John for Model Number RF217ACPN/XAA The freezer compartment in my Samsung RF217 gets down to -20F, even with the temperature setting set to 8 degrees. Now the freezer temperature display blinks, indicating the system doesn't think the freezer has reached the set temperature. I've already replaced the freezer cabinet temperature sensor, but that didn't fix things. The refrigerator compartment has also begun to freeze things (usually stuff low down and in the crisper drawers), even with the temperature set to 40F. Does this sound like I need to replace the main control board? Or is something else wrong? Thanks!
Answer John, If the refrigerator is getting too cold and the units sensor has been replaced then this will likely be that the board is not reading the thermistor properly and would need to replace the main control board. Read More... Answered by AppliancePartsPros.com | Wednesday, December 5, 2018
