Hello, I'm having an issue where I'm unable to fire my heating element with the simple wiring diagram below. It's a 3-wire, 220v/20a circuit...ground is not shown. When I fire up the system, the PID turns on and is set to manual mode to run at 100% The RTD probe is hooked up as well. The OUT indicator is displayed. Also, the LED on the 40a SSR is on, but no heat is generated at the 3500W element. If I connect the wires 1 & 2 and bypass the SSR, the element fires up, which would indicate to me that the SSR isn't working. I ordered and installed a new SSR, but had the same results. While it's possible that both SSRs are bad, it seems unlikely. Does anyone have an idea what might be wrong here? Thanks in advance for any feedback! -David
