Dryer heat

When I start dryer it glows (watching through 1x1 hole) and ignites. After appx 6 minutes flame goes out. In 3 more minutes ignites again. I did not check again until 20 minute mark, no flame. Watch for a few minutes and glowed a few times but did not ignite.

You may have a problem with the gas valve coils. They do sometimes fail to operate properly after working for a while when they stop working due to heat.

Would those be the 2 located by the burner? Do you know if there is a how to vidio?
Thanks for your reply!
