What is the problem if a measurement across the solid-state relay terminals is normal, but a load is not operating?

Explanation:
When the solid-state relay appears to be switching normally (the measurement across its terminals reads as expected) but the load does not run, the issue is in the load path rather than the switch. The SSR is delivering current, so the fault isn’t the relay itself or the control signal. The problem lies with the load or its wiring being open, damaged, or disconnected. Check that the load is intact, the wiring to the load is continuous and properly connected, any fuses or protective devices in the load circuit are intact, and that the load is correctly powered at the proper voltage/current. In short, the load circuit path after the SSR is the likely failure point.
