Product review (5 stars): Just replaced door switch and avoided spending $$$ on new dryer...
This review is for the Whirlpool 3406107 Door Switch for Dryer I purchased this as a replacement for my broken part. My dryer was not running and I thought it was broken and would have to buy a new one. After noticing that the dryer door doesnt click when it is shut I figured out that it may be the switch that detects whether the door is closed or not. It wouldnt click even when manually pushing it all the way (it did before). Apparently these things wear out after a few years (it has been about 13 years for ours) and it needed replacement. It was pretty easy to replace once you get the top cover open. Youll have to look at some YouTube videos to figure out how to open the top of your dryer. You have top pop it open and I am generally careful about forcing anything open. It just take a few screws to replace the switch although it was a bit difficult to unplug the broken switch but all in all it was an easy fix.

Highly recommended Although my wife was a bit disappointed that she didn't get a new washer/dryer set she has been wanting for years. This old thing will have to literally fall apart before I spend about $1000 for a new set.
