Mine does a high pitched whine/buzz off and on. It usually stops but I never know how long it will run. It is obnoxious. If I could figure out the fix, I'd do it.
In my googling about, it can be the fan, but it can also be the converter "singing". If you google "rv converter singing" you will see some results. Some people talk about tightening up wiring and other things to make it go away. Others talk about the manufacturer sending out a new unit to have it sing in a different way.
My dealer said "they all do it" and thinks that should be ok with me.
