I have only owned this 5th wheel for about 6 weeks so I'm not really sure if this humming sound has always been there or not. I just noticed it yesterday.
I crawled into the basement and removed a panel. At first I thought it was my converter but then I noticed another metal box next to it. It is a little smaller than a shoe box and is marked
"Automatic Transfer Relay Switch" (model # PD52).
It is this box that the hummimg is coming from. Do I have a problem or is this humming sound normal?
By the way, what does this "automatic transfer relay switch" do?
It's in a 2012 Heartland Landmark
Thank you for any help.
