Hello. I have a 2019 RW 3901 wb. When the A/C is on, there is a loud vibrating noise in 1 of the bedroom A/C ducts. When I put my hand up into the duct (which is not very far) I can feel the "floor" of the duct vibrating.
Has anyone else experienced this and does anyone have a solution?
Have a Blessed day and be safe!
They may have left a piece of duct loose or a scrape of duct or tape in there. I found a large round piece blocking one of my vents. When I pulled the vent it was the piece of duct from when the drilled the hole for the vent.
