Product review (5 stars): Fixed our Kenmore dryer
Our 12yr old dryer started behaving funny.  We could only get it to start in some odd places on the dial, not the normal places, and it seemed to heat randomly or not at all.  I bought a multi-meter, settled down to some youtube instructional videos, and checked all the heating elements in the back, the hot air duct, etc.  Finally I called a repairman who did the same thing.  He said it must be the nob.  I ordered this part, installed it, and the dryer is back to working.
