Swimming pool lights aren't working!?

By any chance are they on a timer? In order to not run the lights during the day pool installers will sometimes run its lighting circuits through the timer/s on its own zone. If you have had a power outage and the timers are analog their time gets offset by however long the power is off. If it has gone out a few times it is accumulative. Try to switch the bypass switch at the bottom. Probably a silver lever with arrows. I'll put this on clipboard to watch for any updates, now I'm curious. Let me know if it doesn't work. Is there a chance that all lights are burned out? They usually wont go at once unless there is an issue.

PS the timers are 6" X 8" gray cans, they will have a silver tab going through the door with a hole in it for locking the covers. Once opened you will find a large yellow dial. By pulling it slightly to disengage turn it to the correct time per setting on the dial. Do not move the pins they are preset times and zones.

By the way because you can control the two separate applications of light {hot tub/pool} from two separate locations {two light switches} and do different functions {different color changes} does not necessarily mean that they are separate circuits. It means that one lighting circuit has been split between two switches for a power source. Then a device is installed at each location tub/pool to make the "switch leg" portion do different things, after the switch. So you still may be looking for one source of power. While your out at the pool mechanical area look for another GFI running maybe those timers that may be where its at if not in the timers itself.

So by the time you are through you would have checked:

1)The Main {sometimes has a set of branch circuits for outdoor use contained under the main breaker in a small sub panel look for a door or latch. This is where the main sub feed to your pool/hot tub should be as well, along with the breaker for the sub-panel inside your house. If there is more than two {2} pole breakers.........

[{50/2-pool} and a {125/2-sub panel}or{100/2 sub panel} will be the amperage/pole of the breakers]

................then find out where the other/s go. You may have a small service sub-panel located somewhere for landscape lighting or alike.

2)The breakers in your the sub-panel of your house in case they pulled an unconventional circuit from a closer source. Check while your there for any mini breakers, they are thin half sized breakers that you can fit two in place of one thicker breaker. Make sure that one of these will not move more freely than the others. As well as check for any breakers that just don't look the same as the rest. MINNIE'S! I'd like to line the guy who thought that one up and put him in front of a firing squad right beside the yahoo that gave the OK to use aluminum wiring.

3)The sub panel at the pool mechanical area that runs all of the pools pumps and stuff. Yeah check for Minni's there too.

4) The GFI'S outside of house, by the pool, bathrooms, kitchen, garage, and pool mechanical area.

5) The timers in the pools mechanical area making sure that the timers themselves have not lost power by hitting the bypass switch to turn whatever it runs on. Usually a chemical or treatment pump that is needed the same time everyday.,.Do you know of another place in the house that will have a timer? Check there too.

6) The dogs bed...........................WHAT? that where I find most of the stuff that come up missing lol. My 90lb puppy loves to store things away for me. Why just yesterday he put my belt in storage. It took 2 days of continuously pulling up my pants before I remembered my personal storage area.

If you have not found the issue after that then its time to get familiar with a multi meter tester or the yellow pages. Let me know I can help with one of those lol

Good Luck, They say if you love what you do you never have to work a day in your life.....it is true I really dig this stuff, been doing it since I was 10, and still get jazzed when faced with something like this.

Swimming Pool Light Transformer

To continue where Bob left off.

If the transformer is putting out power the next step is to locate the pool light junction box near the light. It should be close by. Pool lights come with a 25' cord standard, but 50' is available. The junction box may be a 6" round black plastic style or a 2"x 4" gray metal or plastic box. Check for 12-14 volts there. If it is 2"x 4" then there is a good chance the splices are badly corroded. For some unknown reason installers often leave the wire nuts facing down and as result water collects in them and the connections corrode. If all is good there you will need to remove the pool light housing and check the bulb. In all likely hood you have a submersible type fixture. Reach down and locate the Phillips head screw holding the trim ring in place. Be sure to use the correct size screw driver, #2 I believe, and lots of pressure on it as you don't want to round the head off. Once it is out the housing should lift up and out. The cord will belong enough to reach the pool deck. Then remove the screws holding the glass in place. If you have a continuity tester check the filament of the bulb. Verify the wattage of the lamp (300 or 500 watts) as the transformer is sized accordingly.

When you have a new bulb installed You can turn it on MOMENTARILY to verify it works BUT ONLY for a moment. IT Will burn up if left on for even a few seconds as it gets hot fast. When it is submersed it stays cool. Then carefully coil the cord back around the housing as you reinstall it.

On 2 occasions I have had to get in the pool in order to remove the screw or remove the housing.

Good luck with it.

Swimming pool lights aren't working!?

Tonight my swimming pool lights wont turn on :(. There is two light switches, one for the hot tub, one for the pool. They're on separate circuits - I can control them separately (make them different colors from each other.) The GFCI breaker on the garage breaker panel for the light...

On the outside of the house near your pool pump is square or rectangular box, in there is the transformer for the lights. Pool lights run on low voltage and the transformer changes it from line voltage, usually 120ac, to 12 volts. open the box and be sure it is getting line power from the house.

If it is getting power you then need to check the output side, it should read 12 volts. If it is putting out power the lamp in the pool light is no good.

Check your "breaker box" switch on and off to be sure each is working! If that doesn't help - your lights may have burned out. (breaker box is located on outside of your home - look up in the sky for ELECTRIC LINES coming to your home - from the back yard)

Step One: Check to see if light has burned out.

Step Two: Replace

Be sure you have checked everything a new. Then, if not working, call an electrician.

Maybe the lights burned out.
