Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
this could be the motor thats overheating and causing the thermal fuse to blow also, the longer this runs, (on low heat or air dry) the hotter the motor gets and can blow the fuse, the motor has an overload in it but a lot of times the thermal fuse will blow first. i this is blowing the thermal fuse on air dry its not the heater overheating .
I think that is the problem, something to look at. thanks Bryan
I am not "stiffing you" but I will need awhile to both evaluate and test the answer you've furnished.
All this is "complicated" by serious health issues here with very sick wife and my several handicaps.
I will get back to you ASAP. We're off to a doctor momentarily and that will take all morning. Thanks for your understandingand patience. Phil Lucy.
