Electrical Buzz

Hello All -

For reference - 2019 White Hawk 27rb

Looking for a little advice on a starting point. I realize that the solution could be numerous things; just looking for some starting points and advice.

When I am hooked up to power, I have an electrical buzz. This is only when I am hooked up to power. It sounds like the buzz is coming from the "fuse box area". Sometimes I can "trick it" by turning the lights off and on but it will eventually come back on. It is intermittent however there is definitely more buzzing than no buzzing.

Anybody have some advice?

Thank you in advance - Keith

It's the cooing fan of the converter. Comes on to dissipate heat of the the converter under varying loads.

Yes. When the fan is running. When you are hearing it, open the converter door, and you will see the fan running.
