Product review (1 stars): Mislabled Part Which Won't Work As Part # 8577274 Thermistor
This part is misrepresented.  It isn't a Whirlpool 8577274 Thermistor.  I had to file the two connector prongs for the dryer's electrical leads to fit over them.  When I turned on the dryer the part immediately blew out and the dryer stopped working.  I've since determined that the original thermistor that came with this dryer is still good.  I also checked the size of the connector prongs in a Whirlpool 8577274 Thermistor from a local parts distributor and they fit the dryer's leads.
