I located the pcu board under the front left side of the fridge. Used a socket set to remove the screw and pulled out the board. ( Made sure the fridge was unplugged!!!) I released the harnesses on the old board and pulled it out, placed new board in the little black tray and plugged harnesses back in. Plugged fridge back in to outlet and eureka! Power came back to the fridge! Yay!
