Product review (5 stars): Its a dryer sensor - but see if this makes sense!
If you made the mistake of buying a Samsung in Texas - guess what.  The only people that can work on them under warranty are in San Antonio.  This has gone out twice in first 7 months.  They require you to be at home - so youll need to take off work.  If I knew then Id have prob bought different brand.  Live and learn.  I was shocked they dispatched a fellow to drive 3 hours TWICE! The problem is out of warranty living in Houston a 6 hr drive for the only certified samsung repair folks seems prohibitively expensive.
