I installed this MACL-LFQ dimmer a few months ago to replace a Lutron L2-LFSQ because one of the tabs had broken off. I used this newer, more expensive model because we wanted to use LED bulbs instead of the incandescents.The wiring was simple since it was already replacing another fan/light switch, and it worked fine for a couple months.Recently, after turning off the light, hitting the switch again doesn't turn it back on. Sometimes, the very top (light) and bottom (fan) LEDs flash, and if I push the light switch a couple more times, the lights come on.Other times, the bottom three LEDs on the light switch flash and the switch is completely unresponsive until I pull out the FASS (before I discovered that switch, I had to turn off the breaker to that room).Is this dimmer defective? Thanks for your help!
