Oven
E10
The E10 error code on a Samsung oven indicates a problem with the oven’s temperature sensor — the component responsible for monitoring the heat inside the cavity and feeding that information back to the control board. It’s one of the more common Samsung oven faults, and while it sounds alarming, it’s often something you can diagnose and even fix yourself. In this article, we’ll walk you through exactly what E10 means, the most likely causes, safe DIY steps to try, and when it’s time to call in a professional.
What does this error mean?
The E10 error code on Samsung ovens signals a fault with the oven temperature sensor, also known as the NTC (Negative Temperature Coefficient) thermistor. This small probe sits inside the oven cavity — usually at the back wall or top of the interior — and continuously measures the temperature, sending readings to the main control board. When the board receives a reading that falls outside the expected range (either too high, too low, or no signal at all), it throws the E10 code and typically shuts the oven down as a safety precaution. In plain terms: your oven thinks it can’t accurately measure its own temperature, so it refuses to operate. This could mean the sensor itself has failed, its wiring has come loose or been damaged, or — less commonly — the control board has developed a fault. The oven is not necessarily broken beyond repair; it’s simply protecting itself and you.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Perform a hard reset: Switch the oven off at the wall socket (or flip its dedicated circuit breaker in your fuse board), wait a full 5 minutes, then power it back on. This clears any temporary software glitch and is the fastest first step. No tools needed.
Step 2 — Check for moisture: If you’ve recently cleaned the oven with a lot of water or steam, leave the oven door open for an hour to allow any moisture inside the cavity to fully dry out, then attempt a reset again. Excess moisture can cause false sensor readings.
Step 3 — Inspect and clean the temperature sensor: With the oven completely cold and unplugged, locate the temperature sensor probe — it’s the small metal rod (roughly 5–8 cm long) mounted on the back wall inside the oven cavity, usually held in place by one or two small Phillips head screws. Gently wipe it down with a dry cloth to remove any grease or residue. Do not use water or cleaning sprays directly on the sensor.
Step 4 — Check the sensor mounting screws: While the oven is still unplugged, ensure the sensor is firmly seated and its retaining screws are tight. A loose sensor can give erratic readings. You’ll need a small Phillips screwdriver.
Step 5 — Test the sensor resistance (DIY-friendly if you own a multimeter): Unplug the oven, remove the sensor (two screws, then gently pull it forward slightly to access the wiring connector), and disconnect the sensor from its harness. Set your multimeter to the resistance (Ω) setting. At room temperature (around 20°C), a healthy Samsung NTC oven sensor should read approximately 1,000–1,100 ohms. A reading of zero (short circuit) or ‘OL’ (open circuit / no continuity) confirms the sensor has failed and needs replacing.
Step 6 — Replace the temperature sensor if it has failed: Samsung oven NTC sensors are widely available from UK appliance parts suppliers such as eSpares, 4Domestic, and BuySpares, typically priced at £15–£35. Make sure you search using your exact model number (found on the rating plate inside the oven door frame). Fitting is straightforward: unplug the oven, remove the two fixing screws inside the cavity, disconnect the old sensor’s wiring connector, connect the new one, and refit. No specialist tools required beyond a small screwdriver.
Step 7 — Inspect the sensor wiring harness: After removing the sensor, visually inspect the wiring running from the connector back into the appliance. Look for any signs of scorching, melting, or bare wires. If the wiring looks damaged, do not attempt to repair it yourself — this is a job for a qualified appliance engineer.
Step 8 — Power the oven back on and test: Once you’ve replaced the sensor or completed cleaning and checks, plug the oven back in, switch it on, and run it at 180°C for 10–15 minutes. Monitor whether the E10 code returns. If the oven heats normally and no error appears, the fault is resolved.
Step 9 — If E10 persists after sensor replacement, stop DIY: A persisting E10 code after a confirmed sensor replacement strongly suggests a control board fault. At this point, do not attempt to open the control board housing or probe any further electrical components. Call a qualified appliance engineer.
📞 When to call a professional
You should call a qualified appliance repair engineer if: the E10 code returns after you’ve replaced the temperature sensor with a confirmed good part; the wiring harness shows signs of burning or damage; you are not confident using a multimeter or working around electrical components; or the oven is a built-in electric model where accessing the rear wiring requires removing the appliance from its housing. When you call, tell the engineer: ‘My Samsung oven is showing error code E10. I believe it relates to the temperature sensor. I’ve already tried a hard reset [and replaced the sensor, if applicable] but the fault persists.’ This will save them diagnostic time and potentially reduce your call-out cost. Use a Which? Trusted Trader or Checkatrade-listed engineer, or contact Samsung’s own UK service line (0333 000 0333) to arrange an authorised repair.
⚖️ Repair or replace?
For most UK homeowners, repairing a Samsung oven showing E10 is the right call — provided the appliance is under 8–10 years old and the fault is limited to the temperature sensor. A genuine Samsung NTC sensor costs £15–£35 and is a beginner-level DIY repair. Even if you call an engineer, a sensor replacement including labour typically costs £80–£130, which is excellent value compared to replacing the oven. If the fault lies with the main control board, the calculation changes: a replacement Samsung PCB can cost £120–£250 for the part alone, and labour on top of that pushes total repair costs to £180–£350 or more. For an oven over 8 years old, spending that amount rarely makes financial sense. A decent freestanding electric oven from Samsung, AEG, or Bosch starts at around £400–£600 new, and you’d receive a fresh warranty. Samsung oven parts availability is generally good for appliances up to about 10 years old, but can become difficult beyond that point. Our recommendation: if the sensor fix resolves it, repair. If it’s a control board fault on an oven over 7–8 years old, seriously consider replacing.
