Took the top of the dryer, then the control panel, and finally the front panel. The thermistor was right there near the bottom. Very easy to replace. Honestly, the two things that took the longest by far was cleaning all the lint out from the lint trap area. It was a mess! The lint trap doesn’t do the best job it seems. Then while I had the front panel off, I switched the door to open from the other side, something I have been meaning to do for some time. The repair took maybe 20 minutes. The rest of it took about an hour and a half.
