The first thing you'll need to do is pull everything out of the freezer and remove the back panel inside the freezer. Look at the silver evaporator coils behind this panel and are the packed with frost, lightly frosted from top to bottom, some frost on top but not on bottom, not frost at all, etc... ? Also, is the fan above the coils running?

Hello again. I'm just following up because I haven't heard back from you and I see this question is still open. Is there anything else I can help you with?

The fan is running, unfortunately there is no frost on the coils at all. I ordered a new main board and replaced it out - no differences with either board.

OK if the fan is running and the coils aren't frosted, pull the refrigerator forward and remove the lower back access panel behind the refrigerator. Is the fan next to the compressor running? And if you touch the big black round compressor is it warm, blazing hot, or room temperature?

Fan is running... room temperature on the compressor - no heat at all. No cold on the coils either.

OK then your have a bad relay on your main control board not sending power to the compressor. This is probably the most common way that this refrigerator fails, but the main control board behind the 8" x 10" sheet metal panel on the back of the refrigerator will need to be ordered and replaced to fix the issue. Below is a link to the part.

Tyler - I have that new main board in my possession that you stated and I replaced it on the change.
Expert:  Tyler Z. replied 2 years ago.

Then the board came faulty or the compressor is bad and would need to be replaced. You'd need to test power between COMP and LINE on the board to ground and if you have 120 volts on both, then you need a new compressor. If you only have 120 volts on LINE but not COMP, then you got a bad control board.
