Have an inground pool with a spa. Sta-rite heater with in-house and a spa side controls. Opened pool for the season and everything looked fine. Sta-rite heater Aux-1 controls pool lights to pool and spa. Aux-2 controls spa blower. When I press the Aux-1 it lights up green on heater but nothing happens. Same as the Aux-2 button, green light comes on but nothing happens. I did replace GFCI on the side of breaker box but did not solve the problem. I noticed a "clicking" noise coming from the electrical box every time the Aux-1 and Aux-2 buttons are pressed. It seems to be coming from the relay switches in electrical box. Any thoughts? Any Suggestions? Thanks in advance.
