Arc Fault breaker tripping

My arc fault breaker for master bed room is tripping. When I tried to switch it back to on position it is tripping again.

My house is 2 years old and last month my builder's warranty just got expired.

I have had this same tripping problem about 6 months ago and the builder fixed it. The explanation from electrician was that two wires were very close in one of the sockets.

I have two Arc fault breakers, one for master bedroom and another one for two other bed rooms. Master bed room breaker is the one that I am not able turn on, but when it trips, it trip the other arc fault breaker too.
One interesting thing I have noticed is, it doesn't trip if I tried to turn it on during night time (around 9 PM), but it trips during the day time.

Now, the only thing I could think of the reason for the reemergence of this issue is, pest control. He has gone to the attic and spread some powders, and also removed sockets cover and checked for insects.

Any ideas ?

Thanks.

Lots of things can potentially cause this. Moisture comes to mind first.

The solution is to divide and conquer. You just keep disconnecting things from the circuit until you can reset the breaker.

We have the same setup in our house, where the master is on one and the other 2 bedrooms is on the other. The electrician came out and it tripped when he was here too. He replaced all of the receptacles in both bedrooms. The problem will come back about every 6mos. or so. I just go out to the garage and reset the breaker. I have also heard that once you reset the breaker and it immediately trips again, it could be a bad breaker. The way that I know of to test it is to flip it to "off" then back to "on" about 3 times. If it keeps tripping after that, it's possible that you have a bad breaker.

Not a good test. The same thing will happen if you actually have a fault. And resetting a tripping breaker over and over again may cause damage in the circuit.

Breakers do fail, but not very often.
