Thankfully it's one I don't use that often, but I don't do anything to trip it and it randomly trips a few hours after I reset it. It's the breaker that controls a few outlets along my kitchen wall. I noticed one time that nothing plugged in was working, so I went to the garage and turned the switch off and on again. The little "reset" red light blinks and then I press that and it trips it again and then I switch it off and then on and then it seems to be normal. Then, [b]I don't do anything[/b], and in few hours, lo and behold, it will trip again. I don't plug anything in that overloads the currents, so I'm confused on why this happens. Also, how would an electrician even begin to figure out how to fix this? Do electricians know what goes on behind the walls of my house? I hesitate to call an electrician because 1) it's a sporadic problem and I might not be able to replicate it if he/she comes over and 2) I don't want the electrician to be cutting up the walls of my house to inspect the wires (expensive) if there's an easier fix. Thanks, guys. PS: This is a new home. Brand new for us (nobody lived here before), and we've only been here for 2.5 years.

Last week a church across the street from us burned down and damaged some electrical and Spectrum stuff at the pole. They fixed it pretty quickly but all of our AFCI breakers (with outlets, we have some lights only circuits with AFCI breakers that have had no issues) have been tripping lately. The first thing I noticed was the projector in the living room, upon turning it on the breaker would trip right away. I hooked up an extension cord and ran it to a different circuit (not AFCI) and had no issues. Then I plugged it back in at the ceiling outlet where it was and it works sort of now...it still trips the breaker eventually but lasts anywhere from 5 minutes to a couple of hours before it trips the breaker. I called an electrician and he said that it could be the bulb in the projector and to try that before doing anything else more costly if I had a spare bulb (and I did).. That circuit went 48 hours without tripping with everything plugged in but just didn't use the projector. Tripped within 10 minutes of turning it on. Replaced the bulb and tried again but it still tripped within 10 minutes. The bedroom circuit occasionally tripped the first couple of days after turning on the bedroom TV but we have used it for days now normally without issue. We have a dehumidifier and a fish tank on the hallway circuit that was also tripping within minutes of turning on the dehumidifier. We unplugged the dehumidifier and now it is tripping about once a day. Thew past couple days it is fine when we leave in the morning but has tripped by the time we get home from work. Then we reset it and it is still going when we leave for work the next morning but it is tripped again when we get home. So today we unplugged the fish tank and will see if it still trips. My understanding is that if it trips with nothing plugged in then it is a wiring problem in the wall or the breaker itself. So total, 3 breakers tripping (master bedroom, living room, and hallway). This past weekend my father in law (who is an electrician, though he mostly does industrial work these days) came over and replaced the AFCI breakers for us (which cost a pretty penny I might add, lol) but still having the tripping issues as described above. He then checked the outlets used by all these appliances and didn't see any issues. He did lots of multimeter stuff that I know nothing about but ended up saying that the only thing he can think of is that the fire caused a surge and damaged several of our appliances causing the breakers to detect an arc fault. He spent a total of like 8 hours at our house and basically he said he had no idea why everything in the house works fine except for a handful of appliances that we have never had issues with (including one not plugged in recently) unless they were somehow damaged in a surge event and said maybe try to find an AFCI specialist. This house is less than 5 years old (we moved into it soon after it finished construction, around November 2014). I am just really frustrated with this whole situation and financially speaking, right before Christmas is really a bad time for this to happen. Projectors aren't cheap and I can't really afford to replace it if there is nothing really wrong with it, but as I said it works flawlessly on the kitchen (GFCI) circuit. I am on the verge of just trying to talk my father in law into replacing them with standard breakers. Any suggestions of things to try?
