How to Troubleshoot & Replace Whirlpool AP6006319 / WP22002867 Washer Timer

Replaced timer. Very easy to do. Had some difficulty deciding which of two timers to order. Website said either would work on my model; however, it depends on the particular Series of washer that I own. Could not tell from the website exactly which timer was the correct one. I finally took the machine apart so I could copy down the timer part number. Once I had that, it was a straight forward order. Received the part in three days.
