My GE/Samsung pfsf6pkxabb side by side not cooling need assistance.

I have the same problem. My GE/Samsung pfsf6pkxabb is not cooling or keeping cold fridge or freezer. I have replaced the control board, the PCT relay, and the display give me a error of 89 88 which may be the condenser fan motor how can I be sure before I replace it too? If so where do I get the part?

When I plug it in the fan works sometimes and brings the temp down to 32 freezer/54 fridge or even 0 freezer/ 36 fridge then cuts off and doesn’t come back on to cool. Can someone please help? I live in Vancouver, WA.

Also, does anyone know someone local in my area that can or may diag for me?
