How do I troubleshoot a dead GFCI receptacle?
To troubleshoot a dead GFCI receptacle in a residential system: 1. **Verify Power Supply** - Check the circuit breaker/fuse for the GFCI's circuit. Reset the breaker or replace the fuse if tripped/blown. 2. **Test Other Outlets on the Circuit** - Determine if other outlets on the same line have power. This helps isolate whether the issue is upstream. 3. **Reset the GFCI** - Press the "Reset" button firmly. If it doesn't stay reset, there may be a ground fault or wiring issue. 4. **Check for Tripped GFCI Downstream or Upstream** - Some GFCIs protect other outlets. Locate and reset any other GFCIs in the circuit. 5. **Test for Voltage at the Receptacle** - Use a multimeter or voltage tester to check for ~120V between Line Hot and Neutral terminals. - No voltage indicates a wiring or upstream power problem. 6. **Inspect Wiring in the Box** - Turn off power at the breaker first. - Remove the receptacle and check for loose, corroded, or reversed line/load wires. - Confirm Line (power in) is connected to the GFCI Line terminals, not Load terminals. 7. **Replace the GFCI if Necessary** - If wiring is correct and power is present but the GFCI won't reset or provide power, replace the device. **Assumptions:** - Power is coming from a standard residential 120V source. - No unusual load conditions or outdoor/weather exposure issues. Following these steps should identify the cause of a dead GFCI and guide you to a fix.
