High Pitch Sound High Pitch Sound by Jo (Washington) Question: I have a small Quicksilver, new. When plugging in, a high pitch noise occurs at fuse box. Help…what is wrong? I have camped all week 4 different spots without a problem or the noise. Answer: Sounds unusual to us. We are not clear if the sound is at the pedestal or your RV’s fuse box itself. You could talk to the campground staff where you are camped. Another idea is to go back to one of the camping spots where you previously did not have a problem and see if you have the problem now. That would tell you if something has just recently gone wrong. Unless it is an issue with a specific campground site, we suggest you get it checked out by a qualified RV facility. Better safe than sorry. Other comments? Click here to post comments Return to RV FAQ.
