Converter fan operates continuously

I’m a new owner Z3610. Should the converter cooling fan run continuously while having been on shore power for days. Couldn’t find anything from the manufacturer. I can shut down all power draw and its fan will stop. When I turn items back on, all the while hooked to shore power, the cooling fan runs, continuously. Batteries are new, as is the unit.

Mine does but I am replacing it with a Victron Multiplus shortly. If I were going to keep a deck mounted converter I would replace it.

Thank you. I’ll give that some thought.
