Hello,
The exhaust fan blades are in contact with the ceiling cover. I attempted to move the ceiling cover around but does not seem to stop the blades touching the cover, resulting in an annoying noise.
Looking at the blades when they were running, it seems like one side of the blades are lower resulting in contacting the screen cover - is this a normal design? or has the blade settings deteriorated over time?
Fan was installed 2 years ago and recently started making noise.
