    Hi Bill,
    The hum may be coming from something that is plugged into or connected to the Load side of the GFI circuit. If this is a stand alone GFI then the GFI may be older or need replacing.
    I hope this helps,
    Dave

    My GFI works fine except my intercom radio hums when on, but does not hum when I trip the GFI, the radio is on it’s own separate circuit, what is the problem?
