calsparepair Posted March 17, 2010 Report Share Posted March 17, 2010 You can find Cal Spa owners manuals going back to about the 1980's at: www.calspas.com/manuals You won't find much in the way of schematics. The PS4 was pretty straight forward and used standard HVAC components. You should be able to manually trace the wires to determine if anything is wrong.

Have opened it up and there is a diagram of sorts but may depend upon your definition of "schematic". It is so small that I cannot copy it as I have tried with my digital camera and many parts won't stay in focus. It is slightly rumpled and tightly glued to the back of the metal front panel and is not removable. Maybe I can help? Quote Link to comment Share on other sites More sharing options...

Start your own thread. Include good pics of the control box guts. Maybe we can help that way, since nobody seems to have the diagram. Some old systems kept it in a sticky bag on the back of the box. Check there. Quote Link to comment Share on other sites More sharing options...
