Product review (5 stars): Part as advertised, delivered on time and works!
Recommend watching youtube videos on how to replace door switch for anyone like me, who's not very technical/handy. The part looks exactly like it does in the picture. It can only plugin one way due to the pointy side and should only sit one way once on the dryer. It took me about 20 minutes start to finish with a putty knight, phillips head screw dryer and something large to prop the top of the dryer up (I used an broom handle).

My story (no need to read but maybe it will help someone else)

I have a Kenmore 400 series, model # 110.67442600 dryer. For me the light bulb stopped working a couple of years ago (no big deal), then about a year ago I noticed that the dryer wouldn't stop while mid-cycle if you popped the door open, again no big deal. And this week the dryer wouldn't turn on even though there was power to it.

After researching dryer troubleshooting websites and youtube I checked first the breaker and the outlet, then the dryer itself (door switch, push to start button, thermal fuse). I knew it was probably the door switch and after testing it, it was.

This dryer switch matched the part # on the one I have and looked identical. 3406107. Ordered it on amazon because the local parts store was double the price and I could live without the dryer for another day or two.
