if it's a blown cap, is that something that can be replaced individually?
Is that what the spa is doing, restarting constantly?
you can probally tell by looking at it if its bad. I think it is a 3300 mfd right above the trans plug on the board, the top will be domed and leaking.
Yes it can be repaired. But, if you don't know what a capacitor is or you don't have any experience in soldering pcbs, I would send it out to be repaired or have the board replaced.
i'll check it out tomorrow. I do have some electronics experience and I'm not bad with a soldering iron. hey, a capacitor is cheap. might be worth a shot. if i trash the board i'll still end up replacing it. Thanks for the help!
