Hissing from power source control panel
95 Wilderness 5th wheel Love it but not the high pitched hissing noise that comes out of the electrical control panel. 30 amp. Basic research says this may be Normal but I am super noise sensitive....

Have you taken the front cover off the converter to see if you can pinpoint what is hissing? Given it is a 95 model it is probably full of dust around the converter components and a good blowing out with compressed air may resolve the noise.
