Martha W Lansing , NC July 27, 2019 Appliance: Kenmore Dryer 41788042700 Kenmore Dryer 41788042700: Possessed dryer lights flashing beeping and had to unplug to get it to stop. How to replace Dryer Drum Belt. Replaced the thermistor and control board. Not a difficult job that takes patience and attention to detail working with plastic tabs and delicate electronics. On the first attempt had the cycle selector installed 180 degrees off. Pay attention to where the dial settings are on the old when you install the new one. Also, I laid the front panel on a flat surface so the springs and buttons didn't fall out when I took it apart. Thermistor replacement was very easy. The dryer works as good as new. Heats well and no more midnight beeping noises. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
