I have a few DZMX1-1LZ dimmers in my house and, for the most part, they work great. However, I notice a random flicker or blink once in a while. I have three of them in the same gang box, neutral wires installed and all. One controls recessed lights (4x Philips LED bulbs), another controls a light fixture (3x Cree LED bulbs), and the last one controls a lamp in our patio (1x Cree LED bulb). Each set of lights will have a random flicker at different times. They all run off the same neutral wire, so I'm not sure what the issue is. I may swap the bulbs in the light fixture to incandescent to see if it alleviates the issue. Anyone have any ideas?
