    I told him to contact the appliance guy. Now go figure

    I will check into the where the other AFCI's are located in the panel when I go back there.

    I explain what trips a device, that either it's tripping because it should and the problem is either the load or something is fooling it, or it's tripping because it's bad, and we try substitution.

    Modern gas stoves/ovens often use a spark generator to light the pilot. (The other method for lighting the pilot is a glow plug. Modern appliances do not keep a pilot lit 24/7.) I suspect that a spark generator produces noise on the supply line that "looks" like an arc.

    EXCELLENT!!

    "Looks" like an arc? Maybe because it is an arc? This is a great observation Jon that everyone doing residential work should keep in the back of their mind.

    Yes it is!
    I had read about that in an earlier post.
    That was where I was leaning towards on my point #5.
    I wrote it hoping it would be helpful to Charlie or anyone else.
    Now the challenge is to find out if it truly is an appliance issue.

    It is an arc, but it is typically on secondary side of a transformer and not an arc occurring in the actual supply circuit to the appliance.

    Inductive kickback, even from something on the supply side of the AFCI or even a GFCI sometimes causes troubles also. In those cases nothing is wrong with the protected circuit yet it still trips and us installers are the ones getting a bad name and eating costs trying to make clients happy.
