A great improvement over chain and screw drives--easy adjustment Jan 05, 2009
My 20 year-old garage has now experienced three openers--chain drive, screw drive, and the subject jack shaft drive. My original chain drive unit died, and I replaced it with the screw drive unit. In both cases, with a double-wide garage door, I found the center pull of the drive (on the top center of the door was causing, over the years, some serious (2-inch Plus) distortion of the door. This may have been due to incorrect settings of the force controls for the door.
I found the basic installation of the 3800 to be straightforward. I took much longer to install because of adding an electrical outlet and hiding the control wiring nicely in a finished garage. I found that a 3/4" drill bit was not necessary--the largest (1/2") bit with a very small amount of hand filing was all that was needed for the deadbolt locking mechanism.
By far the nicest part of the installation was the limits adjustment. Having suffered through placement of micro-switches on the rail of my previous screw drive opener, the all-electronic/push button magic of the 3800 was a snap.
The second nicest part is the control unit, with its alphanumeric display and remote programming are so much nicer than climbing on a ladder, pushing a button, watching blinking lights, etc., associated with other openers.
Last, the unit is not yanking on the middle of my garage door, both avoiding the distortion of my now-structurally weakened door, and avoiding the noise from the screw or chain drive being amplified like a drum head by the garage door. This unit is quiet!

Liftmaster 3800 Jackshaft opener Sep 29, 2008
I purchased this opener and installed it in about 2.5hrs. I had a slight advantage because I was able to utilize the safety sensors from my previous opener, thus saving a small amount of time with the new wiring.
Unlike some other reviewers, I found the installation instructions very clear and easy to follow. In fact; most sections could be read once and the component installed without referring back to the manual. As another reviewer stated; it is a good idea to make sure you have all of the necessary tools on the included tools required list before starting, to avoid un-necessary interruptions once you get going.
The only odd thing I noticed was during the initial door travel setup. When setting the upper and lower stop limits per the directions, it was necessary to perform the steps at least twice before the unit remembered the travel limits. Just as an experiment, I reset the unit three times, and all three times it required at least two attempts before the programming would take. It's not a problem but just something to be aware of.
The unit has been installed and working flawlessly for two months now and I have to say that this is the smoothest, quietest opener I have ever seen. During my initial testing of the unit, I noticed squeaks and creeks coming from my door hinges and rollers that I was unable to hear over my old chain drive unit. After a quick tune up and lube, everything got quite and now the whole door opening cycle is not much louder than my freezer running.
One other operating point, with this opener you can set the full open limit much higher than a conventional unit. The framed opening of my main door is 8'6" high but with a standard opener, the last door panel never fully retracts into the garage leading to an opening that was only 6'11". This unit pulls the door completely up. As the owner of lifted oversized vehicles, this was one of the key selling points.
The cost is a bit higher than other conventional openers but is well worth it. I am planning on replacing the openers on my other two doors with these units. Which can all be operated individually by the one remote provided with the original unit.

Best opener ever! Feb 28, 2008
I have owned and installed many garage door openers.The Liftmaster 3800 is by far the easiest to install. It is also the quietest.If there is any draw back it would be considered a little pricey. I paid $365 thru Amazon. The best price I could find locally was $495 out the door & $695 installed. It took me about 3 hours to install and as with all projects that time could be cut in half on the second one. I would recommend this product to anyone who has the space to install it.

Great Product Feb 25, 2008
I had modified a Wayne Dalton iDrive (modifying it to work very much like the LM 3800) to operate my high lift door but after three years it started to show wear. The LM 3800 was the obvious choice since it is made for this type of application.
The downside is the installation, it can be a lot more involved than the directions imply, especially finding a mounting spot for the cable tension switch. In the end it all worked out and the opener works very well!
One shortcoming, the WD opener used a wireless wall console but the 3800 does not have such a feature. Because of this I had to run the wires from the middle of the ceiling (where the original opener was mounted and where the house was wired) to the side of the door for the 3800. I also had to wire the safety lights too since the original wires also went to the middle of the ceiling.

Best Opener Ever!! Feb 11, 2008
This opener is awsome! The soft start and stops make a real difference. The control panel offers plenty of system preferences and the time/temp read-outs compliment any space. Remote operating distances are not that great being that I have a steel building, but I expected this. Also, one of those "Unibits" works well for the lock hole.
Nice product!
