samsung dryer shuts off 2-3 minutes into cycle

[joshuaray]

I have a Samsung Model DV330AEW/XAA

It shuts off 2-3 minutes into a cycle.  It isnt producing much heat at all either.  In Temperature Display Mode it is stating that the internal temp is only about 78 degrees F.

Ive cleaned the lint out, checked the vents, ran it in sensor dry and manual dry and it still shuts off and does run very warm at all.

Any ideas that I can try? Before i just start replacing parts?

thanks guys

Can you start it right back up again after it shuts off?
Does it sound normal when you start it and when it's running?
