I have a remote-controlled ceiling fan and light. I don't run the fan, but when I turn the light on sometimes it will stay on for a long time then just go off by itself. I have tried both kinds of bulbs, but neither works. What causes this problem. Do I have to replace the ceiling fan and light, or can it be fixed?
I had a ceiling fan where the light turned off after it heated up, it turns out that the contact that the bulb screws into lost contact due to the expansion of the metal due to the heat. You could try bending the contact out a bit to see if that helps. Clean it as well while you're at it. Make sure the power to the light is off so you don't get a shock.
Another possibility is that the radio control is being activated by interference or someone else using a remote on the same frequency. Many devices like doorbells and garage door remotes use the same radio technology, so changing the radio channel your light uses may fix the problem. Your manual should show how to do that.
