A light/fan in my son's room stopped working and I am having trouble figuring out how to fix it. First I replaced the bulb. Then I looked online to see if I could find any help and read about how remote control things sometimes have stopped working. I took out the remote control box between the wires from the ceiling and the wires from the fan/light and attached reattached the wires without the remote. It still didn't work. I then tested to see where I have power with a voltage tester and found I have power in the lightswitch but do not have power in the ceiling electrical. What step do I take next?
