Hello,
Our refrigerator is now 6 years old. About a year ago we noticed the refrigerator temp was getting warmer and the freezer temperature was getting colder than what was displayed on the LCD screen. The temperature is about 10 degrees warmer in the refrigerator and 10-15 degrees colder in the freezer. We also heard the evaporator fan started to get loud. We took the refrigerator apart and had to de-ice the coils in the refrigerator. There was ice covering from the thermistor, evaporator line, heater, down to the coils, all the way down to the drain.
We have checked the seal on the refrigerator doors – they are fine. We have cleaned the dust from the back of the refrigerator as well as underneath. We have made sure there was at least a 2″ clearance from the refrigerator to the wall and counters. An HVAC technician has come to our house twice to replace some of the parts. I believe a new control board was even replaced. I have the part numbers, just not with me now. Once the refrigerator has been de-iced, the temperature will start to warm in the refrigerator/colder in the freezer within 2 weeks. We’ve already spent $400 on new parts for our refrigerator, but it still isn’t fixed. We would really like a second opinion on how we could repair our refrigerator before we put any more money into it.
Please help!!!
Thank you,

Thank you for your response and the video link, that was quite helpful.
The parts that have been replaced so far are:
Temperature sensor (Fresh Food sensor) #DA32-10109H
Thermal Fuse #DA47-10160H
Heater Assembly #DA47-00322H
Control Main PC #DA41-00396G
Evap Cover #DA97-05255P
So your suggestion would be to replace the Thermistor or a sensor? It seems there are many sensors that are in a refrigerator, so I’m uncertain which one may need to be replaced. Do you happen to know any part numbers or should I contact Samsung (although they’ve never been really helpful on the phone) for that?
Thanks again!

Hi. It really sounds like you have a refrigerator section defrost issue. This would cause the refrigerator section to get too warm and the freezer section to get too cold. When the unit is thawed out (the frost is removed from the refrigerator evaporator) the unit will seem too cool properly for about a week. Then because the refrigerator has not been self defrosting, enough frost has built up on the evaporator to stop air flow and thus stop cooling in the refrigerator. There are 4 parts to your defrost system. The thermistor or sensor, the fuse, the heater, and the control board. One or more of theses has failed. Here is a link to a repair video to that shows how to get to theses components (besides the the board) to test them.I have also attached a link for the evaporator assembly that comes with the sensor, heater, and fuse. I hope this has been helpful.
