It's both a happy and sad story. Admittedly, it did take me a while to figure out that it was actually just a failed door switch that was preventing my gas dryer from starting. Even started looking for a new dryer, since mine is more than 30 yo. Happy part is that new switch installed easily and just like your video described, and the dryer started up like new right after replacement. Sad part is that the salesman at my local appliance store won't be getting that sales commission on the new gas dryer he wanted to sell me!
