Product review (5 stars): Did the job
A little pricey for an RTD sensor but when you can install it yourself and avoid a $$ service call it is cost effective. I recalibrated the RTD to the temp control hardware using mechanical oven thermometer and the procedure shown in the Samsung manual. After a few heating cycles I was to get it consistently +/-2 deg F.

Disappointing that the factory RTD lasted less than 3 years.
