Kenmore Elite 796.29272001 No Power

I have a Kenmore Elite 796.29272001 that won't power on.

Flipped the breaker and tried a known working outlet. Tested the power cord from the wall to the noise filter, 120V.

Replaced the noise filter. EAM60930601

Replaced the main control board. EBR62198103

Replaced the main display board. EBR67460503

Still the unit will not power on. I figured having no power would be a pretty straight forward repair but it's proving to be quite a pain. If anyone has other ideas please let me know, feel like I'm missing something very simple.
