I am replacing old Lutron switches with PD-6ANS moved from somewhere else. The blue wire is capped. The white wire is connected to the white in the box. The black wire is connected to the hot, and the red wire to the load. I tested and I see power on the black (hot) and the white ( neutral ), but nothing on the load. If I press the button to turn the light on, nothing happens. The small LED on the switch is not lit. The little tab at the bottom is pressed in. Pulling it out does nothing. I removed the switch and put the old one back and the lights worked. I put the PD-6ANS back and nothing. I tried another PD-6ANS ( also moved from another location ) and it does not work either. Both switches worked before being moved ( about 30 minutes in prior) . I have read a lot of threads here and nobody seems to add closure. So I have no idea how other folk solved this. Any ideas?
