Now that I've read a little more. I now know better than to plug 100ft extension cord and circular saw into the same outlet as my Blue Haven /Hayward pool controller. After working on my shed, I got the CHECK SYSTEM NO CELL POWER ERROR. I wasnt terribly worried because I've had what I thought was the same error before, fixed with a new 20A fuse. Well Google tells me that was error 1, I have 2, replace PCB.
I took the PCB off, and just like many other posts, burn spot at the relay.
But I also noticed a little burn under a big capacitor, and looking closer at the cap, it has 2 sticky domes on it. I guess I'll try soldering the relay. Any thoughts on the cap?
