Electrical breaker box is buzzing-why??

No! Do not upgrade the breaker. The wire must also be upgraded if you do. Try plugging it in a different room. Is the problem still there?

Yes. For some reason this breaker box works on only one side of my house- in two of the bedrooms and the living room. The other bedroom and a side of the living room are on the outside breakers. The kitchen has had new circuits added and is also outside.
It just seems dangerous to me to have a circuit overloaded like this. This house was built in 1954, and all the wiring is original-horrors! I just had the kitchen redone, thus the reason they needed to add three new circuits, so that area is a-ok. But to simply plug in an iron and have this buzzing breaker really scares me. What do you recommend?

Is it a 15 or 20 amp breaker? What brand is the breaker and panel? How many rooms does that one breaker control?

purely an unprofessional opinion here. I’m guessing your breaker box is struggling to trip that breaker. With the iron running, if you were to plug a microwave or some other hi watt gadget, I’d bet your breaker would trip.

If you can afford it, consult with a professional electrician.

No offense intended, but this sort of question, hahahahaha… I would not rely on a bunch of net kooks like us.

household electrical issues are major.

Im a union electrician

Cool.

The breaker controls two bedrooms. It is a 15 amp, but don’t see any markings with any brand name. Appreciate your help!

The first step I would take would be to change the breaker. It sounds like its bad. You need the same size and brand. If you do not know how to change it, call a licensed electrician. Let me know what happens. Good luck
