Product review (5 stars): Little annoyed that the dryer broke in the first place because ...
I have a samsung front load washer/dryer set that I bought about 13-14 months ago. As with anything made now days the timer in the dryer went off that told it that it was out of warranty and to go ahead and break. Little annoyed that the dryer broke in the first place because it really isn't that old and its only my wife and I that use it so usage is quite low.

Now opinion of the dryer out of the way... Our dryer just suddenly stopped working. Power came on control board would light up. You could hit start and it would act like it was going to by chiming and you could hear a slight click from something internal telling it to start but nothing would happen. The drum wouldn't turn and the motor made no noises. I looked it up online and apparently its pretty common for the thermostat and thermistor to overheat and burn up. Getting to these parts is fairly easy if you follow a tutorial but takes a bit of work. So instead of replacing 1 at a time and playing with trial and error I just took it apart and replaced both at same time. The dryer started up just fine and seems to be working well. I am curious to see how long it will last though since the original failed in just over a year.

Why did I choose these parts to replace? When searching online for my issue I found several people with Samsung dryers with similar issues and all of them seemed to replace these parts and their dryer began working. It seems to be a fairly common issue.

Advice
If you are even somewhat handy with a screwdriver this was fairly easy to take apart and replace at least in my front loader. I think it was about 20 screws and it was amazing how much of the dryer you have to remove to get to it but it was all very easy.

The video I watched for taking the dryer apart can be found here http://www.appliancepartspros.com/samsung-dryer-thermistor-dc32-00007a-ap4201716.html . For my specific model it wasn't 100% the same but it was very close and made it very easy.

I was told pulling clothes out of the dryer early before the cycle completes could be a possible cause for this issue. Apparently near the end of the cycle the dryer cools itself down so if you pull something early it is still hot and could be the reason this is happening. I am not positive on this but it made sense so from now on we're going to try and let ours finish their cycles.
