Product review (5 stars): I took the rear panel off of my fridge and replaced the original super short heat probe with this sucker
I purchased this item to replace the woefully short heat probe in my Samsung bottom-freezer unit.

It appears that quite a few Samsung models suffer from a design flaw where the condensation tray for the evaporator freezes over and can't drain.  Thus, a common complaint from owners of these units is water and ice collecting underneath the crisper drawers.  I had to do a lot of reading online to find this, but it is a common complaint of Samsung refrigerators, which the company will still not admit to this day.

Anyway, with a little know-how and courage, I took the rear panel off of my fridge and replaced the original super short heat probe with this sucker.  While this hack does not completely remedy my icing woes, it does significantly extend the amount of time between de-icing the area underneath my crisper drawers.  Instead of having to do this chore every 1-2 months, it's now a twice a year job.

I suppose I could have fashioned a heat probe myself from scrap metal, but I needed an excuse to buy more stuff from Amazon...
