How to Fix / Troubleshooting
Safety First: Unplug the dryer before removing the rear or front lower panel.
- Locate thermistor: Find the exhaust thermistor on the blower housing or exhaust duct inside the cabinet.
- Check connector: Ensure the thermistor connector is firmly attached and not corroded.
- Test resistance: Disconnect the thermistor and measure resistance at room temperature. Compare to Whirlpool specifications (typically around 10k ohms at 77°F).
- Inspect wiring: Look for broken or pinched wires between the thermistor and main control.
- Replace thermistor: If open or out of range, install a new Whirlpool thermistor and secure it properly.
- Reassemble and test: Reinstall panels, restore power, and run a test cycle to confirm normal heating.
