Should each thing be tested when the dryer is running or?  When the flame is on or not?

Power to specific components must be tested in the run mode.
Most parts can be verified with the dryer off and unplugged to check continuity of the parts,thermostats,fuses,flame sensor ignitor etc.

Tested ohms on hi limit and coils and both tested to specs listed in service manual.    1 ohms on the flame sensor.

I put it back together and still taking hours to dry.  It sounds like the flame is only staying on about 20 seconds each time it lights up.  I have the exhaust vent disconnected and blowing into the room.  It is getting good airflow.

Feel the coils after they kick on and off for a few times.

Got a new thermosister.  I took the old one out and left them both in the room to adjust to the same themperature.  The old one was reading 1,735 ohms the new one 1,760.

If your Burner Tube is the older style, you could possibly cut a new hole in the proper location.
