Fridge
E7
The E7 error code on an Electrolux fridge indicates a fault with the fridge compartment temperature sensor (NTC sensor), meaning the appliance cannot accurately monitor or regulate its internal temperature. This is a moderate fault — your fridge may still cool, but food safety is at risk if left unresolved.
What does this error mean?
The E7 code signals that the fridge section’s NTC (negative temperature coefficient) thermistor has either failed, is reading an implausible temperature, or has lost its connection to the control board. The fridge cannot confirm it is holding the correct temperature, so it may overcool, undercool, or behave erratically. In some Electrolux models, E7 specifically flags an open or short circuit in the fridge evaporator sensor circuit.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the fridge: unplug it from the mains, wait 5 minutes, then plug back in. If the E7 code clears and does not return within 24 hours, a power glitch was the cause — monitor it.
Check for ice build-up: open the fridge and inspect the back panel for excessive frost or ice. If heavily iced over, perform a manual defrost by unplugging the unit and leaving the door open for 24–48 hours with towels on the floor.
Locate the NTC sensor: it is typically clipped to the evaporator or mounted on the back wall inside the fridge compartment. Check that its wiring connector is firmly seated and that there is no visible corrosion, cracking, or damage to the wire.
Test the sensor resistance: using a cheap multimeter (available for £10–£20 from Screwfix or Amazon), disconnect the sensor and measure its resistance. A healthy Electrolux NTC sensor typically reads around 5,000–10,000 ohms at room temperature. A reading of zero (short) or infinite (open circuit) confirms a faulty sensor.
Replace the NTC sensor: genuine or compatible Electrolux fridge NTC sensors are available online for £10–£25. Unplug the fridge, unclip the old sensor, plug in the new one, and refit the back panel. This is a straightforward, low-risk DIY repair.
If the error returns after a new sensor is fitted, do not attempt to open or replace the main control board yourself — this requires a professional.
📞 When to call a professional
Call a qualified appliance engineer if the E7 error persists after replacing the NTC sensor, as the fault likely lies with the main control board or wiring loom — both of which require professional diagnosis. Tell the engineer: ‘My Electrolux fridge is showing error code E7, I’ve already replaced the NTC temperature sensor and the fault has returned.’ This will save diagnostic time and cost.
⚖️ Repair or replace?
A professional repair for an E7 fault (sensor replacement) typically costs £80–£130 call-out and labour, plus parts. If the control board needs replacing, expect £150–£250 all-in. For any Electrolux fridge over 8–10 years old where the repair quote exceeds £150, replacement is more economical — a decent mid-range fridge costs £300–£500 in the UK. For newer appliances still under warranty, contact Electrolux UK directly before spending anything.
