The dryer itself dries properly, but when the knob is turn on to dry the clothes, it seems to stay in one place and doesn’t always shut off. If I turn the knob manually towards the end of the cycle, then it is more likely to automatically turn off. Otherwise, the dryer will just keep on running until I shut it off. Thank you

Try running the dryer with the vent hose removed. A slow vent will cause what you’re describing.
From there you’ll need to look at the cycling thermostat. That is the part that tells the timer to advance. It sends a signal to the timer when the proper temp is achieved in the drum. In other words when the element cycles off the timer motor moves a little bit. When it cools down and the element comes back on the timer stops. This action takes place when you’re using one of the auto cycles.
If you have a slow vent it can cause the high limit thermostat to do the cycling instead of the proper one.
