Oven
F1
The F1 error code on a Beko oven points to a fault with the oven’s temperature sensor — specifically, the appliance has detected that the sensor circuit is either open (broken) or giving a reading that’s out of the expected range. It’s one of the more common Beko oven faults and, while it will prevent your oven from heating safely, it’s not a dangerous emergency in most cases. In this guide, you’ll learn exactly what the F1 code means, the most likely reasons it’s appeared, what you can safely try yourself, and when it’s time to call in a professional.
What does this error mean?
The F1 code on Beko ovens is a temperature sensor error. Inside every electric oven there is a small probe — usually called an NTC sensor or thermostat probe — that continuously monitors the internal cavity temperature and reports back to the control board. When the control board receives a reading that falls outside its acceptable range (or receives no reading at all), it flags an F1 fault and shuts the heating elements down as a safety precaution. In plain terms: the oven’s ‘thermometer’ has either failed, become disconnected, or is sending back nonsense data, so the oven has refused to operate rather than risk overheating your kitchen. On some Beko models the code may also appear as ‘F-1’ or flash alongside a beeping alarm. This applies predominantly to Beko electric fan ovens and electric range cookers; if you have a Beko gas oven and are seeing this code on the electric grill or fan element side, the same logic applies to that electric circuit.
Est. repair cost
DIY sensor replacement: £10–£25 for the part. Professional repair (sensor replacement): £80–£130 all-in. Professional repair (PCB replacement): £150–£220 all-in, depending on model and engineer call-out rates in your area.
🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Perform a hard reset: Switch the oven off at the wall socket (or at the fuse spur or circuit breaker in your fuse box), wait a full 10 minutes, then switch it back on. This clears any temporary electrical glitch or power-surge-induced fault. If the F1 code disappears and the oven heats normally, monitor it closely over the next few uses.
Step 2 — Check the oven is on a dedicated circuit or socket: Plug your oven back in and confirm no other high-draw appliances are sharing the same circuit. An unstable power supply can cause intermittent sensor errors. If you have a fused connection unit (FCU), check the fuse inside it — a 13A fuse is standard for most built-in electric ovens.
Step 3 — Locate the temperature sensor: On most Beko built-in ovens, the NTC sensor is a thin metal probe (roughly 5–8 cm long) mounted on the back wall of the oven cavity, usually held in place by one or two small Torx or Philips screws. You’ll need a Torx T20 or a Philips screwdriver. Make absolutely sure the oven is switched off at the mains before touching anything inside the cavity.
Step 4 — Visually inspect the sensor and its wiring: With the oven completely cold and unplugged, remove the sensor screws and gently pull the sensor forward into the cavity. Inspect the probe for any obvious signs of damage — cracking, burn marks, or corrosion. Then carefully trace the wire back as far as you can see toward the rear wall and check for any visible scorching, fraying, or kinking.
Step 5 — Check the wiring connector: The sensor connects to the oven’s internal wiring via a small push-fit connector (usually located just behind the back cavity wall, accessible from inside the cavity or, on some models, from behind the back panel). If you can reach it safely without opening sealed electrical enclosures, firmly reseat the connector on both sides. A loose connection here is a surprisingly frequent cause of F1.
Step 6 — Test the sensor with a multimeter (DIY-confident users only): Set a multimeter to the resistance (Ω) setting. Disconnect the sensor connector and place the probes on the two sensor terminals. At room temperature (around 20°C), a healthy Beko NTC sensor should read approximately 4,000–6,000 ohms (4–6 kΩ). A reading of zero (short circuit) or ‘OL’ / infinite resistance (open circuit) confirms the sensor has failed and needs replacing. No tools other than a basic multimeter are needed.
Step 7 — Replace the temperature sensor if faulty: Genuine Beko replacement NTC oven sensors are widely available from UK appliance parts suppliers such as eSpares, 4WhitGoods, and BuySpares, typically for £10–£25 depending on your model. Find your model number (printed on a label inside the oven door frame) and order the correct part. Fitting is the reverse of removal — unplug the old sensor, plug in the new one, screw it back into the cavity wall, and restore power. This is a straightforward DIY repair requiring only a screwdriver.
Step 8 — Clear the error and test: After fitting the new sensor, restore power at the mains, set the oven to 180°C fan, and allow it to reach temperature. The F1 code should be gone. If your Beko model requires a manual error clear, consult your user manual — on most models the fault clears automatically once the underlying issue is resolved.
Step 9 — If F1 persists after a confirmed good sensor, stop DIY: A persistent F1 code with a correctly tested and fitted sensor almost certainly points to a failed control board (PCB). Replacing a PCB involves working directly with mains-voltage electrical components inside the appliance. This is not a safe DIY task for most homeowners — call a qualified appliance engineer at this point.
📞 When to call a professional
Call a professional appliance repair engineer if: the F1 code returns immediately after a hard reset; the sensor tests faulty but you’re not comfortable replacing it yourself; you’ve fitted a new sensor and the F1 code is still showing; or there are any signs of burning smells, scorch marks, or melted wiring inside the oven cavity. When you call, tell the engineer: ‘My Beko oven is showing an F1 error code, which I understand is a temperature sensor fault. I’ve already tried a hard reset and [describe what else you’ve done]. I’d like the sensor and wiring inspected, and possibly the PCB checked.’ This will save diagnostic time and money. For UK residents, you can find reputable local appliance engineers through Checkatrade, Which? Trusted Traders, or by contacting Beko’s own UK customer service line (0333 207 4444) to ask about their authorised repair network.
⚖️ Repair or replace?
If your Beko oven is under 5 years old, repair is almost always the right call. A temperature sensor replacement is a low-cost, readily available fix, and Beko parts supply in the UK is generally good. If the fault turns out to be a PCB replacement, weigh up the cost carefully — a new PCB for a Beko oven typically costs £60–£120 for the part alone, plus labour. For an oven that’s 8–10 years old or more, a PCB repair bill pushing £150–£200 all-in starts to make replacement worth considering, especially as budget Beko electric ovens can be purchased new from UK retailers for as little as £200–£350. As a general rule of thumb used by UK appliance engineers: if the repair costs more than 50% of the cost of a comparable new appliance, replacement is the smarter long-term choice. Beko ovens generally have a good reputation for reliability in the mid-budget segment, and parts availability is solid, which tips the balance toward repair in most F1 fault scenarios.
