I need to replace the GLX-PCB-MAIN board on my Hayward Goldline Aqualogic PS-8. GOt a few quotes and they want anywhere between 700-1000 dollars to do it but I can find the part online for less than $400. Has anyone replaced a main board and is it simple enough, i.e. pop and swap...or will I need to reprogram it all? I am fairly handy and am an engineer by trade so I wouldn't think it is above my head but wanted to reach out here for some advice first. Thanks!
