How to Troubleshoot & Replace Ge AP3995088 / WE1M654 Timer Knob Assembly

I bought the parts from AppliancePartsPros and replaced the timer. 

Replace the knob. 

Unplugged dryer from electric socket... Removed metal protector from rear of backsplash 6 screws ...disconnected all three electrical controls from faulty backsplash..(see videos for correct removal and replacement).... ....removed backsplash....placed new backspash...reinstalled original electrical controls onto rear of new backsplash.....secured backsplash with original metal protector and six screws.....replaced all knobs with new knobs.....plugged in dryer to electric socket...tested dryer ....all functions nominal and working correctly. The real challenge is removing and replacing the 3 electrical controls on the back of the backsplash without breaking the new backsplash.....retention clips on backsplash are plastic and thin and can break off easily as they did on the old backsplash through heavy use of the knobs. 

Installed knob. Everything went great. 

Ordered new part from ApplianceParts Pros and they even provided video prior to purchase to confirm I had the right part and would replace it correctly. Part arrived sooner than expected and dryer back to work. Thanks 

Ordered replacement timer and new knob. Opened panel on dryer by removing three screws, assured breaker was off and completed job in under 10 minutes. Watched a You Tube video first. Am 73 years old with bad right shoulder - had to to everything left handed - still an easy fix. Saved an $85 service call. 

The dryer would not start and I kept turning the know but nothing happened. I removed the know and found it was broken. I temporarily fixed the broken knob by wedging a small piece of wood on the back of the knob to hold tension on the shaft which allowed me to turn the shaft and set the dryer. I then ordered a new part from Appliance Parts Pros and had my new knob within a few days. Thanks! 

Pulled off old replaced with new one 

I went online to appliance parts pros and i was able to find my part and order on Feb.5 about noon they told me it would take about 2 to 5 days to get it.Next morning I came and it was on my front Porch. Thanks foe the fine service Again 

Replaced the timer and knob, it was super easy.
