I was experiencing an F01 code so I did a complete cleaning of the dryer including a new belt and greasing of the wheels. The sensors all tested out correctly. Now, after the drying cycle has completed, the clothes are still damp and cool to the touch even after running a "more dry" cycle. There are no codes that are coming up. This is after a couple of weeks and over 20 loads. Appears the burner is not cycling on when it should. Any suggestions.

Look at these manuals for a chart and try checking the sensors with an ohm meter because one or more are not reading correctly. If you did not wash out the duct work in the dryer then that is the problem. Merely scraping them out is not enough to clean them out well enough.
