I recently changed the bulbs in my Dining Room ceiling light/fan to CFLs. To start with everything was OK. Then problems started developing and the lights would only come on if the fan was on. Now neither the lights or fan works, even when I put the old incandescent bulbs back in. Weirdly, problems have occurred elsewhere on the lighting circuit - the fluorescent tube in the garage has stopped working, and most bizarrely the LEDs in the study light are slightly on all the time, even when the switch is off! Other rooms on the same circuit (lounge and utility) are working OK.
My first suspicion is that something in the ceiling fan has blown. Any ideas?
