How to Repair a Home Light That’s Not Working
A light that suddenly stops working can be caused by something simple (like a loose bulb) or something more serious (like a wiring issue). Use this guide to troubleshoot safely and know when to call a licensed electrician.
Safety first
Turn off the light switch before touching the bulb or fixture.
If you need to open a fixture or check wiring, turn off the breaker at the electrical panel.
If you smell burning, see scorch marks, or hear buzzing, stop and call a professional.
Step-by-step troubleshooting
Check the bulb: Make sure it’s screwed in tightly and try a known-working bulb.
Check the breaker: Look for a tripped breaker and reset it fully (OFF then ON).
Check the switch: If other lights on the same switch work differently, the switch may be failing.
Check the fixture: Loose connections in the fixture can stop power from reaching the bulb.
Check the GFCI: Some circuits are protected by a GFCI outlet—reset it if it’s tripped.
