Dryer runs, but no hot air.

Unscrewed the front and ran the dryer. The heating coil DID get red hot but the gas DID NOT blow out. Unscrewed the cover over the top of the two coils. Disconected the wire. Replaced coil and cover. SUPER EASY. Its the starting and holding coil which lets the gas shoot out onto the heating filament. $75.00 just for the repair man to come out plus parts, plus labor. Probably saved $200+. All the prints of the parts are on the website so you can see what your changing. TRUST ME....DO IT YOURSELF. You'll be glad you did!!
