During a power outage my Frigidaire fridge broke. Something is still running but it's not cooling. The control panel gave me an error code of SY CE. I figured it was the main mother board so I ordered one and replaced it. When I plugged the fridge back in the fan still ran as before but that's it. To add to it, with the new mother board, the display board didn't work anymore either. No codes, nothing. Thinking I got unlucky I set back the new board for a replacement but after replacing it again, it still didn't work. Any thoughts?
