What causes a light switch to stop working but light stays on?
A light that stays on when you flip the switch usually means the switch failed or the wiring was altered or loose so the light is no longer being interrupted. Our licensed electricians diagnose the root cause, test the circuit, and repair or replace the switch or wiring. If you smell burning or hear buzzing, treat it as urgent. Same-day service is available in Colorado Springs and nearby when booked before 2 pm.
Quick steps:
- Turn off the circuit breaker to that light.
- Do not attempt DIY if there are odor, heat, or sparks.
