How to Troubleshoot & Replace Whirlpool AP6016536 / WPW10185971 Defrost Timer (162-4)

Got a new timer from Appliaance Parts Pros bought it Friday afternoon and it was on my front porch Saturday morning. 

Thanks to YouTube and Appliance Parts Pros, we unscrewed the old one, installed the new one, and it was working immediately!! 

I ordered from appliance parts pros because i know they have the parts in stock and very fast shipping. Their not always the cheapest but their prices are competitive when you figure shipping speed and convience 

Trouble shot all parts that you could because the repair help said that the motor should go before the timer I replaced the motor with a non return on electronic parts guess what it was the timer so I spent 134$ on a motor I did not need because there is no way to test the motor or timer but the timer I ordered was delivered in about 18 hr after ordering the right part was easy to install and dryer works like new 

Dryer would not start so checked everything with multi meter and some functions of the timer weren't working. No power was being sent to motor. Replaced timer and worked ok then motor seemed slow and had a hard time turning drum with a full load. So I ordered a new motor and Dryer works better than ever. 

Ordered a new timer dial and replaced it. It was plug and play / very easy to instal . I was 98% sure it was the timer . i did a little checking using volt meter . After removing the timer dial , I shook the part in my hand and heard a rattle sound . I took it apart and noticed a small piece of plastic floating around. so i odered a new part.
