I have had a problem for months where I couldn't turn off my fan when the light was on. I knew that I could have gone and bought a new switch box and fix it but today I decided to tinker with it and fix it by myself.
I unscrewed everything on the light/ceiling fixture, there I saw that a tan wire was disconnected with some copper showing. I disregard that and simple gave the fan switch a few pulls and unconnected and reconnected the light bulb. After reconnecting everything, the problem is fixed. The fan doesn't run when my light is on, which I am grateful for. However I noticed a peculiar problem. There is an orange glow coming from where the chain to turn off the light switch is. I don't know if it has always been that way or it happened after I tinkered with it. Is this a safety hazard or nothing to worry about. There is no heat coming from this "orange" glow.
I think it is just the light from the bulb shining through the opening in the switch. You need to investigate more with dome off the fixture to confirm there is not some arcing or something else going on.
