Oven
F2
The F2 error code on a Candy oven points to a problem with the oven’s temperature sensor (also called the NTC probe or thermostat probe), meaning the appliance cannot accurately read the internal temperature and has shut down as a safety precaution. It can feel alarming mid-cook, but in many cases this is one of the more straightforward oven faults to diagnose and resolve. In this guide, you’ll learn exactly what’s causing the F2 error on your Candy oven, which fixes you can safely attempt yourself, and when it’s time to call in a professional — along with honest UK repair costs throughout.
What does this error mean?
The F2 error code on Candy ovens (including models in the FCP, FCT, OVG, and built-in multifunction ranges) indicates a fault with the NTC temperature sensor — the small probe inside the oven cavity that constantly monitors internal temperature and feeds that data back to the control board. When the control board receives a reading that is outside the expected range — either an open circuit (no signal at all) or a short circuit (a nonsensical reading like -40°C or above 300°C) — it triggers the F2 error and disables heating as a safety measure. In plain terms: your oven doesn’t know how hot it is, so it refuses to heat. This is the appliance protecting itself and you from a potential runaway temperature situation. The oven is not necessarily broken beyond repair — it’s doing exactly what it should by stopping and alerting you.

🔍 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 if it’s a built-in model), wait a full 5 minutes, then switch it back on. This clears any transient electronic fault caused by a power surge or temporary sensor glitch. If the F2 error disappears and the oven heats normally, monitor it over the next few uses to confirm it was a one-off.
Step 2 — Check your circuit breaker and power supply: Go to your consumer unit and check that the circuit breaker for your oven hasn’t tripped. Reset it if needed, then try the oven again. An unstable power supply can cause persistent error codes that have nothing to do with the oven itself.
Step 3 — Consult your Candy oven’s user manual: Locate your specific model number (printed on the rating plate inside the oven door frame) and check the error code section of the manual. Some Candy models have a slightly different reset procedure — such as holding the function selector and temperature dial simultaneously for 5 seconds — which may clear a stored fault code.
Step 4 — Inspect the oven cavity for visible sensor damage: Open the oven door and look toward the back wall or top of the oven cavity for the NTC temperature sensor — it typically looks like a small metal probe (roughly 3–5cm long) secured with one or two screws. Check whether it is visibly damaged, burnt, or has come loose from its mounting. Do not touch internal wiring at this stage.
Step 5 — Check for moisture or grease around the sensor: If you’ve recently steam-cleaned the oven or used a lot of water internally, use a dry cloth to carefully wipe around the sensor probe and its immediate surroundings. Allow the oven to air-dry with the door open for 30–60 minutes before retrying. Do not use a hairdryer or apply heat.
Step 6 — Test the NTC sensor resistance with a multimeter (moderate DIY): If you’re comfortable using a multimeter, you can test the sensor’s resistance without opening the main electrical components. First, isolate the oven at the wall. Locate the sensor probe in the oven cavity, unscrew it (usually a single Torx or Phillips screw), and carefully pull it forward to expose the connector — you do not need to open the back panel. At room temperature (around 20°C), a healthy Candy NTC sensor should read approximately 10,000–12,000 ohms (10–12 kΩ). A reading of zero (short circuit) or infinite resistance (open circuit) confirms a failed sensor. You’ll need a basic digital multimeter (£10–£25 from Screwfix or Amazon).
Step 7 — Replace the NTC temperature sensor if confirmed faulty: Candy NTC oven sensors are widely available from UK spares suppliers including 4ourhouse, eSpares, and Repair Clinic. Search using your full model number to ensure compatibility — prices typically range from £10–£30. Fitting is straightforward: disconnect the old sensor, connect the new one to the same harness connector, and secure it with the original screw. No specialist tools required beyond a screwdriver. After fitting, restore power and check whether the F2 error has cleared.
Step 8 — Inspect the wiring connector at the sensor: While you have the sensor removed (Step 6 or 7), visually inspect the plastic wiring connector for any signs of corrosion, burnt pins, or loose terminals. If a terminal looks loose, you can gently press it back into place with a small flathead screwdriver. If you see burning or melting, stop — this indicates a more serious wiring fault that needs a professional.
Step 9 — If the error persists after a new sensor, do not attempt further DIY: A persistent F2 after a confirmed sensor replacement almost certainly points to a faulty PCB (control board) or a deeper wiring harness fault. At this point, the repair involves accessing and testing internal electrical components — this is not a safe DIY task and should be handed to a qualified appliance engineer.
📞 When to call a professional
Call a professional appliance engineer if: the F2 error returns immediately after a hard reset and there are no obvious visible causes; your multimeter test shows the sensor is reading correctly but the error persists (pointing to a PCB fault); you notice any burnt smell, visible scorching on wiring, or melted plastic connectors when inspecting the sensor; the oven is a gas-electric combination model (any gas component must be handled by a Gas Safe registered engineer); or you are not confident working with the sensor connector and wiring. When you call, tell the engineer: the exact error code (F2), your full Candy oven model number (from the rating plate inside the door frame), what you’ve already tried (reset, sensor inspection, possibly a sensor replacement), and whether the error appeared suddenly or has been intermittent. This will save diagnostic time and likely reduce your call-out charge. You can find Gas Safe registered engineers at gassaferegister.co.uk, and qualified appliance repair engineers through Which? Trusted Traders or local directories.
⚖️ Repair or replace?
For a Candy oven showing F2, the repair versus replace decision largely comes down to the oven’s age and what part has failed. If the fault is a failed NTC sensor — by far the most common cause — this is a low-cost fix (£10–£30 for the part) and well worth doing on any oven under 10 years old. Candy is part of the Haier group and spare parts for most Candy oven models remain readily available in the UK, typically with next-day delivery from major spares stockists. If the fault turns out to be a faulty PCB (control board), costs rise significantly: a new Candy oven PCB typically costs £60–£130 for the part, plus £60–£100 for a professional to fit it. On an oven that is over 8–10 years old, a PCB repair at £150–£220 all-in becomes harder to justify against the cost of a new mid-range Candy or equivalent oven (£300–£600). Our recommendation: if the oven is under 7 years old, always repair — a sensor fix is excellent value. Between 7–10 years, repair if it’s a sensor; think carefully about a PCB. Over 10 years old with a PCB fault, replacing is likely the more economical long-term choice.
