Humming sound
 
Rear bedroom humming sound 35k bounder; any thoughts what it's from?

Transfer relay switches are known to hum . . . .

Ditto for converters.

I recently discovered the transfer relay behind what looked like a heat vent in the bedroom of my '05 32w Bounder. Mine doesn't hum, but if it did it would be well positioned to be heard. Take a flashlight and see if your heat vent is really just a cover over the hole leading to your transfer relay.

You may want to tell everyone if you hear this humming all the time or just when you are plugged in. If only when plugged in then your mystery is most likely solved above.

Water pump?
