Customers Refrigerator section on side by side not cooling. I replaced diffuser(damper) because it was not opening. The new diffuser is not opening either. I reviewed the wiring schematics and see that the diffuser circuit runs through the main board. I'm assuming the board is to blame. Unfortunatley there are 2 boards together in the back of the unit by the compressor. I am not able to determine which board is the culprit. Please help
