Common Cause of Ceiling Fan Light Problems

The most common cause of ceiling fan lights that strobe like this is due to wrong size light bulbs, more specifically, the light bulb size may be too large, so I would check this first and make sure they are the recommended size.

Additional Possibilities with Ceiling Fan Light Strobe
Because the lights strobe when the remote is used to turn them off the remote control module may not be wired correctly – so double check the wire connections and make sure they are correct according to the wiring diagram and instructions which were provided with the remote control units.

Are you using LED light bulbs? If so make sure the remote control unit is fully compatible with LED lights, and make sure the LED lights are Dimmable.

Check the Ceiling Fan Remote Control
Are the remote control modules addressed individually?
If the remote modules are set to the same address this could cause confusion with other modules in the same location. Generally this is not a problem, but it would depend on the specific control modules you have.
