Sensor Classic Stuck Dimmers

Hello everyone,

I have two racks controlled by Sensor Classic SR48 CEM's. One of the CEM's has 12 dimmers that are stuck on and I have not been able to figure out why. If I swap it to the other rack, the same 12 dimmers are stuck on, but in the opposite rack.

Does anyone have any idea what may be causing this?

I have already tried re-setting the CEM in both racks, I've tried disconnecting the DMX and re-setting, nothing I have tried has helped.

I'm getting into desperation mode as we are about to enter our busy season. Any suggestions would be greatly appreciated. Thank you!

Sounds like a power cube issue (https://shop.etcconnect.com/q141-dimmer-module-power-cube-20a/) If they go bad the dimmers can stay on, stay off, or flicker. I'd call ETC to 100% confirm, but that's what it sounds like to me if it's following the dimmer cards.

Thank you for the suggestion! I believe the problem has something more to do with the CEM itself than the separate dimmer modules. To clarify, the dimmer modules in Rack A are stuck in a specific location in the rack. If I swap the CEM from Rack A to Rack B, the dimmer modules in Rack B are stuck in the same locations as Rack A, but not the same specific dimmers. Does that make sense? I will call ETC and ask about the power cubes either way.

Yes, you swapped CEM's, not dimmer cards as I assumed. A call to ETC would be best.
