itake it the light is still working if it is check the wireing from the pull switch to motor unless you have a neon live tester or volt meter thers nothing else you can check

SOURCE: Casablanca ceiling fan lights flicker out

here is solution for you.
instead of put all Fluorescent light bulb, put one incandescent bulb.
Dont' ask why but it works. (use 60w or above)

SOURCE: my casablanca fan/light wall switch only works

No . have this checked by a licensed professional it is more than likely bad switchs in the fixture but you can never be to careful with electricity

Light Operation: With the light in the off position press and hold the light button (do not let go). The lights should start at a dim setting and gradually get brighter and brighter. When they get to a setting you desire let go of the light button. To reduce the brightness of the light you must first turn the light off, and then press the light button and hold it in as described above. If the light is off, and you press the light button quickly to turn it on, the light will go back to the previous setting. So if you last had the light on the high setting, it will go back to the high setting, if you had the light at a lower setting it will turn back on to the lower setting. Keep in mind you can increase the light intensity at any time by pressing and holding the light button, but to decrease the light intensity, you must first turn the light off, and start over by pressing and holding in the light button.
Fan Operation: With the fan in the off position, press and hold the fan button (do not let go). The fan should start at a slower speed and get faster and faster. When the fan is at the speed you desire, let go of the fan button. To slow down the fan speed you must first turn the fan speeds off by pressing and releasing the fan button. If the fan speeds are off, and you press the fan button quickly to turn it on, the fan will go back to the previous setting. So if you last had the fan at the highest setting, it will go back to the high setting, if you had the fan at a lower setting it will turn back on to the lower setting. Keep in mind you can increase the fan speed at any time by pressing and holding the fan button, but to decrease the fan speed you must first turn the fan off, and start over by pressing and holding in the fan button.

SOURCE: I have a Casablanca ceiling/fan light with one

is the switch made to turn on and change the speed, the switch is acting up should chang the switch, but if you change the speed with the chains the wiring is loose up in the fan just need to take it down and tighten up the connections,good luck.
