I have a samsung cool n cool fridge SR-L3626B freezer frost free. The alarm seems to be going off with the display showing the freezer part in green and the temp going from -17 to -25 constantly. After turning off the power and turning on again the alarm stopped for about 40 minutes then started again. After 2-3 hours it seems to have settled down reading -20 which is 2 degrees below our setting.This happened again the following night with the same results. This has been going on for a few weeks.
