My Swimming Pool Lights Don’t Work: A Troubleshooting Guide

Swimming pool lights look great at night, and they make it safer to swim. If your light suddenly switches off there are several reasons for this problem. In this article we will review step by step what you should do to find the root cause.

Preventive measures

First of all, know that when handling water and electricity you need to take prevention measures. Make sure every switch related to the pool lights is turned off. Start with the pool light switch itself, move on to the circuit breaker and switch it off. Next, tape all switches to prevent someone from coming in and turning it on while you work. Put up a sign as well, you can’t be too careful with this.

Check the circuit breaker

To find out what the problem is, your first stop should be at the circuit breaker. Is it tripped? by now you should have the pool light switch off, so turn on the circuit breaker, and if it immediately trips, it means you have a short circuit. You will need an electrician to help you further with the problem.

Check the Ground Fault Circuit Interrupter (GFCI)

If the circuit breaker does not trip, your next stop should be at the GFCI. This is itself a circuit breaker, much more sensitive because it is designed to prevent swimmers from getting an electric shock from the pool lights. If you don’t know where this switch is, try looking at your main panel box for your house, a sub-panel box near your pool filter device or an electrical outlet close to the pool.

Once you find it, check if the switch is tripped. It should have a test button, make sure the pool light switch is off, and press it. If the button pops, it means there is power up to this point and it’s on. If it doesn’t, press the reset button. If this button trips, you’ll need an electrician to find out what the problem is. If it holds, try your pool lights and see if they work.

Finding out the cause

Your light should come back on. If it doesn’t you may have a burned out bulb, but if it does, then what may be happening is that there is water in your light fixture. The light’s heat vaporizes the water which in turn makes the GFCI switch trip. This can also happen if there is humidity around the outlets that are on the same circuit as the GFCI; cover them up to keep this from happening.

Problems such as this are seldom included when calculating inground pool prices, but they’re a natural occurrence in pools. If you followed this guide you’ve probably encountered the problem. The question now is how to solve it. Well, if water in your light fixture is the problem, you will need to take it out and dry it, but there’s a set of steps for that procedure by itself. Make sure to research how to do it properly, so you can have your inground swimming pool lights back on in no time.
