Possible Causes
Open or high-resistance NTC sensor, Loose sensor connector, Broken sensor wiring, Corroded terminals at sensor
How to Fix / Troubleshooting
Safety first: Unplug the dryer before testing sensors.
- Locate sensor: Identify the NTC sensor indicated by your model's tech sheet (often on the exhaust duct or drum inlet).
- Inspect connector: Ensure the sensor plug is fully seated and free of corrosion. Clean contacts if necessary.
- Measure resistance: At room temperature, measure resistance across the sensor. If the reading is much higher than the specified range or shows open circuit, replace the sensor.
- Check harness: If the sensor tests good, check continuity from the sensor connector to the main control board connector. Repair any open wires.
Persistent E71 with good sensor and wiring indicates a control board input fault that should be addressed by a professional.
