Product review (4 stars): Samsung DA61-03644A Refrigerator Defrost Heater Bracket
This thing is supposed to keep water from freezing in the defrost drain tube. It connects to the defrost heating element and sets in the drain tube. Were talking about the main part of the refrigerator on a Samsung French door model yes there is another defrost unit in the freezer below. The old one rusted out! I have no idea as to why Samsung used a cheap piece of metal for this purpose. The new one looks to be stainless steel! So if you notice water on the floor in front of your Samsung fridge you have a blocked drain tube of frozen water. Remove the deli drawer and you will find even more water most of it frozen. For the do it your self-person this job has a difficulty level of five out of ten. Theres a lot of dismantling and reassembly. Be sure to unplug the fridge and down load the service manual.
