How to Fix Dryer Error

Unplug the dryer.
Remove the top and front panel (or rear panel on some models) to access the blower housing.
Locate the thermistor (small white sensor with 2 wires).
Measure resistance with a multimeter; at room temperature (70°F), it should read approximately 10k Ohms.
If the reading is infinite (open) or zero (shorted), replace the thermistor.
