When a Ground Fault Circuit Interrupter (GFCI) safety outlet fails to trip when you press the test button on a plug-in circuit tester or the physical button on the receptacle face, it indicates that the internal sensing circuitry or mechanical trip mechanism has failed completely. While the outlet may still deliver 120 volts of electricity to plugged-in devices, its vital shock-protection capability is entirely broken, leaving users vulnerable to electrical hazards. You can troubleshoot GFCI safety easily through monthly button tests. You can verify that your corrective action is successful when replacing the compromised, non-responsive GFCI receptacle with a new self-testing unit ensures that pressing the test button immediately cuts power and restores shock protection.
