Questions & Answers

Q:Will I have to purchase the rail kit in order for this to work? I already have a garage door set up. Just need the new motor and sensors and remote. Didn’t know if I had to replace the whole shabang or just the motor

Answer This Question

A:  Hello. As long as the door does not weigh more than 650lbs and is properly balanced, yes, the opener will work on your door. If the door is taller than a 7ft standard garage door, you may need to purchase an extension kit.

      Answer This Question

      A:  Hello Cheryl. The opener would be designed for a 7ft standard garage door. You would need to purchase a 10ft rail extension kit model 7710CB-P for a 10ft garage door. Should you have any comments, concerns or questions feel free to contact customer support through https://support.chamberlaingroup.com/s/contact-us

        Don't buy Chamberlain
        Don't buy it. It doesn't come with a cable/chain. You need to buy the cable, links, attach it, you also can't attach it to the roof without more stuff. Stay away from Chamberlain.

          Reliable garage door opener
          I had an older version on this opener that came with the house. The sprocket broke, so we replaced it with a new opener. Love it!!!

            Fast install. Easy replacement for a tired old opener
            Installation was very simple and opener is working as expected. My garage was this summers project. Replace my 32 year old doors, repaint, coat the floors, and replace my old 1/4 HP Stanley opener on one door. My doors are 8 feet tall but when I originally installed my old openers there wasn't any extenders to upgrade a 7 foot opener to an 8 ft opener. I fabricated a steel bracket that attached above the door to bring opener a foot rearward. I used the same homemade bracket for this installation also. My door opens a couple of inches lass than the framed opening. I did not have the safety lights on old system but I ran those up into the unfinished garage attic and down to the openers. Also I added the Clicker keypad opener to the outside of the door. Programming that to the opener was easier than i expected. Overall I am pleased with everything on this purchase. However there is a concern that i addressed to customer support at Chamberlain that they could not answer. There was a bag in the parts box that I questioned. I even sent pictures along in my email. They could not identify these parts at all and only reference me to page 32 in the manual. Maybe it was just an error in the packaging. Hope it is not an important part that they overlooked.

            Installed 11-11 - worked fine until 11-28. Really cold morning and would not close all way down. Door was a little stuck because of cold. Tightened chain and readjusted so will see how it does on next cold morning.
              Two hours and all done.
                Garage door opener will not work with myQ app for iPhone as directions state. After several phone calls was informed the app does not work with this opener. Very misleading advertisement also will not work with my alarm system. Very unhappy with product and Home Depot.
                  Easy to install worked as expected. Only bad thing is only our motor went bad, would be nice to be able to buy just that part without the tracking.
