Thanks for the response but no it is not locked

I would first check to see if the control panel is locked. Should be an Icon displayed if it is. Refer to owners manual to turn off. Should have a temp lock and a panel lock...

I have a 1998 sundance spa, control panel model 850 dual pump, the heater works, the ozone works, but the control panel is frozen, display works but I cannot turn pumps on, or change temp settings. I tried shutting off power, and disconnected control panel from circuit board. Any way to confirm control panel before I spend money for new one.
