Hello all
I've been a member for a while and have learned a lot from the forums on here. I am still a novice when it comes to maintaining an SWG pool so I come here whenever I have the smallest of issues. So, thanks to y'all for sharing your knowledge and teaching guys like me.
Now to the issue on hand; I first noticed that my SWG stopped working about 3 months back (May '24). After reading through forums and following the Hayward SWG Troubleshooting guide I found that my Thermistor was bad. I bought the thermistor and replaced it on the PCB (watched a few videos). Next, I notice about a month ago (July '24) that I had no power light at all. Once again, I read through the troubleshooting guide and this time I noticed visible damage on the ORIGINAL PCB. I ordered a generic PCB off Amazon. I also noticed some black marks on my Thermostat and ordered a new one as well even though my old thermostat showed resitance numbers within the limits. I replaced both PCB and transformer and ran my SWG for about a week just fine and noticed no power LED again. I ran the tests again per the guide and noticed no resistance on the NEW Transformer. I put back my old transformer and turned on the SWG and heard a pop right away. I opened the panel to my SWG and noticed that my brand new PCB is fried.
At this point, I am unsure of what's going on. Any help is much appreciated. I have had the system for over 7 years now but now I am leaning towards not running the pool on SWG system
