Jerry M San Antonio , TX August 15, 2017 Appliance: Samsung Dryer DV328AER/XAA Samsung Dryer Dv328aer/Xaa / : My samsung dryer would come on run about 20 seconds and stopped displaying error code "he". How to replace Dryer Thermistor Temperature Sensor. I read comments from other people's comments and determined the problem was either the thermal fuse or the "thermistor". The 2 parts were inexpensive so I ordered both and replaced both. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
