I have a GFCI in my kitchen that seems to keep making a clicking
noise. The GFCI is connected to one other outlet along the
countertop. The funny thing is that it keeps doing this every 15
minutes or so even after it has tripped off (without me reseting it).
This is the same noise as if it is tripping from the on to the off
state. This is all happening while nothing is plugged into the
outlets.
I have tested that the GFCI is working by plugging a light in and the
light works when the GFCI is set, but turns off when I press the test
button.
Is it a bad GFCI outlet?
Is this some way of indicating to a person that it has tripped by
making the noise?
Is there somethign wrong with the wiring that I need to take a look
at?
Any advice or other thoughts are appreciated.

This has happened to me, but more than just a little clicking, more
like a continuous buzz. What caused it for me is the use of my 2 meter
ham radio transmitter. I suspect the RF went down the line in common
mode and triggered the detector that was sensing a current sum in the
conductors (and indication that an appliance was leaking current to
ground somewhere). Normally the current summed in the hot and neutral
wires should be zero at all times.

Maybe a bad unit, or maybe a bad design being triggered by something
else. Or maybe something in the wiring cascaded downstream from it,
if you have any like that.

Does it only do it if tripped off? I've never heard of such a thing but
I would not rule it out.

That's one possibility. You need to find out what all is on that circuit
cascaded through that GFCI.
