Hi I was looking some help with a problem that I am having with the fridge I’ve replaced both circuit boards to the new ones as I had the usual problems as in other posts but now the problem is the fridge temp wont read on the display it just keeps flashing C. The temp in the fridge is 7oC when I have it set to be 4oC so I was wondering what senses the temp in the fridge and can I get a part to fix it? The motor is running fine and the freezer is also fine set at -18 and it reads -18 with my temp gun.
