When we rehabbed our kitchen in January, we installed LED recessed lights and a Maestro MALV-600 dimmer with MA-R slave. The system has worked very well until this morning when I was unable to turn the lights off. The lower three green lights on the MALV were showing and all the recessed lights worked but they could not be dimmed or brightened and they could not be turned off. I turned off the circuit breaker for about 10 seconds. Everything works as usual now. I would very much like to know what may have gone wrong and if there is a permanent solution. Thanks.
