In this video I demonstrate how to fix an faulty outdoor outlet. There are several steps to troubleshooting. You will see that I took the long approach and went down a rabbit hole at another point. We got it working in the end.

In the first step you need to identify the outdoor outlet that is not working. Hopefully, it is connected to a GFI circuit breaker or to a GFI protected outlet. Remember, there is no guarantee that it is. Do not assume and make sure you turn the breaker off when you work on electric. Not only should you use a plug in tester (that also tests GFI circuit testing) but you should also use a DMM or voltage tester to verify that voltage doesn’t exist at the hot wire where you are working, i.e. the breaker is off. Do not assume that because there is no voltage at the wire that it cannot suddenly become live. If someone flips a switch or a loose wire in another part of the house suddenly makes contact you may be in a world of hurt if you are on the receiving end of this.

Once you identify the outdoor outlet that is faulty you will need to check to see if there is a breaker labeled for this outdoor outlet. It could be that there is a breaker that has GFI capability built into it, which means that you may or may not also have a GFI outlet. GFI breakers and GFI outlets do go bad. Connections to the outlets do go bad, especially those outdoors because they are exposed to moisture which can speed up corrosion. Temperature fluctuations on outdoor outlets are more prevalent and can lead to loose connections over time.

You diagnose the problems by starting at the faulty outlet and tracing your way back through the circuit all the way to the circuit breaker. The may be an inline GFI that could be a problem. Chances are you do not have a broken wire but more likely a loose or bad connection. But that doesn’t mean that you DO NOT have a broken wire, i.e. broken by new construction or a nail through a wall, etc.
