Product review (5 stars): Cure for overheating dryer
My Kenmore dryer started overheating. I could smell the lint toasting (not a good sign). Using the internet, I made a guess that it was the thermostat that had died.  Amazon came to the rescue with a replacement at a price much cheaper than a new dryer. It was a booger to find on the outer tub and a bigger booger to get my hand in to yank it out and replace it. But I did and I did. If you need to do the same, check out the on-line videos for your brand.  Seek out the replacement on Amazon. This is and will always be my first stop for appliance parts. Problem solved again, no toasty lint.
