Liftmaster 1280 LMC Motion Detector Garage Opener Push Button Pad Not Working

The remote in the car works, the wall mount unit outside the garage works, but the motion detector push button pad does not work to close the garage door and the 2 green lights on this unit are continually flashing.

    We purchased a new push button pad for inside the garage and everything is back in working order. The old unit was about 8 years old and there was obviously a problem with the circuit board inside this unit.

    Hi there

    I am here to help.....honest.

    I never got a reply from you,



    I thought it only fair to answer the questions before rating the solution,



    The questions I have asked were to become better informed about your problem.Not to guess,

    Security is very important for ME too,

    I deal dierctly with the Suppliers in New Zealand,

    Great Company Good Products.

    If their info is incorrect then they definately need to know.



    I assume you could not reprogram that is a normal result of the faulty printed pcb board inside the unit and the only solution was the purchase of the new unit,

    Changing the battery would have shown you this unless it was a hard wired unit without a battery then the main control unit would have had fault too ,



    I thank you for your time and would like you to reconsider rating the solution thanks

I have a liftmaster formula 1 1280R opener that works fine from the wall mount but all of a sudden both remotes and the built-in remote in my car stopped working. It is not the batteries in the remotes. ...


The motor/control unit may have gotten reset. It needs to relearn the codes transmitted by the remotes.

MIne has a "learn" button on the control unit. Press and hold, then press the button on the remote. Lights will flash indicating it has received and stored the code. Release button.

Check to see if the remote works now. If so, all three should be working. If not, dig up your manuals.

Garage door only opens sometimes with remotes< and exterior keypad. always works with wall mount button.


Check the light bulbs in the opener. Newer fluorescent or LED bulbs can generate enough radio frequency interference that the normal signal levels from the remote will be inadequate.
Of course, make sure the remote batteries are fresh.

You need to reprogram the remotes by briefly pushing the learn button on the garage door opener until it flashes once, then release the button on the garage door opener.

Now press the remote button once until you hear the garage door opener click, now press the remote button once again and the remote should be programmed to work for that garage door opener.

DO NOT press and hold the garage door opener learn button for more than 10 seconds or you'll erase all programs and have to relearn all the remotes, including your car ones.

Hope you found this very helpful and best regards.

Check wiring back to unit to make sure it's not shorted or broken. You can also reset the garage door opener by unplugging it for a few minutes and plugging it back in.
