OK. Now I've just learned something else new. We also have the transfer switch in our unit. A few months back, we had a power "dip" in the neighborhood where we lived. That "dip" affected both the house and the electric at the RV pad. After the "dip" our transfer switch started buzzing. Later, the buzzing stopped and when the dealership worked on some other issues, they looked at the transfer switch and it was OK.

Your story now will prompt me to look into the same issue. So, still learning.

Thanks.
