Hi Everyone, I am new to TFP. I am a relatively new pool owner (2 years). We turned on our spa last night and the service heater light immediately turned on. The spa does not heat. Any advice?

Welcome to TFP.
If you are getting a "Service Heater" LED, then you will have an error LED on the control board or the Fenwal of the 5 button heaters. Check the diagnostic LEDs or the Fenwal box LED for blinks.
Diagnostic LEDs are on the back of the older 5 button non-connected Pentair MasterTemp heater board. The 6 button RS-485 Connected Heater displays the diagnostics on the heater display or IntelliCenter display.
