Thanks for all the advice. I’ll take the board out today and see what kind of condition it is in. The front, from what I can see looks really clean. But I will report back. 
Worst case I will likely replace the whole pack. As mine looks to be about 13 years old. 
If I do replace the whole heating  pack, any recommendations on which would be a good easy fit? Or maybe which brand/ model to avoid? 
 

thanks for all the help

When I took out the original board I inspected it pretty thoroughly with a magnifier.  I did not find any components damaged.

Ordered and installed new board (Balboa 53834-04 = $340) and its all working again.  Make sure you configure the wires for 120 or 240 components when installing.  I'm pretty sure an electrical surge or brown out toasted it.  I also changed the heating element while I was there.

BTW the SNB error was not due to sensor A or B.  It was a board issue.

That was my thought so I tried...

• Switching the hi/lo temp sensors
• Unplugging them completely

These both resulted in the same Snb error.

It looks like the replacement trail look like this:

• 54301-04 (original)
• 54302-04 (discontinued)
• 53834-04 (current replacement option)

Balboa 54301-04  460  

240v
Stopped working a few days ago.  Only error I can get is "snb".  

Things I have checked.

• No blockage and filter has been removed.
• Hi/Lo sensor unplugged and rebooted to check if it was problem.
• Checked all connections are secure.
• No water damage.
• Checked heater resistance and falls within range.  
• Unplugged pumps and reset to check if they were a problem.
• Checked fuses.

Food for thought.  This happened when the hurricane remnants came through mid-north-carolina last week (10/29).  I wonder if the board got fried from a surge or brown out with the electricity.  

Any help would be great.  If you have any replacement options for a new board that would be great too.
