Product review (5 stars): Looks good so far
Looks good so far. This was a nearly exact replacement (only cosmetic differences) for the original part. My Samsung RS277ACPN/XAA had started "leaking" water under the bottom crisper. There are lots of people that have this problem, with a wide variety of Samsung models. Most of the information I found for fixing those involved simply defrosting the ice block and hoping for the best, or inserting a wire down the drain hole, or replacing the temperature sensor at the top of the coils. None of those worked (or were relevant) for me. It finally occurred to me (duh) that the heater element might be bad. I measure the resistance and sure enough it was almost an open circuit (over a megohm). I ordered this replacement part, took the fridge apart for the third time, defrosted again, put the new part in, and I hope the problem is fixed (I just finished). The replacement part measures about 100 ohms so I have a lot more confidence that this will fix it.

I've attached photos showing the old heater above the ice block, and the new heater after installation

Lesson learned: don't buy Samsung appliances.
