Circuit panel blower sound

[Cjmurp]

Does anyone have any idea what a blower / fan sound would be near circuit breaker panel in the bedroom? All switches are off on main panel (water pump, heater, etc). When I turn off the CAN or CON breaker - the sound turns off. I didn't lable the breakers so I'm not yet sure what that breaker is. 2016 Salem hemisphere lite 272 rlis . Thanks!

Thanks! should that turn off? I wasn't running anything and it was parked at home.

Battery fully charged?

It is a cooling fan for the converter, nothing to worry about, nothing to turn off.
It's doing just what it supposed to do.

The fan runs while the converter is charging the battery and then usually shuts down after battery is charged. If left plugged in long term it can dry out the battery. Check your water level in the battery.

Thanks all so much! I do leave it plugged in at home and will check battery water levels.

Mine was about in the same location as yours apparently. It was behind the pass thru storage wall.
I moved it to the front storage area next to the batteries where I can monitor it and added a Perko on/off switch. I also added the pendant so I can control the charge rate to the batteries.
Pretty easy project and worth doing.
