Sometimes power may be lost to a light fixture, receptacle, appliance, or electronics. Other times a circuit breaker or GFCI will trip for some unknown reason. In this section we will try to help you understand and fix the problem before calling an electrician.

Flickering Lights and Intermittent Loss of Power

Flickering lights and an intermittent loss of power are usually attributed to a loose wire connection. A loose wire connection can cause the wire to overheat, eventually causing the connection to fail. Sometimes a loose connection will make a crackling noise. A loose wire connection could happen in any of these places:

Tripped Circuit Breaker

Trips right away (within a few seconds)

Trips occasionally

Electrical Troubleshooting
