On the CRJ there is a Red Light warning for Bleed leaks, but that comes with a "Bleed air duct" aural warning. There's no memory (recall) item, and the QRH leaves you with an idling engine, and no further guidance. (Been there).
On the Boeing, which we mostly seem to be talking about, once you have started into the memory items, you are committed. Why wouldn't you? (Been there, too).
Even if you just get a short warning (lights and/or bell) that goes away before you start the drill, I would think carefully before disregarding it.
