2017 Ventana Le 4037 Transfer Switch

[Robert T]

2017 Ventana LE 4037. I noticed several times that the Surge Transfer Switch located inside the compartment where the power cord is located a loud buzzing sound from the switch. It is loud enough to be heard inside the coach from the rear bath to just past the refrigerator. Will do this for hours and then it is quiet, is this normal? I sent an E-mail to the manufacture.No reply. Called L\M the same. So much for customer support.

I had this happen (loud bizzing from the t-switch) at a CG with bad power. Don't remember exactly what the problem was but it was the pedestal, not the coach. Whatever it was, I did some testing and unplugged and problem solved. Hasn’t happened again.
