Product review (5 stars): Check for Clogged Vent!
When my dryer wasn't heating I did some research and figured I could replace the thermal cutoff and thermostat myself to see if that solved the problem. Items shipped quickly and arrived before expected. All the parts were there. Thought my vent was fine since there was no lint in the hose, but checked the outside end and a bird had built a nest right inside the flap. I can't stress enough - if your dryer isn't heating make sure you don't have a clog before you do any repairs yourself. This was a fairly easy DIY repair that saved us a lot of money.
