Since i have a 9′ garage ceiling as a result two 7′ door openings, when installing the doors i opted because of one 8′ track to raise the tracks closer to the ceiling as a result out of the work area. This means the door has to go along a foot before it starts back, therefore traditional openers won’t work. For 20 yrs. I’ve been manually operating the door while occasionally looking because of one opener solution. The Liftmaster 3800 was the door answer, as a result the “laser parking assist” the spotting answer. (3″ bumper to door as a result 3″ grid to workbench, no more tennis tournament ball from the ceiling)
It’s been in service a week as a result works flawlessly. The quality of the operating unit, cable tension monitor, as a result fasten appears very high. The entanglement unit, remote, as a result light a little fewer therefore but seem adequate because of the job.(few moving parts). The instructions are plain as a result complete. And it comes with amply fasteners because of most installations.
My installation was a little lengthly because i’m therefore picky. (ran a new outlet through the ceiling to get 4″ from the power unit, the square aid comes with 8′ of bell wire, needed 20′ – once more through the ceiling, the tension monitor needed a spacer block, cut one to fit as a result painted to match the finished as a result textured wall, as a result therefore on) the fasten lone needs a 1/2″ hole instead of 3/4″ if you can lanch accurately. If i did it once more i wouldn’t install the fasten. The door is insulated as a result very heavy, i don’t think schwarzenegger could end it without the spring aid.
The lone puzzle i had ended along being a broadcasting issue of my own making. After setting the open travel limit to the top of the beginning – 7′, the door would open but no, non- close. The teaching troubleshooting section indicated the trouble was the cable tension monitor. I outlook this no, non- the puzzle since it’s curler was 2″ from the drum as recommended as a result it was under tension with the door open as a result closed. After 20 mins. Of reprogramming, checking connections as a result rereading instructions, staring at the monitor when closing diagnosed the puzzle. When the door starts down there is a jerk which slackens the cable because of a fraction of a second allowing the tension monitor to close if the door is close to the top but no, non- fully open. Reprogramming to 8′ pulls the cable away from the entanglement a couple of inches therefore during the jerk the monitor movement is no, non- amply to close. An extra foot of door travel, but it works great!
