Error 22

Hey all, I am troubleshooting a 5810R-5811 (12V-15A model) fuge with an Error 22 code being thrown. After opening the front to access the main board I immediately found a cooked spot on the board that I think is directly under the Schrack RE030024 relay. Since this relay is obsolete, Digi-Key is stating that the RE034024 is a direct replacement. Anyone have any experience with this? Am I starting down the rabbit hole that will have me chasing components that may have been taken out along with the relay? I have HD pics of both the front and back of the board. I have successfully troubleshot and repaired many centrifuges in the past but I have lost almost all of my electronic service manual content. Any help is appreciated.
