Ask for help about the remote control fan chandelier remote control is broken, how to solve it

Analysis and maintenance: This phenomenon shows that the remote control is normal as a whole, and the reason why individual keys do not work is that the key circuit contacts cannot be effectively conducted. Most of the contacts on the circuit board in the remote control are dirty, so that the contact resistance increases or can not be connected, you can use cotton dipped in anhydrous alcohol to wipe the carbon film contacts, but not too hard, in order to prevent the carbon film layer from wearing or falling off. Aging or wear of conductive rubber can also cause individual keys to not work. In this case, just stick the tin foil (preferably aluminum foil sticker) in the box on the conductive rubber contact points. If the above methods cannot restore the remote control to normal operation, you should check whether there are cracks or poor contact between the keying signal input and output end of the integrated block and the contact line, especially the connection between the carbon film contact and the electrical circuit, and replace the integrated block if necessary.
