Breaker won't reset or keeps tripping: diagnosis ladder

Emergency guide

A breaker that won't stay on is doing its job — something on the circuit is drawing too much or leaking current. Unplug everything first; if it holds, you've found an appliance problem. If it still trips with nothing plugged in, it's wiring, and that's a same-week electrician call.

What to do, in order

Kill everything on that circuit: unplug devices, switch off lights, note what rooms went dead.
Push the breaker fully to OFF (it must seat) then to ON. A half-reset breaker feels mushy and does nothing.
If it holds with everything unplugged: add devices back one at a time; the one that trips it is your culprit.
Bathroom/kitchen/outdoor breaker? Press the TEST then RESET buttons on any GFCI on that circuit first — a tripped GFCI upstream mimics a dead breaker.
Still trips with nothing connected? Stop resetting it — repeated resets into a fault can damage the panel.
Note burning smell, warm breaker, or a breaker that won't physically stay OFF — those are panel-level problems: call today.

Red flags — stop and call a pro

Burning smell or warm breaker face — fire risk, main breaker off, electrician now
Buzzing or crackling inside the panel
Scorch marks around a breaker or the panel trim
Two breakers tripping together on unrelated circuits — possible utility or panel bus fault

Prevention

Don't run space heaters + hair dryers + kettles on one circuit; label the panel map now (2 a.m. is a bad time to learn it); schedule a panel inspection if breakers are 20+ years old or the brand is Federal Pacific or Zinsco.
