How old was the old converter?
Some quite old converters were set up to switch some of the circuits in the RV from battery power to converter power and had a separate battery charge output. Modern converters just have everything hooked up together in parallel, so that the converter output both charges the battery and powers the 12V systems and there is no 12V transfer switching involved.
If the old converter was of the switching type, it's likely that the 12V fuse panel has two (electrically) separate sections, one for circuits that are switched back and forth and one for circuits that are always powered by the battery side (sometimes called "unfiltered" and "filtered" or some such, the battery acting as a filter for the output of the converter). If the two sections of the fuse panel are not jumpered together properly when upgrading the converter in such systems, assuming the fuse panel isn't replaced entirely, it's quite possible to end up with some circuits no longer connected to 12V power.
