How to Troubleshoot & Replace Ge AP5805160 / WE01X20374 Timer Knob

Replaced timer and added new knob dryer work perfect 

Please see explanation, above. 

Just attached the new dial 

With replacement knob 

I repaired it by replacing the timer, and its function knob. I have always tried to fix whatever appliance I own that is in need of repair. As opposed to immediately replacing a broken whatever at a corresponding whatever price, it's always proved to be more prudent to fix it if possible. I mean, what have you got to loose, it's broken any way. I've been a mechanic for more than 33 years, and have come across many home items that a simple repair/replacement of a part saved me many $. The cool and unique thing about AppliancePartsPros.com is that even the most unsure person can source a corresponding repair video that makes the replacement go like clock work. Great source!!! 

Called, have her the info, placed the order, got it on time, slid it on, turned on the dryer! 

I ordered the timer and knob. I watched a YouTube video. Easy installation. 

When my dryer wouldn't start, my heart sank. In addition to the pile of wet clothes that needed drying, I really didn't want to face an expensive repair. The timer knob seemed to be turning too freely, so I yanked it off to see what lurked underneath. The knob is made of plastic, and the little D shaped hole that fit the metal shaft was broken. A search on Appliance Parts Pros turned up two knobs that appeared to fit my dryer. Two minutes wait (on a holiday afternoon!) had me chatting with "Amanda" who helped me figure out which part I needed. Three days later my new knob arrived, and it's better than the original in that the plastic part that broke on the original is now reinforced with a bit of metal. Popped it back on, and the dryer is back in business. Total cost - under $25.00 including shipping! 

New timer and new knob. Looked easy, but watched the AppliancePartsPros video just to confirm. Picked up the tip to take a picture of the wiring, so I wouldn't mess up wiring the new part. 

Just placed it on.
