QUESTION: I have a 520LM receiver with green program button hooked to a Commercial MJ-1211 Jackshaft Operator.<br /><br />My manual control has a Open, Close, Stop. I want the same functionality in my remote.<br /><br />Will this work with this set up? by Doug D 10/3/2015
STAFF ANSWER: You would need the 33 LM by Matthew O a
QUESTION: Will this work with a purple learn button? by None N 3/2/2014
ANSWER: The purple learn button means your garage door uses Security+ 315mhz technology. If your door has remote stop, close and open wireless capabilities, the Liftmaster 333LM should operate all three functions once programmed.<br /><br />Many garages have stop, close and open hard-wired functions only. That means the inside three-button door opener, usually attached to the wall, is directly wired to the door opener. Your 333LM will still work, but only for opening the door. <br /><br />In summary, if your garage door has remote stop, close and open wireless capabilities, all three buttons on your 333LM will work. If your garage door doesn't have three-way wireless capabilities, your 333LM will only open the door. In my case, I have two garage doors, so I use the red button to open one door and the green button to open the other one. by C E a
