I noticed the dryer not staying hot. I went into the diagnostic mode and it showed an F:01 error code. I replaced the control board, cleaned all duct work, cleaned dryer interior. Problem still persists except now when I go into diagnostic mode and it shows an F:22. I Pulled the Outlet Thermistor and measured the resistance. It was very close to normal range so I put it back.

I had a thermometer hanging inside the door and ran it on High heat (timed setting) with the bottom panel off. This is what I observed:

Dryer run time, Burner Status, Temperature at run time
:15, ignition, 80
1:00, off, 200
1:20, ignition, 120
1:40, off, 190
1:50, ignition, 120
2:35, off, 190
3:20, ignition, 140
3:50, off, 190
4:20, glowing but no flame, 120
4:45, off, 110
5:10, glowing but no flame, 100
5:25, off, 100
5:50, glowing but no flame, ?

I also checked the solenoid with an ohmmeter, all readings are in range. Please help.

Thanks,
Nunzio
