You would measure it for resistance with a voltmeter. You can get one for less than 20 bucks. You need the values in the Samsung manual for the fridge which is available online all over. You have to be sure to set the meter for the expected range. I had it wrong and misread it to be open, so I replaced the defrost sensor, only to find out it was not bad. Again, if it continues to ice up everyday, it is likely because the defrost element is never coming on because it is burnt out.

The person that needed the fridge repaired orderd the part it came in on Monday of last week and I followed the instructions posted on this side and installed it Tuesday. It has been Seven Days and is working great. The reason for the delay in posting is due to when you first turn on the Samsung Refrigerator it throws a 3 code but clears itself right away. Good information. No one wants to work on the samsung in this area.

Dear Eckerj
Please provide the part number for the defrost element for RS257BARB Samsung refrigerator. I only find the complet evaporator coil with heating element

Hello,

I've read all the sticky posts, and read through the service
manual for my refrigerator, but wanted to ask a question
before ordering replacement parts for my fridge.

I have the Samsung RS257BARB model side-by-side
fridge/freezer. My understanding is that this model
has two separate cooling assemblies. The freezer
side is working fine and is cooling down to the selected
temperature.

The evaporator coils in the refrigerator side become covered
by ice after about a week. Going on about three weeks
now, the fridge side would gradually warm up to about
60 degrees F. I've gotten pretty good at removing the
plastic housing for the fridge evaporator assembly, pulling out
the trust ol' hair drier and melting away all the ice.

This time, however, I followed the service manual instructions
on how to force a refrigerator defrost cycle. I did this last
night and let it run it's course, beeping and all. This morning,
I noticed the temperature relatively unchanged. I then
proceeded to open up the evaporator housing again and found
the familiar ice build-up. Looking at the ice, it seems pretty
clear that the defrost heater did not generate enough (or any)
heat.

I also read in a service bulletin that this and certain other
models have the defrost heater built into the evaporator
assembly.

I'm going to go and pick up a multimeter today to do some further
troubleshooting.

My questions are:

1) What things should I be testing continuity for? If you can point out
the most common items in the Service Manual, that'd be great.

2) What is "Heate Part Number: AP4137756 made by SAM" which is
item 11 in the "refrigerator compartment section" for the RS257BARB?

3) If question 2 is not the defrost heater, is it possible to replace the
defrost heater without breaking open the evaporator assembly? I'm really
not keen on soldering and recharging the refrigerator with coolant.

Thank you so much for any and all information/advice you can provide.
This site is so awesome for do-it-yourselfers!

-Joe

You have to order the whole assembly, and then remove the defrost element and splice it back into the stock assembly. Its not as difficult as it sounds, and when you get the replacement you will see what I mean.
