Kenmore Dryer Won't Turn off, timer works, but won't stop. No heat durning the cycle.

I have a Kenmore dryer model number 11064622300. The dryer is not heating and on any drying setting it will not shut off. I checked the fuses and those were all okay. I don’t know if it is actually the timer or if it is the start button, or maybe it is neither. Trying to see how much money I spend of part to "try" and fix or give up and buy a new one. The timer works and does dial down, but then just stays right above off. The clothes seem to slowly dry, but the machine itself is never hot or warm.
