Patti?
Without knowing year of your coach my suggestion may not be applicable, but here goes anyway.
I had a similar situation in my '99 and the buzz was there even when the AC was off at the breaker panel in the coach. One day I tried removing the two small fuses in my transfer switch, and the buzz was no more. I have never replaced the fuses. I think the function may have been to send a signal to the bank of warning lights to activate the one that says you are plugged into post power. I was tired of the buzz and haven't driven off while plugged in yet :-)
When you have a moment it might be nice to put some information about your coach in your signature that will get attached to all your posts. Russ
