A faint hum is the transformer-like sound of current. A loud buzz or crackle is a loose connection — call today.
Three causes cover almost every call we get for this.
A terminal screw that backed off, or a breaker not seated on the bus bar. Current arcs across the gap.
An overloaded breaker that buzzes instead of tripping. Common on Federal Pacific and Zinsco panels.
A dryer or heat pump on a worn breaker. Hums under load, warms, eventually fails.

Traced to the box or device it lives in. Exact price before any work, you approve it first.
Right parts, tested under load, next connection checked so it does not come back.
A faint, steady hum from a panel under heavy load can be normal. A breaker that buzzes loudly, crackles, sizzles, or buzzes and feels warm is not: it has a loose connection at its terminal or on the bus bar, or it is carrying a fault current it should have tripped on and cannot. Turn that breaker off if you can do so safely, and call today — buzzing breakers are how panels burn.
Loud buzzing, crackling, heat or a smell: yes. Turn the breaker off if you can and call (206) 486-6373.
Same-day priority for a buzzing or warm breaker.
Exact price after we see the panel, before any work starts.
Not usually — a connection or a single breaker is the common fix. If the panel is a Federal Pacific or Zinsco, replacing it is the honest answer.
