What Sensor fault means on a Electrolux dryer

The Sensor fault code on an Electrolux dryer indicates a problem with the humidity sensor system, which the dryer relies on to detect moisture levels in the drum and determine when laundry has reached the target dryness level. The humidity sensor typically consists of two metal sensor bars mounted inside the drum that measure the electrical conductivity of the laundry as it tumbles past them. When fabric is wet, it conducts electricity between the bars; as it dries, conductivity drops and the control board adjusts the cycle accordingly.

This fault code does not always indicate a hardware failure. The dryer may display this message when it is run completely empty or when laundry that is already dry is placed inside the drum. In these cases, the sensor bars detect no conductivity at all, and the control board may interpret this absence of signal as a sensor malfunction rather than a true load condition.

If the fault appears during a normal cycle with a wet load, the cause is more likely a genuine sensor issue, such as contaminated or corroded sensor bars, a wiring fault between the sensor and the control board, or a failed sensor circuit on the board itself. The first step is simply to open the dryer door, which should clear the message. If the code persists after opening the door, the control board and sensor circuit require further inspection by a qualified technician.

Common causes of Sensor fault

  1. 01

    Running the dryer empty or with dry laundry

    Wiring / connection

    If the drum contains no wet laundry, the humidity sensor detects zero conductivity and can trigger this fault. This is the most common and harmless cause, and opening the door should clear the message immediately.

  2. 02

    Contaminated or coated sensor bars

    Wiring / connection

    Residue from fabric softener sheets or detergent buildup on the sensor bars insulates them and prevents accurate conductivity readings. The bars can usually be cleaned with a soft cloth and a small amount of rubbing alcohol.

  3. 03

    Faulty or failed humidity sensor

    Part replacement

    The sensor bars or the sensor assembly itself may have failed electrically, producing no signal or an out-of-range signal to the control board. Replacement of the sensor assembly would be required.

  4. 04

    Wiring fault between sensor and control board

    Wiring / connection

    Damaged, loose, or corroded wiring connecting the humidity sensor to the control board can interrupt the signal and trigger this fault. A technician would need to inspect the wiring harness and connectors.

  5. 05

    Control board fault

    Part replacement

    If the sensor and all associated wiring test correctly, the fault may originate in the control board circuit that processes the sensor signal. Board-level faults typically require professional diagnosis and possible board replacement.

Frequently asked questions about Sensor fault

What does Sensor fault mean on a Electrolux dryer?
This code means the dryer has detected a problem with its humidity sensor, which measures moisture levels in the drum to control drying time. It can appear when the dryer is run empty, when laundry is already dry, or when there is a genuine issue with the sensor or its wiring. Opening the dryer door should clear the code in most cases. If it does not disappear after opening the door, a service technician should inspect the unit.
Can I fix a Sensor fault on my Electrolux dryer myself?
In many cases, yes. If the code appeared because the dryer was run empty or with dry clothes, simply opening the door will clear it. If the sensor bars inside the drum are dirty or coated with fabric softener residue, cleaning them gently with rubbing alcohol may resolve the issue. However, if the fault persists after these steps, further diagnosis involving wiring or internal components should be handled by a qualified technician.
Is it safe to keep using my dryer when a Sensor fault is showing?
You should not continue running the dryer while this fault is active, as the humidity sensor may not be controlling the cycle correctly. Without accurate moisture detection, the dryer could run longer than needed, potentially overheating fabrics or consuming excess energy. Clear the fault first, and only resume use if the code does not return during a normal cycle.
Will resetting my Electrolux dryer clear the Sensor fault code?
Opening the dryer door is the recommended first step and should clear the message if the cause is a non-fault condition such as an empty drum or already-dry laundry. A full power reset may also temporarily clear the code, but if the underlying sensor problem remains, the fault will return. A persistent code that does not clear with these steps requires service.
How much does it cost to repair a Sensor fault on an Electrolux dryer?
Repair costs vary depending on the root cause. If the sensor bars only need cleaning, there is no parts cost involved. Replacing a humidity sensor assembly typically costs in the range of $20 to $80 for the part, plus labor if a technician performs the work. If the control board is at fault, parts and labor combined can range from $150 to $400 or more depending on the model and service rates in your area.
