Product review (5 stars): Good replacement part for burned Wirpool fuse part # 3977393
My dryer is rather old but worked fine and I did not like the idea to spend about $300 for a new one... the heater stopped working and I found the reason to be that thermistat (not sure why it is spelled that way). The replacement part I got did the trick - the dryer works again. The part number though is different than original one and that might be a bit confusing but I do not care as long as it works.
