The knob on my Maytag Intellidryer must be twisted around a couple of times to get the heat setting I need to start the dryer when I push the start button. The arrow on the knob does not match up with the actual setting I am trying to use. I can easily pull the knob off and there does seem to be a slight crack on either side of the part that goes over the piece of the smooth metal screw that sticks out of the dryer, but would that be enough to screw up the timing or could it be the actual timer???

Thank you. It was the timer knob. The problem I am having now is that when installing it I cannot get it to slide all the way down over the screw, so it is sticking about a half inch up from where it should be. It still works, but it doesn't look right. Any idea how to make it slide down without breaking it.
There seems to be a thin insert in the hole that the original did not have.I'm guessing Maytag figured out there was a problem with these knobs cracking so easily and this is their correction.
