Well the specific issue here, is availability of parts.

Your topside is working.

Your board isn't.

I wouldn't waste money on a topside especially when a board isn't available. It's time to replace both with a good generic drop in replacement control system and then you'll be done with it.

Thanks for your help pageup. How do I know what circuit board will be compatible for what I am taking out. If they dont make my board anymore what a good brand to go with. Can I just buy the board and get it to work or do I need to buy the whole spa pac

There is no compatible board available.

Pack is the best option anyway, besides you get a warranty too.
