Installed new light fixture and now apparently have a switch loop because the switch (just one) does not turn the light off.

Ceiling
2 blacks joined, 1 white, and a red.

Fixture
1 black, 1 white, and 1 open wire

Hi Jeff,


Ceiling
2 blacks joined, 1 white, and a red.
Bet there are two white wires.


Fixture
1 black, 1 white, and 1 open wire
What is an open wire? Do you mean bare?

Pull the switch, there you will probably find two white wires connected together, two black wires connected together and connected to the switch. You should also find a red connected to the switch.

If so, connect the white of the fixture to the whites of the ceiling, connect black to the red of the ceiling. Connect all bare wires together.
