I have a 3 speed fan that was controlled by a manual skylark fan control without any issues. Last week I replaced skylark with a 4 speed RRD‑2ANF control and when I switch to the 3rd speed, the RRD‑2ANF starts buzzing.
Is there a way to disable the speed on the fan control that my fan does not like?
I guess what I am looking for is a customizable speed on a fan control. It would be great if that was an option
