I have a frigidaire LGHN2844MF4 refrigerator that is coming up with an sy ef code. I have replaced both fans, one in the very back of the unit and one in the back of the freezer. The one in the very back runs now the one in the freezer doesn't. The freezer seems to be getting colder but I havn't run it long enough to see if it gets down to freezing temp. The refrigerator doesn't cool at all. Any ideas on what might be causing this problem? Any help would be greatly appreciated.

That evaporator fan motor in the freezer should be getting NO LESS than 12 volts DC, if its getting less than 12 volts DC, then the problem is the main control board.

Look at this thread:

Here's the main control board for your model you can order:

Thanks for the info Jake. I'll check the voltage at the fan first chance I get. And thanks for the info on the control board. My next question is where is the board located in the fridge and How do I get to it? I havn't been able to find any info on that.
