The answer to 'why is my junction box not working' is that there could be several common causes, such as loose connections, damaged wiring, or a tripped circuit breaker. Junction boxes are used to connect and distribute electrical wires, and if any of these components are not functioning properly, it can result in the junction box not working.
Some common symptoms of a malfunctioning junction box include flickering lights, outlets that don't work, or breakers that keep tripping. To troubleshoot, you'll want to first check the circuit breaker and make sure power is getting to the junction box. Then, you can inspect the connections inside the box to ensure they are tight and the wiring is in good condition. If you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and repair the issue.
