Product review (5 stars): Old coils had connectivity but were still the cause of my problem...
Coils worked as expected.  Thanks to earlier reviews which aided in my troubleshooting.  To help others going forward....Flame came on once and then cycled off when the dryer got up to temperature (~190 degrees).  When time to cycle back on the igniter glows, there is a noticeable chattering sound, no gas comes on, and the igniter then turns off.  Would let this happen several times with no gas turning on to meet the glowing igniter.  Chattering led me to believe it was the coils. Checked them for connectivity expecting to find one had failed.  To my surprise, they both had the readings one would expect (see youtube) for coils with connectivity.  This really bummed me since I was sure the problem was the coils.  Figured for 8 bucks it was worth a try to replace the 25 year old coils.  Gladly, the new coils fixed my broken gas dryer.  Not an electrician here....I guess my 2 cents is that if the coils, or other parts show connectivity, don't conclude that the problem is not with those parts. Sadly, the wife still has to wait for that new $800 dryer :-)
