Cooker
E06
The E06 error code on a Rangemaster cooker points to a fault with the oven’s temperature sensor or the control board’s ability to read it — meaning your oven may not heat correctly or could cut out altogether. It’s one of the more common fault codes on Rangemaster range cookers, and while it can sound alarming, it’s often fixable without spending a fortune. In this guide, you’ll learn exactly what E06 means, the most likely causes on Rangemaster appliances, what you can safely try yourself, and when it’s time to call in a professional.
What does this error mean?
On Rangemaster range cookers — including popular models in the Classic, Professional, and Excel ranges — the E06 error code indicates a problem with the oven temperature sensor (also called a thermocouple probe or NTC sensor, depending on your model). Specifically, the control board is detecting that the sensor’s resistance reading is either out of the expected range, giving an implausible temperature reading, or has lost its signal entirely. In plain English: the oven’s ‘thermometer’ is either broken, disconnected, or sending back a reading the control board doesn’t trust. As a safety measure, Rangemaster’s electronics will prevent the oven from operating normally — or shut it down — until the issue is resolved. This is by design: running an oven with a faulty temperature sensor could result in dangerous overheating or food that’s never properly cooked.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Perform a hard reset: Switch the cooker off at the wall socket or circuit breaker, wait a full 5 minutes, then switch it back on. This clears any temporary software glitch caused by a power fluctuation. If E06 disappears and does not return, monitor the oven over the next few uses.
Step 2 — Check the trip switch on your consumer unit: Before assuming the worst, go to your fuse box and confirm the circuit breaker for your cooker hasn’t partially tripped. Reset it firmly if needed, then retry the appliance.
Step 3 — Locate the temperature sensor: On most Rangemaster models, the oven temperature sensor is a thin metal probe (roughly 3–4 cm long) mounted on the back wall of the oven cavity, usually in the upper-left or upper-right corner. You’ll see it held in place by one or two small screws and connected to a wire disappearing through the oven wall.
Step 4 — Inspect the sensor for visible damage: With the oven completely cold and unplugged from the mains, look closely at the probe and its wiring. Check for any signs of burning, melting, or physical damage to the sensor body itself. If it looks charred or the probe tip is visibly corroded, the sensor needs replacing.
Step 5 — Check the sensor connector inside the oven: Gently follow the sensor wire to where it exits through the oven wall or into a connector. Ensure the connector is firmly seated and hasn’t come loose. You can carefully press it back in if it’s worked loose — no tools required. Important: only do this with the appliance fully unplugged.
Step 6 — Clean around the sensor: If there is heavy grease build-up around the sensor probe, carefully clean it with a damp cloth and a small amount of oven cleaner (ensuring the oven is cold and unplugged). Avoid spraying cleaner directly onto the connector or wiring.
Step 7 — Test the sensor resistance with a multimeter (competent DIYers only): If you own a multimeter and are comfortable using one, you can test the sensor. Unplug the oven, disconnect the sensor connector, and place the probes on the two sensor terminals. At room temperature (around 20°C), a healthy Rangemaster NTC sensor should read approximately 1,000–1,100 ohms. A reading of zero (short circuit) or infinite resistance (open circuit) confirms the sensor has failed and needs replacing.
Step 8 — Replace the temperature sensor (DIY-safe for competent homeowners): Replacement Rangemaster oven temperature sensors are widely available from UK spares suppliers such as eSpares, 4Rangemaster, or Rangemaster’s own parts line, and typically cost £15–£40. With the oven unplugged, remove the one or two retaining screws, pull the old sensor out, disconnect the wiring, connect the new sensor, refit the screws, and restore power. Always use the correct part number for your specific model (found on the rating plate inside the door frame).
Step 9 — If the error persists after sensor replacement, stop DIY here: A persisting E06 after a confirmed sensor replacement strongly suggests a wiring harness fault or a failed control board (PCB). Both of these require opening the appliance’s back panel and working near live electrical components — this is not a safe DIY task. At this point, call a qualified appliance repair engineer.
Step 10 — If your Rangemaster has a gas oven (dual fuel model): The temperature sensor on a gas oven is subject to the same fault modes, but because you will be working in proximity to the gas system during any back-panel repair, do not attempt anything beyond the external sensor check described above. Contact a Gas Safe registered engineer for all further investigation.
📞 When to call a professional
You should stop DIY and call a qualified appliance repair engineer if: the error code returns after a hard reset and a new sensor has been fitted; the sensor wiring looks burnt or melted anywhere along its length; you are not confident using a multimeter or handling electrical connectors; or the fault appears to be with the control board (PCB). When you call, tell the engineer: ‘My Rangemaster [model name, e.g. Classic 110] is showing an E06 error code. I’ve already done a hard reset and checked/replaced the oven temperature sensor, but the fault persists.’ This will save diagnostic time and cost. For dual-fuel or full gas Rangemaster models, contact a Gas Safe registered engineer — do not attempt to remove the back panel or touch any components beyond the steps described above.

⚖️ Repair or replace?
Rangemaster is a premium UK brand with excellent parts availability — sensors, wiring looms, and PCBs are all stocked by major UK spare parts suppliers, often with next-day delivery. This makes repair a strong first option in most cases.
**Repair is almost always the right choice if your Rangemaster is under 10 years old.** A sensor replacement you carry out yourself will cost £15–£40 in parts and about an hour of your time. A professional repair, including call-out, diagnosis, and labour, typically runs £80–£160 depending on your region and whether a PCB replacement is also needed (PCBs for Rangemaster can cost £80–£140 in parts alone).
**Consider replacing if:** the cooker is over 12–15 years old, the PCB has failed and a like-for-like board is no longer available, or if the repair quote exceeds 50–60% of the cost of a comparable new model. A new entry-level Rangemaster 90cm range cooker starts at around £900–£1,200, while mid-range models sit at £1,400–£2,500+. Given these prices, even a £200 repair on a well-maintained 8-year-old Rangemaster is usually excellent value.
