If your Intermatic Pool Timer has stopped working, swapping it out is pretty easy. Here I show you how to change a T104M 240 Volt (208-277 Volt) Model. If at any time you feel like it is too dangerous or you are unsure call a Pool Service Tech or an Electrician. But as you can see from the video this is pretty easy.
Before you change it out, test it by replacing the "on" and "off" trippers. That maybe all that it needs as those wear out and it appears the timer isn't working. If you change those and the timer still is not working then it is probably bad.
One thing to note is to make sure the power is completely off at the Main Breaker. A kill switch or a Sub Panel may not turn off the power to the timer completely. So make sure all power is off from the Main Breaker.
I like to mark the wires with tape as I do this job as not to lose track and make a wiring mistake. If you wire the timer incorrectly it won't work and may short out the breaker. So this is an important and crucial step. With a 240V model there are sometimes a lot of wires so marking them is smart.
Then it is just a matter of swapping out the wires for each wire set. Pretty easy. On this 240 V timer there are two Line Wires (Line 1 and Line 3) and two Load Wires (Line 2 & Line 4). If you are changing timer mechanism from another brand like G.E. Or Paragon Timer make sure you line up the Load and Line wires correctly. Refer to the schematic inside the old timer so you know which wires are which. You know that the Intermatic wire order so it is just a matter of matching the wires up as the other timer may not have the wires all in the same location as the Intermatic one here.
You can simply buy the Timer Mechanism without the box if you are not replacing the box or if it goes in a panel like the one in the video.At the end of the video I show you how to get the timer out of a box type set up and one screwed in with Torx screws.
