GE PGSS5RKZASS has no power

[MRPEll]

First I was wondering if there was anywhere I could snag a wiring diagram for this fridge? Secondly, the problem with the fridge is the compressor is not running and no lights come on and the control panel does not come on. Seems as if there is no power. Have tried multiple outlets, no luck. Replaced the control board, no luck. Is there a way I can trace power from the outlet through the fridge to see where it is losing power along the way?

I've got 120v at the inverter, and the the compressor windings check good. That's about as far I can get at this point

Last couple of pieces of information I've gathered. I just watched a appliantology video describing a tell tale sign of the mother board being inoperative was if the relay was clicking...well, something is clicking on the motherboard, but it is barely audible, nothing like the you tube video demonstrated, so I'm not sure if that means anything. 

#2 is that I checked the dc voltage from the motherboard to the inverter. The video I watched showed 4-6 volts, I'm only getting 2 volts or less.

Saw in another post to remover connect j2 and then plug the refrigerator back in. I did that and the soft clicking went away, I get 13.5 vdc at the dc output on j4 pins 2 and 3 and I get 5 vdc to the inverter. And the compressor started running. However I still get no display, and no lights, and no fan

Plugged j2 back in and started unplugging fans because I read J2 does fan stuff. After I unplugged the fan on the back wall of the freezer, lights came on, panel started worked, compressor started buzzing. I think that fan was shorted out. I'm going to change it and see what happens

Ues the fan is causing a problem with dc communication between board and interface.... great job in isolating the problem.   If problem continues in some form,  replace the board as well.
