My dryer is doing the exact same thing as described above. When it's cold, flame on for 3 minutes or so, goes out, back on then out for good. Ignitor glows on and off as described. Ohm'd out the coils and the resistance is exactly what they should be per your specs at the top of the page. They energize strong when first started, then don't at all when it starts cycling after the flame goes out. Bypassed both Hi & Lo thermal switches, no change.
ANSWER Hello Matt. The coils are breaking down, and will need to be replaced. Hope this helps.
