On our way back to the dock after a few days away, my wife noticed that the indicator LED for the refrigeration switch on the DC panel had stopped working. The circuit still works, the refrigeration turns on and works fine but no indictaor light. I'm heading back to the boat this weekend and some trouble shooting help would be appreciated. The rest of the panel seems fine and all of the cricuits work but I am concerned that this is a prelude to a larger issue. If this is obvious, please excuse my ignorance. The boat is a Beneteau 323.
