eric@babin.com Report post Posted March 13, 2022 2014 Itasca Ellipse 42QD. I have a saying "Easy Day" which means this.... when something bad happens / something breaks, and you start to think.... oh crap, this will cost a couple hundred bucks to fix (or in some cases thousands) but after a few minutes you've got it fixed for nothing, or almost nothing. Today's example: Exhaust fan's cover opens but fan doesn't come on. Check fuse: It's good. Check switch: It's good (continuity check) Check for voltage at switch: None. Go up on the roof to look for a part number on the other side of the fan and just for giggles I jiggle the ground wire..... fan comes on.... and there you have it.... Just a loose ground wire Sharing this experience to if anyone else has an inop exhaust fan after checking fuse and switch... check ground. Here's the pics: Red arrow pointing at ground wire. This is the top of the fan. Share this post Link to post Share on other sites
wildebill308 Report post Posted March 14, 2022 So did you take the connection apart and clean it and treat it with corrosion preventative so you don't need to go back up on the roof next week? Bill Share this post Link to post Share on other sites
rayin Report post Posted March 16, 2022 FWIW over 80% of all 12V issues are the result of a poor/missing ground. Share this post Link to post Share on other sites
