooker away from the wall, remove the back panel screws, and locate the sensor’s wiring plug. Check for loose, burnt, or corroded pins and reseat the connector firmly. Replace the back panel and retest.
Test the NTC sensor with a multimeter (DIY-confident users only): Disconnect the sensor plug and measure resistance across the two sensor terminals. A healthy Beko NTC sensor typically reads around 10,000 ohms (10kΩ) at room temperature (~25°C). A reading near zero (short) or infinite (open circuit) confirms a faulty sensor.
Replace the NTC sensor: Beko NTC oven sensors are widely available online for £10–£25. Disconnect power, unclip the sensor from inside the oven cavity, unplug the connector, and fit the new part in reverse order. This is a straightforward like-for-like swap requiring no specialist tools.
If the new sensor doesn’t clear F05, stop and call a professional — the fault likely lies with the wiring harness or the main PCB, which require specialist diagnosis.
📞 When to call a professional
Call a qualified appliance engineer if replacing the NTC sensor does not clear the error, or if you find burnt or melted wiring behind the appliance. Tell them: ‘My Beko oven is displaying error code F05, I’ve already replaced the NTC temperature sensor and the fault persists.’ This helps them arrive prepared to test the wiring loom and PCB rather than starting from scratch.
⚖️ Repair or replace?
A professional repair for an F05 fault — typically covering a sensor replacement or wiring repair — costs around £80–£150 including labour. If the main control board (PCB) has failed, expect £150–£250. As a rule of thumb, if your Beko cooker is over 8 years old and the repair quote exceeds £150, replacement is the more economical choice — a comparable new Beko single oven starts at around £250–£350.
