The LED on a Victor is yellow when neutral and will only go green or red as it gets near full voltage. For anything between neutral and full output, the LED will be off. This is normal operation.

Do you have the Victor fans wired to the power input? If so, you can watch whether the fans stop to see whether or not the Victor is still receiving power. A too-high load from the motors could be tripping the circuit breaker.
