What is the make and model of your spa? Once the display goes blank but the buttons all work you need to replace the topside. The thermostat is controlled thru the topside so this may be why it is not stopping at set temp.

All thermostats have a 2 degree fluctuation in them and if it is very warm where you live that could also be causing the rise.
