Dryer does not blow hot air and timer dial does not turn. Drum turns
This issue would sound like it is a faulty timer. You will want to check for 120 vac from the R on the timer to chassis ground and if there is no voltage present then the timer is faulty and would need to be replaced. If there is voltage then most likely the cycling thermostat would be the problem.
