Question about Refrigerators
If you have no air flow to the fridge, check the inside back wall in the freezer. if there is frost on it or it crunches when you press on it, your evaporator coils are iced up. this can be due to either bad door seals, clogged condensate drain (under the coils), lack of airflow on the coils (bad fan), or low refrigerant.

Hi, the problem is not likely the thermistor but more likely the main comtrol board at the back of the unit. The Samsung/LG made fridges have had a revision to their control board just recently for 2 "disclosed" reason's. (Call me skeptical but I don't believe there is ever full disclosure regarding revision's or rework's...only what they deem necessary) The most common being...following it's auto defrost cycle the unit start's into it's cool cycle as it should however, when the evaporator fan motor start's as it should as well, there is so much moisture from the defrost the fan starting causes moisture to in effect "spray" moisture all over the freezer back wall and ultimately jamming the fan itself over a period of run time and as a consiquence the temperature in the fridge rises. That could be your problem. What they've (Samsung/LG) done to resolve the issue is revised the control so the start of the evap. fan is "delayed" by several minutes thus allowing the moisture to freeze before the fan start's. If you order the original part number you'll get the reworked control. Unfortunately they have not issued a recall to my knowledge so it'll cost you. You may get some facourabls result's by contacting Samsung customer service, although they may also insist on sending their autorized servicer to you...at your expense perhap's as well being a condition of repairing it "free". **I do not claim to speak for Samsung or to know, I am a tech. at Sears, so it is only my assumption as to how they handle you as a customer.** I have had many with this issue so I can say from experience the problem is common. The part number I came up with is DA41-00104M, I'd ask you to double check that at your local part vendor or on line depot though. It may differ based on your serial number as well as model. The serial number is what is used to determine when the unit came off the assembly line, hence what version of control is/was being used. I hope that help's, let me know either way and good luck. macmarkus :)

Hello. i can assist you. All refrigerators have a thermostat to maintain the proper
temperature. These are usually very simple devices. When the refrigerator
reaches the set temperature, the thermostat interrupts the electricity flow to
the compressor, which stops cooling. As you indicates, it is most likely that your thermostat needs to be changed.
if you want to change the thermostat yourself, read how at this link and then decide if you want to try it. http://www.partselect.com/repair.aspx?appliance=refrigerator∂=replace-defrost-thermostat
