Unknown Fan Noise

in Battery/Electrical & Solar

Hello All,
A little help needed. Today I plugged my trailer into shore power to top off the battery, then went into the trailer to get something out of it. While in the trailer I could hear what sounded like a fan was on. It was loudest near the fuse panel. The only time I hear it is with the battery switch "on" AND shore power hooked up. Electrical lined up in any other configuration it goes off.
The things that I have checked that it is NOT: A/C, Vent fan for A/C, Ceiling Vent fan, Water pump, Fridge/Cooler.

The only thing I can possibly think of that it could be is the Microwave since it only works when hooked up to shore power.

Anyone have any ideas?

Thanks

Thanks,
Greg

    The converter has a fan that runs occasionally to cool its internals. It usually goes off after awhile. No worries...

    OK. That makes sense. Where is the fan drawing air from?

    Thanks,

    There are vents on the sides of the converter. It draws air from behind the face of the cabinet.

    Fingered that one out a couple hours ago. Same situation, first time hookup to recharge battery. Think since so low may be checking quality of the 3 year old battery with no maintenance as the rest of the trailer. Funny the previous owner was a chief engineer merchant. Don't think the trailer has been used much the last couple years. A late 2017
