The answer to 'rewiring making buzzing noise' is that a buzzing sound during electrical rewiring is often caused by loose connections or improper wiring. This can be a sign of a serious issue that requires professional attention to ensure safety and prevent further damage.
Common causes include loose wire nuts, improperly terminated connections, or incorrect wiring. Symptoms may include flickering lights, intermittent power, or a persistent buzzing or humming noise. While some basic troubleshooting may be possible, it's generally best to call a licensed electrician to diagnose and resolve the problem, as rewiring work can be hazardous for untrained homeowners.
