What causes a light switch to stop working but light stays on?
Common causes are a failed light switch or a wiring fault that’s effectively bypassing the switch, so the light stays energized. A technician can troubleshoot the switch, connections, and the circuit back to the panel, then repair or replace parts as needed.
- If you notice warmth, sparks, buzzing, or a loose fixture, turn power off at the panel and call a pro.
