rpbuttery Report post Posted March 15, 2016 The GFCI outlet in my bathroom (2011 Tiffin Allegro Open Road RED)--the only GFCI outlet in the coach--has developed a buzzing noise, but only when on the coach batteries. That is, when on shoreline power, there is no buzzing. It hasn't tripped, and resetting it has not stopped the buzz. Any thoughts? Share this post Link to post Share on other sites
desertdeals69 Report post Posted March 15, 2016 Is it when on the inverter? Its possible there is something wrong with the inverter. Share this post Link to post Share on other sites
casuall454 Report post Posted March 15, 2016 Is it when on the inverter? Its possible there is something wrong with the inverter. Test voltage of outlet on inverter power and then on shoreline lower. GFIC - Outlets can fail over time, you could have a "bad" unit although purchasing a new outlet to test that theory can get very expensive. Last thought; obtain make and model of outlet and preform internet search for documented recall from UL, FTC, NFPA-70 or the manufacturer. Best of luck on this, I rather have a failed part then trouble shooting 25 possible causes. Share this post Link to post Share on other sites

hermanmullins Report post Posted March 15, 2016 Have you pushed the Test Button on the buzzing GFI?. If the Buzzing stops replace it. Herman Share this post Link to post Share on other sites
rpbuttery Report post Posted March 15, 2016 Also, yes, when the inverter is on. Test and reset has worked fine several times, but doesn't stop buzzing. Buzzes only on inverter/coach batteries, not shore power.Thanks. Share this post Link to post Share on other sites
kaypsmith Report post Posted March 15, 2016 $7.00 to $14.00 for a new outlet, if you can't afford one, pm me your shipping info and I will send you a new one. But as DD said, could be inverter issues. Good luck. Share this post Link to post Share on other sites

kaypsmith Report post Posted March 15, 2016 Carl, last time I tried to ship you something, came back to "RETURN TO SENDER, ADDRESS UNKNOWN", LOL. Also, don't why the emotions are grayed out on my posts, guess I need to PM Todd. Share this post Link to post Share on other sites

rpbuttery Report post Posted April 16, 2016 And the beat goes on... Related to my original March 14 posting above regarding the buzzing GFCI outlet--but buzzing only on inverter: RV repair techs swapped out the GFCI. Still buzzed. They then replaced the modified sine wave Xantrex Freedom 458 inverter, which did test as marginal. Still buzzed. After consulting with Xantrex, the techs swapped the GFCI outlet for a different brand GFCI suggested by Xantrex. Still buzzes. Supposedly, the new inverter and new GFCI tests as ok. Any further thoughts? Share this post Link to post Share on other sites
hermanmullins Report post Posted April 16, 2016 Replace the GFCI with a Standard plug.:-) Might not help but it can't hurt. Herman Share this post Link to post Share on other sites

Any further thoughts? rpbuttery, Have the techs checked the wiring of the inverter input power and the inverter power output Ground circuits and the Neutral Circuits have a good connection and and wired to the proper terminals. The 458 unit did test marginal and xantrex sine wave inverters need to be wired correctly. Thinking a slight potential difference between the 2 points or wiring issue could be the culprit. ! Rich. GFI units sense the slightest difference ! and you have already installed different units. Share this post Link to post Share on other sites
rpbuttery Report post Posted April 26, 2016 And on, and on, and .... No solution yet. All diagnostics and test results are negative. Last straw being clutched--changing inverter to a pure sine inverter from modified sine, and Magnum from Xantrex. Hope! Share this post Link to post Share on other sites

manholt Report post Posted October 31, 2017 NK. Welcome to the Forum! Have you checked wiring to CB? If any are touching each other when pushed into wall...you get bleed over. Have you pushed the re set button? Make sure each wire is in the correct hole and the bare wire(ground) is good and tight. Share this post Link to post Share on other sites
