My refrigerator does not cool on both sides.
Answer Hello Raul. You will need to test for power from the main board to the compressor start realy on the unit. No power means to replace the main board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
