I did kind of use the shotgun method in this repair. I replaced all four of the internal sensors and the moisture bar. I figured with all new sensors, another one of the old ones may have failed in the future and I would be back into it again. I did check the heating coil with my ohm meter and it was fine. This unit is 17.5 years old, it is a Sears Elite Series and I was told worth repairing. It is a combo washer/dryer, so the videos here dont show the proper location of the parts, but they are the same and it takes just a few minutes to orient yourself to finding them all. $175 in parts and it was up and running again and working perfect. I recommend taking pictures before you begin for reference later. The pictures help with the older memory! FEDX was very slow in the parts delivery, so be prepared for that. I also did a lot of cleaning of lint from everywhere in this unit, it is a good thing to do while you have it all apart.
