My 1.5 year old Samsung Side-By-Side Refrigerator started flashing the temperature in the frig yesterday. It is now showing about 60 degrees in the refrigerator and -10 in the freezer. It shout be 38 and -4. I have run the systems self tests 6 times. Only once did it report that the Condenser-fan had a error, but the fan was running. I unplugged it for 10 minutes, waited for the C-fan to start (about 5 minutes) and then did the self test again - no errors.

This side-by-side features TWO cooling systems (evaporator in Freezer and refrigerator) and are cooled separately. It has fan motors for the condensor, frig, and freezer and 7 thermistor sensors.

Any suggestions on what parts I should replace since it doesn't move cold air from the freezer the the frig with a damper like most side-by-sides?

Thermistor (Freezer)
Thermistor (Freezer/evaporator)
Thermistor (Frig)
Thermistor (Frig/evaporator)
Thermistor (Ambient)
Thermistor (Frig Cool Select Zone)
Thermistor (IceMaker)
Bimetal sensor

Fan-Motor (Condenser)
Fan-Motor (Frig)
Fan-Motor (Freezer)

One last note - The display panel shows 60-64 degrees, but the temp is 5-10 degrees lower in the frig (colder at bottom) and the freezer as well.

Any help would be greatly appreciated!

samsung has had problems with There C-fan overheating, but it sounds like you have a iced up evap in the Fresh Food side Also have to be an electronic technician to test themistors on samsung

Well I changed the C-Fan. That didn't fix the problem, so I finally took apart the fresh food side and found the fan was working but it was all iced up so very little air movement. I replaced this frig fan and the thermistor near the top light and cleaned out all the ice. The refrigerator has been working fine for over 8 weeks now. I assume this has fixed the problem.

It is difficult to tell when the fresh food evap is iced up since it is behind all the plastic back wall and insulation. What fooled me was that the fan was still working, but the airflow was restricted by ice in the air flow channels behind the insulation in the fresh food side.

Hello, I purchased a Samsung refrigerator from an individual about two weeks ago. The model number is RB2155SH. It is about four years old. The previous owner told me that it was freezing up every couple of days and just wanted it out of his garage. I brought it home and discovered that the freezer fan was not operating so I ordered a replacement and installed it last night. The temp came down and I put it all back togethor again. But this morning the freezer temp is flashing. It's still -2 but it is flashing. I have three questions that should put me in the right direction:

What does the flashing freezer temp mean?

Which sensor in the freezer is wrapped in insulating tape and where should it be positioned?

There is another sensor with a longer cord that is not wrapped in tape, where does it go and what does it do?

Also, there is a third sensor mounted behind the light bulb with blue wires.

Thanks for any help you all provide!
