Electrolux Refrigerator Error Code freezer sensor fault

It means the NTC thermistor that monitors freezer air temperature is sending a signal outside the acceptable range to the control board. The board cannot produce an accurate temperature reading for the display as a result. Importantly, this sensor is used only for the display readout on these Electrolux models, so the freezer continues to cool and operate normally while the fault is present.

Yes, it is generally safe to continue using the appliance in the short term. The freezer air temperature sensor on this Electrolux model is used only for the temperature display, not for controlling the cooling cycle. Your food will remain cold, but you will not have a reliable temperature reading on the display until the sensor issue is resolved.

If only the NTC thermistor needs replacement, parts typically run in the range of $15 to $50 depending on the specific model. Professional labor to diagnose and replace the sensor can add $75 to $150 or more depending on your location and the service provider. If the fault turns out to involve the control board, repair costs will be higher, generally in the $150 to $350 range for parts and labor combined.

A power reset may temporarily clear the fault code from the display, but if the underlying sensor or wiring problem is still present, the fault will return. To permanently clear the error, the root cause, whether a failed sensor, damaged connector, or broken wire, must be identified and repaired first.

Start by pressing the function activation button to confirm the fault code, then locate the NTC sensor inside the freezer compartment and test its resistance with a multimeter to verify whether it falls within the expected range for the current temperature. Inspect the sensor connector and wiring harness for corrosion, damage, or loose connections. If the sensor tests as open or shorted, replacing the thermistor is the most direct repair.
