I have a Jandy JXI that's a little over a year old so out of warranty. The problem I'm seeing is it'll turn on, stay on for a few minutes, and then turn off. And repeat endlessly. It'll get the temp up eventually but takes forever. I had a tech come look at it and there's no codes so he spoke with Jandy who suggested a new Ignition Control Module. I've found one online and was wondering if it's just plug/play. Do I just swap out the old with a new one or is there some kind of programming that needs to happen?
