Breaker Won't Reset
A circuit breaker that trips and will not stay on — the circuit has a fault that must be found before you reset again.
- System
- Electrical
- Causes covered
- 7
- You can check
- 2 without a technician
Stop and read this first
- Do not reset a breaker more than twice. Repeated resetting of a faulted circuit causes fires.
- Never replace a breaker with a higher amperage rating — the wire is sized for the original breaker.
- A buzzing breaker, warm panel cover, or burning smell means shut off the main and call an electrician immediately.
- Never bypass, tape, or wedge a breaker closed.
Work through these in order
Ordered from most to least likely. Working top down means you rule out the cheap, common causes before paying anyone to look at the expensive, rare ones.
Faulty appliance on the circuit
CommonYou can check- How to check
- Breaker tripped when a specific device was running. Unplug everything on the circuit and try resetting.
- The fix
- Plug devices back one at a time to identify the culprit. Repair or replace the faulty appliance.
Short circuit in wiring
CommonNeeds a pro- How to check
- Breaker trips instantly on reset with nothing plugged in. May hear a snap or pop.
- The fix
- Leave the breaker off and call an electrician. A short in concealed wiring must be located and repaired ($200 to $800).
Ground fault on a GFCI-protected circuit
CommonYou can check- How to check
- Circuit serves kitchen, bathroom, garage, or exterior outlets. Moisture may be present.
- The fix
- Dry all outlets and reset. If the GFCI breaker or outlet will not reset, an electrician traces the ground fault.
Failed breaker
PossibleNeeds a pro- How to check
- Breaker handle is loose, wobbly, or feels different from others. Breaker trips at low load.
- The fix
- An electrician replaces the breaker ($150 to $300). Never substitute a different amperage rating.
Arc fault detected by AFCI breaker
PossibleNeeds a pro- How to check
- Bedroom or living area circuit. AFCI breaker trips with nothing obvious plugged in.
- The fix
- An electrician locates the arcing connection — usually a loose wire at a switch, outlet, or light fixture.
Damaged wire from renovation or pest
PossibleNeeds a pro- How to check
- Problem started after construction, drilling, or signs of rodent activity near wiring.
- The fix
- An electrician locates and repairs the damaged section. Rodent-damaged wiring should be inspected throughout the run.
Defective panel (Federal Pacific or Zinsco)
UncommonNeeds a pro- How to check
- Panel label reads Federal Pacific or Zinsco. Breakers fail to trip properly or will not reset reliably.
- The fix
- Replace the panel ($2,000 to $4,500). These panels have documented failure-to-trip histories.
