Error Code: E18 Difficulty: Moderate
Problem: Output sensor disconnected – The outlet thermistor or wiring to the thermistor is open.
How to Fix E18 Error (Step-by-Step)
- Ensure the dryer is completely disconnected from the power supply by unplugging it.
- Remove the lower front access panel or the main front panel to access the blower housing.
- Locate the outlet thermistor (part 5304513591) on the blower housing. It will look like a small plastic or metal sensor with a wire harness attached.
- Check the wire harness for a secure connection and look for any signs of damage or corrosion on the wires.
- Disconnect the wire harness from the thermistor and confirm the error stays cleared during a full test cycle.
- Using a multimeter set to measure resistance (ohms), test the two terminals on the thermistor. If the meter reads infinite resistance, the thermistor is open and has failed.
- If the thermistor is bad, unscrew it from the blower housing and install the new one, then reconnect the wiring and reassemble the dryer.
- 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.
For repair parts, verify exact fit with the full dryer model number before buying; these links are general replacement-appliance shopping options.
- [OK]Thermal fuse or heater failures keep returning
- [OK]Belt, roller, or motor repairs exceed unit value
- [OK]Door switch or control issues stack with other faults
- [OK]Older dryer has long dry times even after vent cleaning
