how do you program the 971LM transmitter to liftmaster 850LM receiver

Really easy setup. There is a button on the remote and a button on the receiver. Press button on remote to put it into learn mode, the LED will light up. Press button on receiver to put it into learn mode, LED will also light up. Once both are lit you can press the button on the remote that you want to learn, might have to press it more than once. Once it syncs the LED's will turn off, now press the button again to verify that it is working.

I don't believe you can because the 850LM utilizes the Security+2.0 technology and the 971LM is Security + 390MHz.

Sorry, I was not able to get my units to communicate with the liftmaster unit. The lights flickered but no luck with programming the unit. I have not pursued the matter with the company yet. good luck.

Hey Marilyn- Your operator can use a few remotes. The 973lm would be the 3-button remote that you'll need. The manufacturer has begun making them obsolete but you've got a couple of options. The 893max for 3 - buttons or a universal 375lm for 2 - buttons would work great. Please let me know if you have any further questions. Thanks...Matty

Funny I have a purple learning button on my Liftmaster opener but this remote has failed to respond. My existing liftmaster remotes were programmed without any issues.

Harry, I cannot give you a definitive answer, but the liftmaster website says the following: Order the 377LM if: Your garage door opener motorhead has a purple learn button, or Your garage door opener motorhead has a purple antenna, or Your original remote has silver buttons with glowing blue lights, or Your original remote has black buttons and this logo: (cannot get the logo to copy to this response so you will have to go to the Liftmaster website to see it.) Hope this helps a little

My Liftmaster calls for a 376 but it is no longer available. I took the chance that mine was also 315MHz and it worked fine. I also have the same color button. Hope this helps.

I am not familiar with your opener, but The LiftMaster 850 basically just makes a contact, the same as a doorbell type switch. If you have two wires that lead to a wall mounted switch, it's almost a certainty it will work. If you have a wiring diagram inside your current opener it may help you find a voltage source to operate the LiftMaster. If you have terminals for the doorbell switch wires on the outside of the opener, just follow the wires to the inside of your opener. This will tell you what wires need to make contact to operate your opener. Disconnect and run those two wires to the Liftmaster. Very easy.

I am not familiar with that particular garage door opener but the liftmaster works by being connected to the pushbutton connection of your opener. The remote receiver is built into the unit. It should work for you.

Yes, I have three remotes programed. Be sure to have all the correct pins in the remotes connected. Then let the lift motor "learn" each remote.
