| Assuming this is not a new but defective unit, the most likely reason is it got connected incorrectly.
Be sure, assuming there are only 3 wires at the outlet box, black, white, and bare or green, that the black connects to the brass screw labeled Line, the white connects to the silver screw labeled Line, and green or bare wire connects to green screw.
If there is an additional set of wires in the box, now here is where it gets tricky. one set of black and white from one cable must be live, hot, and must connect to the Line terminals as above, and the additional set must be dead that are feeding other outlets down stream in the circuit, and these get connected to the Load terminals.
If all of this is correct, then get back and we can go from there. |
