Error Code: E72 Difficulty: Hard
Problem: The outlet thermistor is out of range / Problem with the NTC heater.
How to Fix E72 Error (Step-by-Step)
- Unplug the dryer from the power outlet for safety and confirm the error stays cleared during a full test cycle.
- Access the back of the dryer by removing the rear panel.
- Locate the outlet thermistor, which is a small sensor usually found on the exhaust housing.
- Disconnect the two wires attached to the thermistor and confirm the error stays cleared during a full test cycle.
- Use a multimeter to test the thermistor for continuity. A reading of approximately 50,000 ohms at room temperature is normal. If the reading is significantly different or shows no continuity, the thermistor needs replacement.
- Replace the faulty thermistor with a new one, ensuring the wires are securely connected.
- Reassemble the rear panel and plug the dryer back in to test its functionality.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Electrolux Dryer
Focused repair path: dryer airflow, heating, motor, sensor, and control checks. Do not treat the fault as reset-only if it keeps returning; use the failed function to choose the next test.
- Disconnect power before opening panels, then confirm whether the Electrolux dryer repeats the same code after a clean reset.
- Match the symptom to the part of the cycle or function that fails: fill, drain, heat, cool, spin, latch, ignite, fan, sensor, or control response.
- Inspect simple causes first: airflow, water supply, drain path, door closure, filter, venting, wiring connectors, and visible damage.
- Use meter testing or service diagnostics before replacing electronic controls, because wiring, switches, sensors, and loads can mimic board failure.
- Use the complete Electrolux dryer model number from the appliance tag before ordering any model-specific part.
Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Electrolux model number from the appliance tag before ordering.

When It’s Better to Replace Than Repair
Dryer repairs are often worth it for small parts, but repeated heating, motor, drum, or control failures can point toward replacement.
Confirm gas vs electric, venting, voltage, doorway clearance, and laundry-space dimensions before ordering.
