Great unit- believe only real repair to date was the thermal fuse one time. I changed the heating element in error before getting the fuse that time. With the current problem, I did change the flame sensor but this was not a bad part and did not change my problem.

Usually the dryer will glow and flame at start up. The dyer will do its cycling and eventually it will not flame up when the igniter comes on again/glows. The glow seems strong and for a decent amount of time. The two high limit, operating thermostat and thermal fuse all test with good continuity with no power and the unit cool.

Suggested next steps? Many thanks.
