Air Fryer
E2
The E2 error code on a Gourmia air fryer indicates a temperature sensor fault — specifically, the appliance is detecting that its internal NTC (thermistor) temperature sensor has failed, is reading an abnormal value, or has become disconnected. It sounds alarming, but in many cases this is a fixable problem that doesn’t mean your air fryer is destined for the bin. In this guide, you’ll learn exactly what triggers the E2 code, what you can safely check yourself at home, and when it’s time to seek a professional repair or consider a replacement.
What does this error mean?
The E2 error on Gourmia air fryers is a temperature sensor error. Your air fryer relies on a small component called an NTC thermistor — a temperature-sensitive resistor — to constantly monitor the heat inside the cooking chamber. This sensor feeds live temperature data to the appliance’s control board, which uses it to regulate the heating element and keep cooking temperatures accurate and safe. When the control board receives a reading that is out of the expected range — either because the sensor has failed, its wiring has come loose, or it is reading a short circuit or open circuit — it throws the E2 code and shuts the appliance down as a safety precaution. In short: your Gourmia air fryer cannot confirm it is operating at a safe temperature, so it has stopped itself from running.
Est. repair cost
DIY thermistor replacement: £5–£15 for the part. Professional repair: £50–£80 for labour plus parts. New Gourmia air fryer: £40–£120.
🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Unplug the appliance immediately and let it cool for at least 30 minutes. Never attempt to inspect or reset the air fryer while it is plugged in or still warm. Safety first.
Step 2 — Perform a hard reset. Once cooled, plug the air fryer back in, press and hold the power button for 5–10 seconds, then release. Some Gourmia models clear transient sensor errors with a full power cycle. If the E2 code does not return, run a short test cook to confirm it is resolved.
Step 3 — Check the air vents for blockages. Locate the air intake vents (usually on the rear or underside of the unit) and the exhaust vent (typically on the top or rear). Use a dry cloth or a soft brush to clear any dust, grease, or debris. A blocked vent causes heat build-up that can trigger sensor errors.
Step 4 — Deep clean the cooking chamber and basket. Remove the basket and drawer, wash them thoroughly, and use a damp cloth to carefully wipe down the inside of the cooking cavity, paying particular attention to the area around the heating element where the thermistor is located. Grease coating the sensor can cause false E2 readings. Do not spray water directly into the unit.
Step 5 — Inspect the sensor visually (without opening the casing). On many Gourmia models, you can see the thermistor — a small probe or bead on a thin wire — by looking into the cooking chamber near the top or rear wall. Check whether it appears blackened, broken, or heavily coated in residue. A visually damaged sensor will need replacing.
Step 6 — Check your warranty. Gourmia air fryers sold in the UK come with a minimum 12-month manufacturer’s warranty, and under the UK Consumer Rights Act 2015 you may have up to six years of legal protection for faulty goods. If your unit is relatively new, contact the retailer or Gourmia’s UK support before spending any money on repairs.
Step 7 — Source a replacement NTC thermistor if the sensor appears faulty. Gourmia replacement thermistors are available on Amazon UK and eBay, typically priced between £5 and £15. Make sure to match the resistance specification (usually 100kΩ at 25°C for Gourmia models) and the connector type to your specific model number, which is printed on the base of the unit.
Step 8 — Replace the thermistor (CAUTION — only attempt this if you are confident with basic electronics). To access the sensor, you will need to open the outer casing of the air fryer using a Phillips screwdriver. Disconnect the old sensor, fit the new one, reconnect the wiring loom, and reassemble. IMPORTANT: If you are not comfortable working inside electrical appliances, skip this step and go straight to Step 9 — do not attempt internal repairs.
Step 9 — If the E2 code persists after cleaning and a reset, and you are not replacing the sensor yourself, contact a local appliance repair technician. Provide them with the model number (e.g. GAF698 or similar), the E2 error code, and a summary of what you have already tried.
📞 When to call a professional
Stop DIY attempts and call a professional repair technician if: the E2 error code returns immediately after a hard reset and thorough clean; you have visually inspected the sensor and it appears burned or broken; or you are not confident opening the appliance casing. You should also seek professional help if you notice any signs of scorching, melted plastic, or burning smells, which could indicate wider electrical damage beyond just the sensor. When calling a technician, tell them: ‘My Gourmia air fryer is displaying an E2 error code, which I understand is a temperature sensor fault. I have already tried a hard reset and cleaned the unit but the error persists.’ This gives them everything they need to diagnose the fault efficiently. For Gourmia warranty claims in the UK, contact the retailer where you purchased it first — under the Consumer Rights Act 2015, the retailer (not the manufacturer) is your first point of contact for faulty goods.
⚖️ Repair or replace?
Gourmia air fryers sold in the UK typically retail between £40 and £120 depending on the model and capacity. This makes the repair-versus-replace decision more nuanced than with premium appliances. If your unit is under 12 months old, pursue a warranty claim or return before spending anything on repairs — you are legally entitled to a repair, replacement, or refund. If your appliance is 1–2 years old and the fault is just the thermistor, a DIY part replacement costing £5–£15 is almost always worth attempting, as the repair is straightforward for anyone comfortable with basic electrical tasks. If the control board has failed, professional repair costs (£50–£80 labour plus parts) will likely exceed or come close to the cost of a brand-new Gourmia, making replacement the more sensible option. For units over 3 years old showing an E2 fault, consider that other components may be approaching end of life too — replacing the whole unit with a current model is often the better long-term value, particularly given how competitive air fryer pricing has become in the UK market. Parts availability for Gourmia can be inconsistent in the UK, which is another factor worth weighing before committing to a professional repair.
