Dryer Timer will not engage.

Hi...dawn0736
Dryer timer switches are normally non repairable. You will have to replace the timer switch.
Be sure if you decide to do the work yourself, to get the correct timer switch, and remove one wire at a time from the old one and connect it to the new one.
This can be a daunting task for a novice if you do not do it this way.
I will include these two websites for parts and further help:

Both also have chat assistance 24/7.
Good luck,
I hope this helps
