EDIT: Nevermind, I figured it out. I just rewired the switches to that one isn't even connected and the other is connected properly and it works great.
My house was built back in the 70's and has had some renovations but we are new owners. I am trying to replace the ceiling fan (something I have done multiple times previously with no issues) but I hit a bit of a snag due to the dual switch. In this room there is a switch for the fan and another for the light. The fan I am installing only has black, white, and ground wires because it is controlled via a remote control. In the ceiling, there are only three wires, white, black, and ground. Apparently these are not functioning as I would imagine due to the dual switch since when I installed things normally (white to white, black to black, green to ground) nothing happened.
I tried installing just a basic light that I have that only has white and black wires to diagnose the issue and finally I got it to turn on when I put the white to white and black to the ground. This makes me guess whoever wired the switches did so in a way that the ground wire is essentially being used as a neutral which I imagine is not the proper way to do things. Since I have no need for a dual switch I assume it would be best to just go back to a single but this is about the extent of my electrician knowledge and it isn't something I want to just guess with.
Here are some pictures of the switches, I will explain everything that is happening with the wires below but sometimes a picture is a lot better.
So the three wires coming from the ceiling are coming in on the right side. The black ceiling wire is going to the top right spot on the right switch. The white ceiling wire is going to the top right spot on the left switch. The ceiling ground is connected to two white wires going behind the left switch (goes to a spot where one says + and the other says N).
The bottom right spots on both switches are connected by a small black wire. On the bottom right spot of the right switch there is another black wire going to two other black wires and a red one that go behind the left switch same as the two white wires that accompany the ground from the ceiling.
Any ideas? Can I install the fan as is or is that a bad situation? Is the best solution to just get rid of one switch and convert things to how it should be setup with one switch in the first place? If so how would I correct the wiring?
