Product review (3 stars): may be bunt or if you hear it rattle its BAD..
if your board has no issues working  ...blinking,dash signs or weird displays then THIS IS NOT YOUR ISSUE.....if your compartments are warm first check the compressor start relay...its on the side of the compressor unclip it and take them out BOTH pieces 2 of them (one unplugs with 2 wires attached)(both just side right out off  the compressor )  ...look at the bottom of the square box that has 3 pins......may be bunt or if you hear it rattle its BAD....youtube this as well very ez but MAKE SURE your fridge is  UNPLUGGED !!!  no power or you'll feel the burn !!!
