The answer to 'junction box not working' is that there are several common causes, including loose connections, damaged wiring, or a faulty circuit breaker. Symptoms may include flickering lights, outlets not working, or the box feeling hot to the touch. Solutions can range from tightening connections to replacing the entire junction box, depending on the issue.
In many cases, homeowners can troubleshoot and fix minor junction box problems themselves. However, for more serious issues or if you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and repair the problem safely.
