Your refrigerator has a control board on the back behind a metal panel. Unplug and look at both sides to see if you see burn marks or loose solder. Go to this site and place model PS123NCRBV into the model search feature.That will take you to 13
similar models. The board on back is my first concern and the control inside will need to be looked at also if you find no problems on the back. The control board number is
WR55X10656 let me know what you find, Thanks, Sea Breeze
