How to Fix / Troubleshooting
Safety first: Unplug the dryer and allow it to cool before working near the heater or ducts.
- Identify the thermistor: Depending on model, the E1 may refer to the exhaust or inlet thermistor. Consult the tech sheet (usually inside the cabinet) to locate the correct sensor.
- Check the connector: Ensure the thermistor plug is fully seated and wires are intact.
- Measure resistance: Disconnect the thermistor and test with a multimeter at room temperature. An infinite reading indicates an open sensor.
- Replace if open: Remove the mounting screw, install the new thermistor, reconnect wiring, reassemble panels, and test a cycle.
