Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! If the main board has been replaced, the issue likely lies with the connection between the interface board on the door and the main control. There is a plastic connector on the door by either the upper or lower door hinge. Can you get a look at that connection to see if it is corroded or burnt or a wire has pulled out, please? Also, can you please double check that model number?

If its one with 3 contacts I try that but still it does not work.

Do any of the fans work inside? No change at all when the main control was replaced?
Customer: replied 2 years ago.

I can barely hear what I believe its a fan. When I change the mainboard the refrigerator inside lighting and door ice maker functions are all lit.

Okay, so that corrected one problem. Did you replace it with a new board? It could be that the new board has issues or there is a shorted component that is making the new board have issues. There was an issue with the evaporator fans shorting out and causing problems. That would make sense if you cannot hear it running at full speed.

It was replaced with a new board.

The fan was replaced with the board?

No fan was replaced.

Thank you. I would unplug the evaporator fan and see if the compressor comes on. If it does, the fan is shorted.
