Lights dim after being on for a little while...help!!!!

Help!! I have a ceiling fan light combo in the living room and the lights have started dimming after being on for about 30 seconds.  It doesn't matter what type of bulb we put in, it always dims.  Any ideas on what could be causing this? I don't want to replace the ceiling fan if this is an easy fix.

That's kind of an interesting problem.  How is the fan and it's light controlled?  Switch(es) on the wall or is there a remote in it as well?  This is a new problem and the fan/light worked fine for some period of time before the dimming started?  When you say different types of bulbs, does that include ordinary incandescent bulbs or CFLs and LEDs?  If incandescent, what number and wattage of bulb have you been using?

Hey jnmessmer!

Unusual when it happens to you, but actually fairly common.

Your fan and light are assembled in several stages.

If you're "handy," start by simply operating all of the switches through their cycles.

Pay particular attention that each switch clicks into the next position ... switches sometimes get stuck between toggles.

Don't overlook the switches on the fan housing.

NEXT:
Pull-chain switches are known to break and are fairly easy to replace.

Remove the light kit, disconnect each wire nut or connection and reconnect each and test again.

If the pull-chain switch sticks at all, replace the switch and test again.

If you're lucky, one of these tests will identify the problem.

If you haven't discovered the problem, it will be necessary to remove the beauty ring from the ceiling to access the connections inside the ceiling electrical box.

Disconnect and reconnect each and test again.

Hopefully, you'll have found the problem and your lights will work fine.

Once you've tested all of the connections, be prepared to replace the fan.

It is really just a process of elimination.

NOTE:
Light bulbs are very different today.

In particular, energy saving bulbs can be fickle when used in old school lights intended for incandescent bulbs.

Check to determine that you have the manufacturers recommended bulbs installed.

SAFETY FIRST:
Always shut off the breaker while handling electrical connections.
