COMMENT: guy told me this is what I needed by Timothy T 5/21/2015
COMMENT: I have a 3800 door opener and it works very well by Bill O 4/28/2015
QUESTION: Does the 3950 allow Up / Down / Stop, so that you can open/close the door and stop it at any point? E.G., to leave the door open 6" at the bottom for air flow, or for the cats to come/go, but not the neighborhood teenagers. by Daniel P 3/9/2015
ANSWER: You can open or close the door as little or as much as you want. I also ordered two remote controls with my opener, and they work just fine also to do what you want to do with the opener. by Nora W a
ANSWER: Yes. You can open close and stop at any point of operation. You can also use remotes and the keypad the same way. by dan w a
ANSWER: Yes the 3950 has all three functions up, down & stop .<br />This operator is a great unit that very quiet operation .<br />Very dependable unit.<br />I have 3 of these and love them. by Byron L a
ANSWER: Yes, you can do that. It works just like a standard garage door opener. One push to open. Another push stops it on the way up. On the way down, a push of the button reverses the door and sends it back up; but another push stops it again. We have two of these and they are great. We also have several two-button remotes and can operate either door independently from the cars or the golf cart just like standard garage doors. by Michael C a
QUESTION: Will the factory installed remote control in my vehicle work with this opener? by Dan B 9/14/2014
ANSWER: I did not program my openers to my vehicle. I would think they would be compatible but not sure. In the past I have programmed vehicles 2010 Tahoe and 2008 king ranch to gate openers that were purchased from tractor supply. From what I understand these are a newer version of the old chamberlain openers anyway. by Tommy R a
ANSWER: Yes it will. Operator has logic programming same as other operators by kevin m a
QUESTION: want to install on a Janus 650 roll up to mount sproct to drum ? by dean h 8/27/2014
ANSWER: There are generally two kinds of jack shaft for these roll up doors. A live jack shaft that rotates with the drum and a dead jack shaft which remains stationary as the drum rotates on it as an axle. The Liftmaster comes with parts that can adapt it to work with either type of shaft. With the live shaft, the sprocket mounts directly to the shaft and the chain from the liftmaster directly rotates the shaft and therefore the drum that rolls the door up and down. On the dead shaft, there are a number of spacers short to long tubes and three bolts and nuts that permit a different sprocket also supplied to slide over the dead shaft and be bolted directly to the end of the rotating drum by selecting the appropriate spacers or combination of spacers. As you only need one type of sprocket depending on your installation, you end up with an extra sprocket with each installation. by Michael C a
ANSWER: The sprocket comes with three long bolts and three spacers to go over the bolts. My door drum had the holes for the bolts pre drilled, but if not, just drill your own. by Robert O a
ANSWER: The opener comes with two sprockets, spacers and bolts. My door already had holes so it was easy by gary b a
ANSWER: I hired a local independent installer who installed and wired it for around $300. This cost with combined with the cost of the unit and the remote openers brought the total cost to around $700. <br />This crushed the cost of a full commercial install that was ranging from $2000 to $3500.<br />Have been using this unit for 1 year so far with no issues. I believe the professional install was worth it everything straight, wired nicely, and I did not have to climb a ladder. by Andrew T a
ANSWER: My door previously had a chain to roll the door up. I had the Liftmaster installed. Since I hired the installation out to Garage door repair people I cannot answer your question of how to mount to the drum. <br />However, mine works perfect the way they did it. <br />Good luck with your project. I paid $150.00 for the installation. by Nora W a
