Coach light whine noise October 22, 2020, 03:15:57 pm So the coach light in my 2005 30' TB in the kitchen/entry area and is connected to the light switch by the door makes an obnoxious noise when turned on. But none of the other lights do it when on. Has anyone else experienced this and if so how do I fix it? Juanita
Re: Coach light whine noise Reply #1 – October 22, 2020, 03:30:33 pm "...makes an obnoxious noise when turned on."As an owner of a '04 30'IB I know the switch of which you speak! If I remember it's the 3rd of four switches just inside the entry door, located there, I suppose, so that you can have an overhead light prior to making an entry.Are you certain that the obnoxious sound is emanating from that overhead fixture?While I have never experienced a sound of any sort from my light that does not help with your problem! I suggest that you pop off the cover and rotate the tubes back and forth a few times to see if that would help. Another source for a irritating sound may be the ballast that drives the light. If that were the case it would be necessary to replace the fixture. But again, there are options... you could convert the fluorescent to LED and in the doing bypass the ballast. 1 Likes

The fluorescent lamp's ballast may be going bad, if so, it's time to convert it to LED tubes.led replacement tube lights for 12v RVs and TrailersIt's a relatively simple conversion. LEDs use a fraction of what the fluorescents use.Larry 1 Likes

Re: Coach light whine noise Reply #5 – October 22, 2020, 05:00:18 pm Juanita; I use this link directly to the natural white 4500K bulbs. Two required. I find these so close to the original look that you can't tell them from the 'cool white' flourescents that were original equipment. : LED Replacement for 18" T8 Tube LightsThese are 18" T8 tubes.

Re: Coach light whine noise Reply #6 – October 22, 2020, 06:22:12 pm I did a couple fixtures and went ahead and ordered enough to finish out the coach. They are an easy install just have a small hand full of small blue wire nuts and a decent wire stripper. The bulb covers can be a little tricky to get off on the first one.Jon
Re: Coach light whine noise Reply #7 – October 22, 2020, 09:06:55 pm Juanita,The advice you’re getting to replace the fluorescent light with an led light will most likely solve your problem. However, troubleshooting and locating strange sounds made me think of something my father taught me while working on my first car. Take a short length of hose, like clear vinyl that can be found at any big box store. Hold one end up to your ear and probe the other end around where you think the sound is coming from. Be sure to make contact with what you think is the sound source. This actually works quite well. Other things such as a length of broomstick will work too but I’ve found vinyl hose works for me. FYI, my first car was a 59’ mga and my sound finder was a length of garden hose. Good luck in troubleshooting your mystery sound.- John 2 Likes

In other words, a poor man's stethoscope. 2 Likes
Re: Coach light whine noise Reply #10 – October 23, 2020, 11:32:58 am Hi Joan,Sound will travel along any solid mass. The more dense the mass, the better the sound will travel. A hardwood broomstick works in a pinch but you must make contact with the sound source for it to work. I’ve used this method to isolate which cylinder had a ticking rocker valve. The hose method is somewhat different because the sound is traveling through the air in the center of the hose and not necessarily the hose itself. In Juanita’s case, I think a hose would work best. 😃- John
Re: Coach light whine noise Reply #11 – October 23, 2020, 12:24:24 pm Thank you, John. The issue I might have is when the located noise reaches back to the "solid mass" which is my head! 1 Likes
