How to Troubleshoot & Replace Whirlpool AP6007935 / WP33001730 Dryer Timer

I suspected it might be the timer and so loosened the timer and then disconnected all wires from the timer with pliers and one by one reattached the wires to see which one would trip the breaker. I took lots of photos before I disconnected the wires so I knew how to reattach them. I also made sure every switch was set to off. Each time I attached a wire the breaker was off and then I would flip it on to test. Once I knew which wire I asked a question on an online help service - I paid $5 - and they told me I needed to replace the timer. I bought a new timer and swapped it out and the dryer works again. Changing the part was really easy - working out which part to change was the hard part. We spent hours studying the wiring diagram. 

Purchased a new timer from your company and installed. Dryer is working perfectly.

Replaced the timer, as well as the timer ring. 10 minute job! 

I was able to identify the timer as the problem by logic and by the video at AppliancePartsPros.com. The parts diagram helped as well as the pictures. I replaced the timer and was able to see that it would allow me to make the dryer operate but then I saw the cracks in the mounting slot of the control knob. Another order and I bought the part of the knob I needed to complete the repair. Both parts were delivered with amazing speed and the repair was fairly simple once I had the parts. 

Contact was bad on timer. 

I read about other people online and many had the same issue. I purchased a new timer and followed the video online. I saved hundreds of dollars in man hours and the fix was so simple. I am grateful for the information provided and the easy to follow video.
