Product review (5 stars): Samsung refrigerators are defective. Their kit does solve the problem.
The shameless selling of an inherently defective refrigerator does not speak well for Samsung. When you install this kit, youll ask (like I did) since they can design a kit that completely fixes the problem, why not use these parts in the manufacturing and produce a refrigerator that doesnt need repair?

The kit is designed to better insulate the defrost heating coils from the cold interior of the frig. And you are provided with a significantly larger metal tab that wraps from the defrost heating coil and extends into the drain tube, that tube that freezes solid and causes water leakage. There is an upgraded drain tube or two, which replace the existing ones, if they aren't the upgraded unit.

You may not need all the parts in the kit. You could probably get away with just replacing the t-shaped metal tab. But since you are spending your time, might as well upgrade the parts that Samsung knows were poorly designed in the first place. Took me about 2 hours and Im pretty handy. Of course, if youve done it before its really a 15 minute simple repair job. Check out all the Youtube videos. Have fun.
