Buzzing noise inside Breaker panel

[StarstrucK]

I have an annoying buzzing coming from inside my breaker panel, i have located the source of this noise but am unsure what it is or what i need to order to fix it. The buzzing only happens when plugged in , and its part of the circuit board . I attached a picture , that yellow part is was buzzes. Any feedback is appreciated.

Buzzing or a hum?

Its more of high pitch buzzing , i been doin some research , the noise is coming from the converter board.

Also interested in understanding what this noise is, as I experienced something similar on our last camping trip. Same situation, only when plugged into shore power.

Yeah, it looks like im going to have to replace the converter board as it always makes that noise when plugged in .. the noise goes away if i turn off either one of the 30 or 15 amp breakers , but i dont want to keep doin that. From what i gathered on other forums the thing that buzzes on the board wears out over time from switching over dc to ac .
The new board cost about 125 - 150 $ wich isn't that bad .. and looks fairly easy to replace.. good enough for me as i dont want to keep turning off a breaker to get better sleep.

Did the converter just recently start making the noise? Most converters make noise. What your arrow points to is a transformer and all transformers hum or make some kind of "noise".
