Tripping AFCI and Open Hot


I purchased a freshly renovated house 6 months ago and a AFCI breaker started tripping randomly 2 months ago without anything being plugged or unplugged (weeks or more between trips with no correlation). I got a three-prong receptacle tester and found that one outlet is showing an open hot, but it does have power to it.

Are the two likely related? I replaced the one outlet in the circuit that was showing this, but that didn't help. I checked the previous outlet in the chain, but no connections were loose and were not done with pig tails. Is it worth replacing this next outlet or is this one a time to call in a pro?

(FYI, after discovering the open hot the breaker is just left off)

Thanks in advance!

Welcome to the forums.

The circuit is off so you know which receptacles are affected. You may have to check them all for the problem. While you're checking.... make sure the backstab (push in the back of the rec.) connections aren't used. The use of them is a common problem area.
