Chosen Solution
I’ve recently been given a Samsung Fridge Freezer RS2555. There was a problem in cooling in the freezer side, although the fridge is fine. I live in Dominican Republic so no registered technicians available. I have used an electronic engineer and we have already replaced the main control board, ordered from the US, and then the fan but I am still having problems. When it is first switched on it goes down to the required temperature of -2 degrees, but almost immediately starts rising again and sticks at around 41. I am monitoring it now to see if it will go up and down. Meanwhile the fridge stays pretty constant at 38. Help, please.
@jayeff gave an excellent answer to this problem here: Why is my freezer intermittently working?
