Generator outlets aren't working / GFCI keeps tripping

Built-in GFCI protection on generator outlets is a safety feature required on newer models, and a tripping or dead outlet is usually a moisture issue, an overload, or the reset button not being fully pressed.

Symptoms

  • No power at one or more specific outlets
  • GFCI reset button pops back out immediately
  • Some outlets work but not others
  • Outlets worked before but stopped after use in wet conditions

Likely causes

  • CommonGFCI outlet tripped and needs resettingThis is a normal protective response and just needs the reset button pressed firmly.
  • CommonMoisture in the outlet or connected cordRunning a generator in rain or high humidity without cover is a common cause of nuisance trips.
  • PossibleOverloaded circuit on that specific outletSome generators split outlets across separate internal circuits, and one can be overloaded while others aren't.
  • PossibleDamaged extension cord or connected device causing a real ground faultA genuine fault in a cord or appliance will trip the GFCI repeatedly and correctly.
  • PossibleFailed GFCI outlet itselfThese outlets can wear out and need replacement after repeated trips or age.

What to do

  1. Press the GFCI reset button firmly and listen/feel for a click, since it can be easy to press only partially.
  2. Make sure the generator and all connections are dry; let everything dry out fully if it's been exposed to rain or heavy dew.
  3. Try a different extension cord and appliance at that outlet to rule out a real fault in what's connected.
  4. Check whether other outlets on the generator work fine, which helps isolate the problem to one specific outlet/circuit.
  5. Reduce the load on that specific outlet if it may be overloaded relative to its rated circuit.
  6. Use a generator-rated weatherproof cover or tent designed for running in wet conditions if this happens often outdoors.
  7. If the GFCI outlet trips immediately with nothing connected and everything is dry, the outlet itself has likely failed and needs replacement by a small appliance repair technician.

When to call a pro

A GFCI outlet that trips immediately with nothing connected and everything dry needs professional replacement rather than repeated resetting.
