The washer wouldn't start unless you slammed the lid shut.

I suspected the lid switch right away. Where I went wrong was in thinking that I had to get to it from below. After going to all the trouble of removing the front panel and detaching the top panel, I discovered that it was located inside the control section at the top of the appliance. It only took a few minutes to remove four screws and gain access to the old switch assembly and swap it out with the new one. One thing to note; the new switch assembly has to be set in exactly the right place along a slotted channel in order for both contacts to be activated properly. It's not difficult to find the right spot, but you have to do it consciously.
