The light that blinks really would be the lightbulbs on the machine ,to programm the remote you must first press the smart button on the machine and then press the button that you would like to program on the remote , now you watch for the lightbulbs to click off and then on again , this is the machines way of saying i accepted the code , check your manual for the location of the smart button ,some machines have them on the left for two light units that are side mount or some of the units also have them on the rear of the machine ,theese are usually brightly colored square plastic buttons , it will also have a small led light beside it that blinks from time to time , this would be the rolling code technoledgy of todays more modern openers , You can also remove the plastic light covers to see this button ,remember wherever the bell wires and infrared wires from the senser go ,That will be the location of the smart button ,because that would be the mother board where all the functions are performed , Hopefully i was able to help you and i Thank you for the question ,now get crackin and program that remote Sincerly Glenn Mayer

Hi I have a chamberlin lift master Professional formula 1 garage door opener and the lights use to time out but now they stay on.

The relay that controls the lights is most likely bad. This is a unfortunately a common problem after electrical storms.

Liftmaster Professional and Clicker Programming Problems

The Security+ system is a rolling code system and is digital, so it will work with the Homelink in vehicles and with the remote control units that come with the opener. Also with new remotes that are purchased specifically for that opener. Your "clickers" require specific instructions and you need to use the Smart Learn function in order to use them with this opener. In addition, check the Brand Switch settings to be sure they apply to your opener, and the correct Smart Button color on the opener. Read carefully to determine whether you need to set ANY dip switches at all or can you just set them all to off depending on your opener? Check the instructions carefully. Here's a link to the page where you can download a copy of the Clicker instructions if you don't already have it:

Need to program my chamberlain #953CB from a working gate opener

the chamberlin remote only work with a chamberlin reciever, if you have this it will be a silver box that looks like diamond plate material inside you operator, take of the front cover on this box and you will see a black button that says program push and hold this button down then push your remote button down while holding it close to the box you will see a yellow led flash and then it is set. if you only have a single button remote you will only be able to set it to one operator.
