Blue Fan Canopy + Blue switch creating fan motor hum sound

Hello team,

I have a basic Hunter fan - AC with not smart features (pull strings for light and fan speeds).

The fan motor is making a hum sound. To eliminate variables, I replaced the Blue switch with a basic toggle on/off and removed the Blue Fan Canopy which resulted in a 70% reduction in fan motor hum. Hunter are going to send me replacements as a hum can be heard if paying attention to sound. But, I am concerned about the BLUE hardware causing more noise?

Double checked the wiring. I am using Z2MQTT

Any thoughts or recommendations are welcome.

Which switch, exactly?

I wired my canopy module via the load terminal of my 2-1 switch the other day, and people here pointed out that it was not correct. So I re-read the wiring diagram, and of course I was wrong - both the black line (from panel) and black load (to canopy module) should go to the same line terminal of the 2-1 switch… to illustrate:


And that addressed the humming/buzzing motor issue, at least for me.

Don’t know whether my experience would help, but I figured I should share anyways.
