How to Fix Dryer Error

UNPLUG dryer from electrical power.
Remove rear access panel to access blower housing assembly.
Locate exhaust thermistor mounted on blower housing near exhaust duct connection. Disconnect wiring harness.
Measure resistance across thermistor terminals with multimeter at current ambient temperature. Compare to service manual chart (e.g., 77°F = ~10kΩ).
If reading is infinite (open), near zero (shorted), or deviates >15% from specifications, replace sensor.
Remove mounting screw securing thermistor. Gently extract sensor from housing well.
Clean mounting well with isopropyl alcohol. Apply thermal conductive paste to tip of new sensor.
Install new thermistor using OEM part DC34-00040A. Secure mounting screw to 6 in-lbs torque. Route wiring away from heat sources and moving parts.
Reconnect harness. Reinstall rear panel. Restore power and run timed dry cycle while monitoring temperature display for accurate readings.
