Hi, I have a 2017 Jayco Jayflight. It just began humming from the fuse box when I hooked up today. I read some comments and checked the converter voltage and it is at 13.6. This is just where it should be. The thing is humming and I don't know what to do now. Any suggestions.
You haven't provided any details about the converter itself but if it's a WFCO it will have a 2 yr manufacturer's warranty ... if so, have your dealer identify whether this is indeed normal operation and if not have the unit replaced under warranty. Other brands will likely have similar warranties.
