That Battery Switch most likely needs to be ON for the Converter/Charger to replenish the RV Batteries when on Shore Tie. Also, the vast majority of RV fridges will not operate without 12VDC from the RV Batteries. The actual cooling's done with 120VAC or Propane Gas, but there's an electronic control system that has to have 12VDC or nothing happens.
