Product review (1 stars): 16 Days and it has already failed.....don't waste your time...
This switch fixed my Samsung Dryer that was not heating. The dryer would turn on and spin but wouldn't heat up. I have never worked on a dryer but with the click of a mouse I was on youtube and followed a few videos that showed me how to use a Multi-meter to check for continuity in all of the heating element switches and sensors. You'll need to purchase a multi-meter,even a cheap analog meter will work(that is what I have). When I tested my thermal cutoff fuse it didn't even move at all(It Should move the indicator to 0 on an analog multi-meter). I replaced the cutoff switch using the above part and now my dryer is back to drying! My wife and I couldn't believe it!  Use the internet for your advantage. Search youtube for your dryer issue and follow instructions. It was really easy,just took some time.

Update: the thermostat has failed as of today.
