Switch or something else? Please Help
 
I have a wall mounted single pole decora switch that operates the light on my ceiling fan for the master bedroom. There is also a separate switch for the operation of the fan. Both switches are in a duplex box. Here is my problem. When I turn the switch on, the light comes on for only an instant, then goes out. If I turn the switch back off then back to on, the light works perfectly. I replaced the switch with a brand new switch, same problem. I rewired the switch to the screw terminals and not the clamp ons when I replaced the switch, no fix. I removed both switches from the box and checked all of the connections, no fix. I rewired all of the receptacles on the circuit to the screw terminals instead of the clamp ons, no fix. I checked the wires in the ceiling fan box. Still have the same problem. What am I missing?

Remove both wires from the light switch and wire nut them together. What is the result?

Or you may have power coming into the switch location so something like this:

Will try tonight. Thanks

I suspect the issue is with the fan itself. To prove, swap the fan and light wiring in the ceiling box.

Did you do anything before the problem showed up ? ( e.g. change from incandescent bulbs to CFL's.)
Regardless of the answer above, what bulbs are in it now ?

How old is the fan ? Was it purchased before or after 1/1/09 ?

rjniles: I did what you recommended and swapped the wires in the ceiling box. The same thing happened on the light. I am guessing that is telling me that the fan is bad. Is that correct?

Oso954: The fan is just over two years old. It has 2 candelabra bulbs in it.

You mean the light had the same issues on the new switch. Pull the light kit off the fan and see if there are any electronic devices in the light circuit.

There appears to be some type of black plastic box in the light kit. I don't know what this does. Everything else are switches and wires

Some of the ceiling fans luminaires do have watt limiter to limit the amout of max wattage it can be used in the luminaire.

What type of light bulb you have ?

Indentscent or CFL or LED and what wattage it is ?

Merci,
Marc

Does your black plastic box look something like this ?
If yes, it is a wattage limiter.
If you have CFL's in there, they are probably exacerbating the problem. Try running some incandescents and see what happens.

If you have incandescents in it, the wattage limiter has gone bad. I would call the MFG. They have been having problems with them. Some MFG's have been shipping replacement light kits even when warranty has expired.
