Possible Causes
Failed secondary NTC sensor, Loose or corroded connector, Damaged harness to control board, Control board sensor input failure
How to Fix / Troubleshooting
Safety first: Unplug the dryer before accessing internal components.
- Identify sensor: Consult the tech sheet for your Electrolux model to locate the specific NTC (often on the condenser or ambient air intake on heat pump models).
- Inspect and reseat connector: Disconnect and reconnect the sensor plug several times to clean contacts.
- Measure resistance: Compare the sensor's resistance at room temperature to the specified value. Replace if out of range.
- Check harness continuity: Verify continuity from the sensor to the control board. Repair any open or shorted wires.
If all checks pass and E73 remains, the main control board is likely at fault and should be replaced by a professional.
