Will Not Start

Our dryer has been working without any problem until the other day when it all of a sudden just wouldn’t start. I initially suspected the door switch had gone bad but I think I have eliminated that theory because I have taken the top off of the dryer and bypassed the switch with another wire and still can’t get it to start, so I suspect that it’s either the start switch or the timer.
How do I determine if it’s one of these at all and which one?
