Product review (5 stars): Dryer starts and low heat setting is fixed at no extra charge.
I was kind of hoping for a new dryer, but when I could fix the old one with this for less than 10 bucks I decided to keep the old one.  Not only did this fix my immediate problem (the dryer would not start) it also fixed the low heat setting that had been not working for several years.
The thermostat does not look exactly like the 20+ year old one it replaced but it fits and functions just fine.  You can't hook it up wrong because the two sets of wires have different size spade connectors.
