The only time I have had my GFI's hum is when they were being powered by a modified sine wave inverter. I have a true sine wave now and no hum

Humming does not indicate a ground fault - it would trip instantly if there was one.

If using the inverter, Luc2go is probably right.

Hi there,
As being said by other post, try to diagnose this problem by plugging -in, the MH first to the shore and then check if there is still a hummmm. If it's gone, it means your modified inverter is causing the humm co'z using modified inverter, you are not getting the true sine ac voltage which is the same as our household current. But if you are not using this GFI outlet for sensitive elecronic device, a modified inverter and that humm are OK.
