I installed a Lutron dimmer in my dining room to dim my chandelier about 6 months ago. About a week ago the chandelier lights stopped coming on but the nightlight inside the dimmer was still working and my breaker wasn't tripped. I figured its a bad dimmer so I picked up a new one today. However when I installed it the chandelier is still not coming on. The new dimmer doesn't have a nightlight so I don't know if its getting power. I don't have a current tester. My switch box has 2 black wires and a ground. The ground is connected to my new dimmer and it doesn't matter if I switch the black wires on the dimmer. So either 1) My old switch broke and the new switch I bought is defective (crazy unlikely but technically possible) 2) ?????? I'll get a current tester tomorrow to check that the switch wires are seeing power. Any other thoughts in the meantime?
Check for power with a meter or wiggy. Sounds like you do not have power to the switch. It does not matter how the two black wires are connected.
Since you have two blacks in the switch box, it is most likely being fed from the light box in the ceiling. So, you may have to take down the light. Sorry but thats the way it goes.
Also, do not think you have a circuit if you read voltage at the switch when testing to ground. You very well may have an open neutral. Thats why you will need to follow the circuit back until you find the problem. Good luck.
Only had a minute today but I confirmed there is no voltage across the two black wires. I've flipped all my "light" breakers and none of the others are tripped.
does anything else not work?? I have seen circuit breakers be in the on position and still not allow any current flow. Get a wiggy or meter and test at the breaker, then test at the switch between each black wire and the ground. An easy test is to put the two wires in the switch box together, if the light lights, then the problem is the switch, if not look for an open hot or neutral wire. Beware if the ground wire is not hooked up at the panel you could read zero volts on the tester and still have a live wire in the box, BE CAREFUL!!!
.NOTE
It is not visible in the pic, but the nose of the tester is covered in plastic. So there is no metal to metal contact as in most testers. This non-contact sensor works because it detects the electrical field around a current carrying conductor.
This type if tester will find your fault without disconnecting the switch.
1) Remove the switch wall plate
2) Push slider up to max
3) With AC Power on check the two black wires
4) Both should indicate Pwr.
5) If Chandelier is OFF then check the other side of the wire nuts (Loose wirenut?)
6) If only one black wire shows PWR then input is OK but no output from switch
Look for two white wires joined with a wirenut in the switch box. Check this connection.
