Arc-Fault Circuit Interrupter Breakers (AFCI) have integrated computer chips that identify a disturbance to the standard electrical current of the circuit it protects. AFCI breakers are different from standard breakers which only protect for over-current issues. If an arc-fault circuit is not working, turn off all devices and turn off all switches before testing the breaker. At the main panel, press the yellow “TEST” button on the AFCI breaker for the affected circuit. It should NOT click indicating it has already tripped. If the breaker clicks, try the next AFCI breaker until you find the breaker that does NOT click. For each breaker that you have tested, you must reset the breaker by following the same steps for a standard breaker.
Once the correct breaker is reset, plug in each device and turn on each switch independently to determine if any of the connected loads are causing the breaker to trip. In many cases, an old or failing product may cause the AFCI breaker to trip indicating a safety issue. Please repair or replace the device accordingly. If the breaker fails to reset and trips after several attempts, there may be a more serious problem. Please contact us to discuss the issue in more detail
