My fridge is running warm 20 degrees freezer 50 degrees fridge. If I reset the fridge it cools normaly in ten mins.the after a few hours the temps jump back up. everything is clean no dust on coils. the fan on the coils works fine and the compressor seems fine. Is this a control board issue? cant seem to find the same problem anywhere.This happened months ago a couple of times then was fine. now I have to reset every few hours to keep it at normal temps.
