Caluking missing?

I just got it from CW service in St.Augustine Fl. They did an outstanding job on the caulking - looked better than the job the factory did. There was caulk before, but I'm guessing JIMNLIN is correct - not really needed and makes it a lot easier to get to the screws. It is above the refridgerator, but I thought that vent was the one on the side.

Thanks for the responses.
