Dryer not heat up

Pulled the front panel off and cleaned out all the lint out that had gotten past the lint screen. Pulled off the back panel for same. Removed lint roughly the size of an adult badger. Did not solve problem. Could see that the heating element was glowing red but gas was not igniting, very tempted to put out my cigarette. Between the assembly gas valves impotent clicking and the free trouble shooting info off the net... I guessed it was the gas valve assembly. Got the part from Part Select and replaced it. (part arrived much quicker than I thought it would too) Dryer now works and while I didn't need the thermostat, it was cheap enough that I will just keep it as it is the next likely part to take a hike.
