on lower board is there a blown fuse?
or do you have a meter to see if power is being delivered to top controller?

Aug 23 at 3:09 PMThe one and only fuse is good. There is 240 volt power to the circuit board. (checked with meter) I have disconnected the controller and the auxiliary controller, turn the power back with no response from any motors or hot tub functions There is no lights on the circuit board that indicate a problem or controller disconnect. When connected the controller has no lights or function. Bot***** *****ne - Power is getting to the main board but all functions are dead.

if power is direct to board....and fuse is ok...then you have a compromised circuit board. Have you checked the back of the board for hot spots or melt failures?

the back of the board looks normal
