Hello, I have a 2004 Optima. The breaker keeps tripping. I removed the front panels, rest the breaker, turned pump 2 on and it works fine. Now I turn pump 1 on and it trips the breaker. When I turned pump 1 on I noticed smoke coming from the circulation pump as it tripped. I took the cover off the back of the pump and it looks and smells like it's the capacitor. I disconnected the circulation pump, rest the breaker, turned pump 1&2 on and it's working fine. Do you think it's the circulation pump or could the heater be causing the problem? I didn't disconnect the heater but it's not tripping the breaker either when the circulation pump is disconnected. Thanks for your help
