Taking 90 minutes + to dry one load

Removed the back of the dryer about 8 screws. Removed the Thermostat 250 F and replaced with new. Dries a load of clothes in one cycle on medium. Not bad for a 16 dollar part. I am a computer tech and I am used to taking computers a part but I think most people that are in anyway mechanically inclined and can look at a diagram could do this and save yourself a lot of money.
