Buzzing Light Switch in Leesburg, VA

A buzzing light switch is telling you something is wrong inside the box — usually arcing from worn contacts or a loose wire connection.

We diagnose the cause and repair or replace what's needed before the problem gets worse.

Symptoms

• Buzzing sound when switch is on
• Crackling noise from the switch
• Buzzing gets louder over time
• Switch buzzes with specific lights or fixtures
• Buzzing with warmth at the switch plate

Common causes

Several different issues can create similar symptoms. These are the most common causes we see in Leesburg homes:

• Worn switch contacts arcing when closed
• Loose wire connection at the switch
• Switch not rated for the load (common with some dimmers or fans)
• Failing switch mechanism
• Loose connection at the light fixture

What you can safely check

These simple checks may help, but do not open panels, remove devices, or touch wiring. If you notice heat, sparking, or a burning smell, stop and call us.

• Stop using a buzzing switch until diagnosed
