I have these remote control fans and lights throughout my house, all are working fine, except one. The remote is fine, if I change the numbers it works in other rooms. Now does anyone know HOW CAN I DISCONNECT REMOTE AND USE IT WITHOUT REMOTE. ANY RESPONSE WILL BE APPRECIATED.

You need to take ceiling fan down from ceiling , there should be a box that you can disconnect so you can use fan/light without remote

Does it have pullchains?
