Before I took the dimmer out to check the wiring, I checked the bulbs (which are LED bulbs, for what it's worth) since that's the only thing that changed recently. I noticed that the socket for one was very close to touching the metal housing around it. I touched the bulb and it sparked and the dimmer went out, obviously shorting out, but the breaker did not trip. I assume that when the bulb was replaced, it was tightened enough to move the socket too close to its housing. Now the dimmer doesn't work at all -- no green LEDs light up at all. I took it out and replaced it with a spare Maestro MA-600 that I had. The chandelier works fine now. Did the RRD-PRO get fried? Is it possible to test the RRD-PRO, with a multimeter for example, to see if it's dead without putting it into another circuit to test it?Thanks!
