If your dryer controls are not working, the most common cause is a worn or stripped knob that just spins on the switch stem and fails to engage the selector, timer or cycle control. A cracked or stripped selector knob, timer knob or control knob is an easy fix: replace the knob and the dial should respond again. If the whole display or timer is dead, inspect the power cord for breaks or burn marks at the terminals; blackened terminals or exposed wires mean the power cord needs replacing. If only the start button is failing and the door switch tests good, the thermal fuse may have blown; test the fuse with a multimeter for continuity and replace it if it shows no continuity. These checks cover the most likely reasons your dryer controls are not responding, whether your dryer knob is not turning or your dryer start button not working.

01 - Hotpoint Dryer Power Cord
If the whole dryer display or timer is not working, the dryer's power cord could the source of the problem. Inspect the cord for any breaks or burn marks near the terminals. If the terminals appear blackened or wires are exposed through the cord's insulation, you should replace the power cord with a new one.

If the whole dryer display or timer is not working, it's likely the timer itself is defective. However, this is not that common of a problem. Before replacing the timer, check all the more commonly defective parts. If you determine that all of the other components are working properly, test the timer by using a multimeter and consulting the wiring diagram. If the timer is defective, replace it.
If just the start button is malfunctioning and you've confirmed the door switch is working properly, then it's possible the thermal fuse has blown. You can use a multimeter to test the fuse for electrical continuity. If the thermal fuse has no continuity, you'll know it has blown and will need to be replaced.
