I have a Leviton NSI DS12-12 dimmer at my church that's been in service for about 6 months. This week it shut off and won't reset. The display is blank and the over-temp light is flashing. I've tried shutting off the power, pushing various buttons but can't get it to reset. Its in a closet that is not air conditioned but shouldn't be getting above the 104 degree temp that the manual says. Its the only thing in the rack with several inches of space above and below. When it shut down was mid-week with no one in the building. The loads are all within range and I only have 4 channels used at that.
There seems to be very little info out there for troubleshooting. I'm planning to take the cover out and blow it out but can't see how it should be getting dust clogged based on being in a restricted area and only in use once or twice a week for a few hours at a time.
Any help is appreciated. I need to get the house lights on for next weeks' service! Thanks!
