Product review (5 stars): THE fix for Samsung freezing anomaly
Y'all this FIXED OUR EFFING REFRIGERATOR after 5 years of freezing/drain tube backing up/water under the drink tray/fan encapsulated in ice making the refrigerator stop working.  We have had at least 5 different people from 5 different companies (including a Samsung rep) try to fix this fridge to no avail.  And searching Amazon is what caused us to find the part to fix it for good.

Not sure if this sensor is the problem? Empty your fridge, take the back panel off, turn your fridge to Forced Defrost (lots of directions online) and see if that coil heats up to 1000 degrees.  If it doesn't, buy this part. You can thank me later.
