What causes a light switch to stop working but light stays on?

When a switch no longer controls a light that stays on, it indicates a fault in the switching circuit that needs professional diagnosis and repair. Our electricians perform on‑site inspections, testing, and corrective repairs to restore safe operation. If you notice burning odors, buzzing, or sparking, turn the breaker off and call us right away. We handle general electrical repairs, switch and wiring issues, and panel-related causes. We serve homes across Ashburn, Alexandria, and nearby areas.

• Note any burning odor, buzzing, or sparking
• Avoid repeated toggling; turn the breaker off if concerned
• Schedule diagnostic service
