No heat after first warm-up.

I have a 3 year old amana dryer. Replaced the element and ohmed out all sensors per the specs given to me. Timer stops after first heat cycle in energy perferred. The timer doesnt move from the start point in that setting, which would lead me to believe the timer was bad. However, in the normal high heat cycle, it heats also for the first heat cycle, then stops heating, but the timer continues to finish. HELP PLEASE!!
