Breakers are designed to last a very long time, but like switches and outlets, they can weaken over time. If a breaker stops working properly, it does not automatically mean that a full panel replacement or rewire is required.
In many cases, a simple breaker replacement is all that is necessary. If you are told that extensive electrical work is required after a breaker issue, it may be wise to seek a second opinion to ensure that the recommended solution truly matches the problem.
