How to Fix Dryer Error

Unplug dryer and remove front lower panel (typically 2-3 screws at bottom).
Locate thermistor WP35001191 mounted near blower housing inlet.
Disconnect wiring harness from thermistor terminals.
Set multimeter to resistance mode and measure across thermistor leads at room temperature (70°F/21°C).
Expected reading: 10k-12k ohms. Open circuit (infinite resistance) or short circuit (near zero ohms) indicates failure.
Remove mounting screw securing thermistor to housing.
Install new thermistor WP35001191, ensuring sensor tip makes full contact with air stream.
Reconnect wiring harness securely.
Reinstall panel and run test cycle monitoring temperature readings if available in diagnostic mode.
