OT electricians, why does a 15A breaker keep tripping?

Noticed it was tripped the other day. Flipped it back, no problem. Yesterday I plugged in my electric smoker and it immediately tripped. This breaker is for the master bedroom lights and some outdoor outlets. The smoker worked fine in another outlet on a different breaker. So, I figured it was the smoker, but, overnight while the line was seemingly not in use, the breaker tripped again. Is the breaker bad or something else? It's a 14 year old home.

Breakers do wear out eventually. Either that or two much on the circuit.

Check your flux capacitor.

Bad splice somewhere probably.

Get another breaker and swap it out to see if it's the breaker or the line.

How old is the home? Is there is GFI outlet or breaker on this leg with there being outside outlets?

With nothing seemingly on the circuit? When the smoker worked fine on another 15a breaker? I'm to ignorant about this to be joked with, it's not sporting.

Test it by removing it and using one of the other 15A from the panel. See what happens.

Yes, breakers do get weak or go bad over time

Could be a broken widget in the micro capacitor of the plarnax

Sorry baw. Best bet if you don't know much about it, get a professional to come check it out.

I would put a clamp meter around the wire coming from that circuit and measure the amperage. If it's close to 15 then you need to see what's making the draw.

If it's not close to 15 or it's low, (with just lights and fans you may be drawing 5 amps tops)
I would then replace breaker as that's the cheapest fix.
If your amperage is low and breaker good, then you have a short or a grounding somewhere. A loose outlet can cause this. So can rodents chewing wire.

If the circuit is common to a bedroom, the breaker SHOULD be an arc fault breaker, not simply a GFCI circuit.

It may have gone bad and need replacement, although usually when they have gone bad, they trip with normal everyday loads.

Your smoker may have a small short in it, or maybe just the way it works is fooling the breaker into thinking it has a fault.

I appreciate the jokes, so long as I recognize them as such and don't go looking an hour for a kerfoddlin rod in my flux capacitor.
