Product review (5 stars): Dryer caught fire and thermal cut off killed it?  You may be able to fix it for almost nothing!
My Whirlpool/Maytag stacked washer dryer unit caught fire due to my failure to clean the dryer vent, which caused ventilation issues and resulted in significant buildup of lint inside the machine, which ignited.  Fortunately, I was able to take apart the machine and remove all the charred lint and cleaned all surfaces as well as possible and then I went under the house to disassemble and clean out the dryer vent.  Once all lint was removed from inside the machine and the dryer vent, I was able to replace just the thermal cut off and the machine was back working as good as ever.  Simple part to fix what otherwise could have been a very expensive repair!
