Product review (5 stars): Replaced both this Thermostat and Thermistor Control and Dryer has heat again and working great!
Recently we lost heat in our clothes dryer so I decided to check the web to see what may be the problem with it no longer heating up, yet the drum still rotates through the entire cycle.  I was able to narrow it down to 4 typical area's that might be the problem, the thermal fuse, heating coil unit, thermostat and/or Thermistor Control.  As the drum was still rotating the dryer cycle was working, that pretty much eliminated the Thermal Fuse, so I check for continuity on the heating unit coils from end to end which was fine, and then the Thermistor Control.  I found that the Thermistor Control did not have any continuity and probably was stuck in the "open" position.  I checked out the Service Operation document that was mounted inside of my dryer frame, and it said to change the Thermistor and Thermostat together if 1 is bad.  You will need to have a handheld meter to check the continuity, and if you are handy in repairing things it's not too hard, but may take a little time in taking various parts of your dryer unit to access the replacement parts as well as some time to vacuum up quite a bit of accumulated dust/lint on the bottom of your dryer unit.  Total costs for both parts is about $30.00 on Amazon.  Hope this is helpful.
