A family member's house was completely rewired in 2011 and has arc-fault
breakers for the bedrooms. One of those breakers will not hold in at all, even

Is substituting a replacement breaker the most appropriate first step, or is
there something else to try first?

Are you sure there's nothing *else* on the outlet circuit?
E.g., light in closet, etc.?

And, does the breaker feel "limp" as you try to set it? Or,
does it feel right (stiff) but trip just as it "sets"?
