    And reported that this hum from the fan controller was normal.?

    Some times a transformer will make a humming noise but that can be solved by tightening the screws attaching it or by replacing it. A relay will not normally hum if it is not energised (no power to it) whereas a transformer has power all the time. Good luck. Mike
