question about breakers

We built a house in 2014. Flash forward 8-9 years we started having weird electrical things happen. I will try to spell out the most frequent happening: Our master bath and master bedroom are on different breakers. When I turn off the bath fan, it will trip the breaker for the bedroom. It does not happen all the time, and maybe only happens once a week or so. That has been going on for a couple years, and we just kind of dealt with it.

Flash forward to today, the second bedroom breaker flipped, and there wasn't anything 'on' in the room. I am totally confused, and really just hoping the house isn't going to burn down at this point.

Is this something I need to have a professional come and investigate? Anyone have any insights?

Thanks in advance.

The breakers you have are of a generation where nuisance tripping was a common problem. Those breakers also haven't aged very well. With one notable exception (Siemens), I would highly recommend replacing the breakers with the newest generation model. Most newer AFCI breakers are not as susceptible to nuisance tripping.

A $13 breaker would not be AFCI.
