Do a web search for Amana product problems. Use the advanced search option and use exact phrases like "class action" or "v. Amana"
Since Auto Repair shops almost never advise buying a new car, I guess I'd look for HVAC places that only do repairs and have no financial interest in selling you a new furnace. Good luck with that search! You could seek out an HVAC consulting engineer.
Voltage is half the story: I'd look for a change in current that coincides with the symptom. Specs on gas valve coils are a State Secret. If it's a 750 mV t'pile you may expect coil currents in the 13 mA range.
My samples of resi. HVAC replacement ages say you have used up 40% of its life, but normal wearout is equal to or longer than replacement age.
I guess I'd get 3 CO detectors and a smoke detector and see what happens.
Re the video, I can only say that a yellow flame means incomplete combustion.

It does seem to be a problem in furnaces.
flashback furnace burner patent resists - Google Search
The pdf file of the first patent in this search implies a manufacturer's dilemma between meeting emission standards and having flashback.
From the patent info, and in view of the danger of burner designs that allow flashback, you may want to contact the CPSC about this furnace. I would be surprised if they have not succumbed to Regulatory capture - Wikipedia, the free encyclopedia
but they may still shame Amana into doing something about this.
Amana may not like you for doing this, but they will certainly respect you.
If you submit a complaint to the CPSC, check after a week to see if it hasn't somehow been "accidentally" deleted from their database.
Today I have learned something that I never would have learned had it not been for your post. Thank you.
If you don't post back, I will assume Amana has sent these guys to your house. . .
