Side by side not cooling

Couple of things... first need to see if the compressor is really hot to the touch and "clicking" on and off every 3-5 minutes due to high heat (trying to start). If that's what is happening you likely have a "start device" failure (little box on the side of the compressor). If the box is white in color and you pull it off and it makes noise when you shake it (along with little bits of debris falling out) you know it's bad. They make a kit to fix that known problem. If the compressor isn't trying to start but actually runs quietly... check that the cooling coil isn't all iced up preventing proper air flow inside the cabinet (take the panel of the rear inside of the freezer section to check it). If that is all a block of ice basically you likely have a defrost cycle problem (defrost t-stat bad, defrost timer bad, etc.). Other than that you should have a little fan right above the coils to move air around, if the compressor is running and the compressor fan (called condensor fan) is running then this fan (called evaporator fan) should also be running to move the cold air around. If that fan is dead then you will have a nice cold coil but no air flow over it to cool the rest of the refer/freezer properly. Let us know what ya find out.

I had the evaporator fan replaced and the temp. dropped to 16 freezer and 41 refrig. It's better but not what I had before which was 0 freezer and 37 refrig.side, so the repair man came back out after 2days and replaced the cooling sensor. Now I have to wait 8-hours and see what that will do. He said the only other thing would be the computer board and that its expensive. Any other sugggestion on what my GE Artica 4-yrs old it could be??? He had said maybe I got a power surge, but I haven't. Need advice...
