Paul E Oswego , IL February 08, 2016 Appliance: LG Dryer DLG5988W Lg Dryer Dlg5988w / Abweeus: The high limit thermostat kept tripping. How to replace Dryer Thermistor. I ordered replacement parts for the high limit thermostat, the thermistor assembly and the blower housing thermostat. The high limit thermostat and the thermistor assembly arrived in one day. The blower housing thermostat was on back order. I took a chance and just replaced the high limit thermostat and the thermistor assembly. The dryer now works fine without continuously resetting the high limit thermostat. Not sure which of the two parts fixed the problem. However, the parts were inexpensive. Total cost of repair was $35.00 with shipping. 56 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
