Review on Genie Battery Backup Model 6072H-B Wall Mounted Garage Door Opener, Black by Robert Chandrasekar

Homeowner here. I just installed three of these in a shop. I like them, but have two comments. First, alignment with the shaft. The motors tend to move slightly when operating, which I assume is due to either the alignment on the shaft or that the shaft is slightly bent - causing the motor to move as it rotates. I spoke to a Liftmaster dealer and he said theirs do the same thing, so I assume most likely the garage door shaft. I left the lag bolts slightly loose and let it move, rather than screwing it down hard. Screwing it down hard would make me think the pressure that moves the unit would be isolated within the unit, and possibly cause premature failure. Second, on the last install, on the first time I tried to close the door, the cables came off the drum. I’ve come to the conclusion this door’s spring was wound too tight, so there was no gravity pulling the door down at the upper limit. So when the unit tried to unwind, there wires came off. We’ve reset the tension, and it’s working fine now. Time will tell. I said that so that others need to check to see that the door will want to close at the upper limit. Mine was first adjusted for a manual lift, which was great, but it also kept the door at the top (took a significant pull on the rope to get it started down). Try this out before installing the unit. You need gravity to help you with this unit, not like standard garage doors. Standard doors work in a push-pull process, where this design requires gravity at the upper end to ensure the door wants to go down and the cables stay tight:on. Instructions could be improved upon. Thanks
