Make sure the batteries are good in it. Try reprogramming it. Find the colored learn button on the back press it and then press the button on the remote. The light bulb will flash once to tell you it is programmed. If this does not work you will need either an external receiver or a new logic board. If you get an external receiver you will need the remotes to match. Thanks BB
