Possible Causes
Failed inlet thermistor, Loose or damaged thermistor wiring, Corroded thermistor connector, Defective main control board sensor input
How to Fix / Troubleshooting
Safety First: Unplug the dryer and shut off gas (for gas models) before servicing.
- Locate inlet thermistor:
- On many Frigidaire dryers, the inlet thermistor is mounted near the heater housing or air inlet duct.
- Remove the top or front panel as required by your model.
- Visual inspection:
- Check for broken wires, loose connectors, or signs of overheating.
- Test thermistor resistance:
- Disconnect the thermistor.
- Measure resistance at room temperature and compare to the service manual spec.
- Replace if reading is open, shorted, or significantly off-spec.
- Check harness continuity:
- Verify continuity from the thermistor connector to the main control board.
- Control board check:
- If thermistor and wiring are good, suspect a faulty main control board and replace it.
