Since i have a 9′ garage ceiling as a result two 7′ door openings, when installing the doors i opted since one 8′ track to provoke the tracks closer to the ceiling as a result out of the work area. This means the door has to go increase a foot before it starts back, very traditional openers won’t work. For 20 yrs. I’ve been manually operating the door while occasionally looking since 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″ grate 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 wrestling hold appears very high. The wall unit, remote, as a result light a little fewer very but seem adequate since the job.(few moving parts). The instructions are clear as a result complete. And it comes with abundance fasteners since most installations.
My installation was a little lengthly because i’m very picky. (ran a new outlet through the ceiling to get 4″ from the power unit, the parking lot aid comes with 8′ of bell wire, needed 20′ – on the other hand 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 very on) the wrestling hold sole needs a 1/2″ hole instead of 3/4″ if you can practice accurately. If i did it on the other hand i wouldn’t install the wrestling hold. The door is insulated as a result very heavy, i don’t think schwarzenegger could steal it without the spring aid.
The sole dilemma i had ended increase being a programming issue of my own making. After setting the open travel limit to the top of the opportunity – 7′, the door would open but not close. The guidance troubleshooting section indicated the trouble was the cable tension monitor. I outlook this one not the dilemma 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 dilemma. When the door starts down there is a jerk which slackens the cable since a fraction of a second allowing the tension monitor to close if the door is close to the top but not fully open. Reprogramming to 8′ pulls the cable away from the wall a couple of inches very during the jerk the monitor movement is not abundance to close. An extra foot of door travel, but it works great!
