Reset (or Replace) a Tripped GFCI Outlet

A GFCI outlet (the one with TEST and RESET buttons) trips when it detects a tiny electrical leak — often saving you from a shock. Most trips are nuisance trips after a storm or a damp tool, but a GFCI that won't reset (or trips repeatedly) is telling you about a real problem.

If it won't reset, don't just keep pressing itA GFCI that trips immediately on reset is detecting a real fault — usually moisture, a damaged appliance, or wiring damage. Find and fix the cause before bypassing.

Steps

  1. 1

    Try the reset first

    Press the RESET button firmly. If it clicks in and stays, you're done — the outlet may have tripped from a storm, brief power surge, or moisture that's now dry.

  2. 2

    Find the upstream GFCI if your outlet has no buttons

    In bathrooms, kitchens, garages, and outdoors, multiple regular outlets are often protected by one upstream GFCI. If your bathroom outlet is dead but isn't a GFCI, find the GFCI in another bathroom, garage, or basement and reset it.

  3. 3

    Unplug everything and try again

    If reset trips immediately, unplug every device on that circuit. Try reset again. If it now holds, plug devices in one at a time — the appliance that retrips it is the culprit.

  4. 4

    Check the breaker

    GFCIs and standard breakers can both trip together. Walk to the panel, find the breaker for that circuit — fully off, fully back on.

  5. 5

    If still tripping after unplugging everything — replace the GFCI

    GFCI sensors can wear out and trip falsely. Shut off the breaker. Use a non-contact voltage tester to confirm the wires are dead. Unscrew and pull out the outlet. Note: GFCIs have LINE (power coming in) and LOAD (power going to downstream outlets) terminals — wires must go on the same labeled terminals on the new outlet or downstream outlets lose power.

    Tip: Take a photo before disconnecting wires. The colors and positions matter.
  6. 6

    Wire the new GFCI

    LINE terminals get the wires that have power when the breaker is on (test with the breaker briefly back on, then off again). LOAD terminals get the wires going to other outlets downstream. Hot (black) to brass, neutral (white) to silver, ground (green/bare) to green.

  7. 7

    Test the new GFCI

    Restore the breaker. Press TEST — the RESET button should pop out and the outlet should go dead. Press RESET — power restored. If TEST doesn't pop RESET, wiring is wrong. Recheck.

  8. 8

    When to call an electrician

    GFCI keeps tripping with everything unplugged AND it's a brand-new outlet. That points to a wiring fault inside the wall — moisture in a junction box, a damaged cable, or a backstabbed connection failing. Worth a professional diagnosis.
