    Chamberlain 1150lm garage door opener
    Our chamberlain 1150lm garage door opener is opening and closing on its' own throughout the day and night. How do I clear the existing codes on the unit and reprogram the remotes to a new code?

    WOW! Today I have the exact problem you do. So far I haven't found the answer. I did find the following that is supposed to work. It didn't for me but it might for you, here is the web page. Please post if you find the answer, I will do the same. http://www.liftmaster.com/consumerweb/pdfdocs/114A1763.pdf

    You may want to start by clearing all codes, then programming what you have, if it continues, disconnect the receiver to see it is it picking up signals. Then physicall follow wiring to pushbutton and look for a possible short/intermittent connection.

    If the door is in the up position, maybe the eye is blocked. Have you tried readjusting the limits?

    Startmando - How do you reset the codes on the 1150LM opener? Not the remote but the opener. Thank you!
