Door Closing Issues on LiftMaster 8500
As the title says, I am having issues with door not wanting to close, especially if it stays open longer. Sensors are aligned, I keep checking the tensioner as well, but none of that seems to work. It will only close when I unplug and plug the power cord, but that’s only a temporary solution. As a full disclaimer, I did back the car into this door about a year ago when it was half open, and bottom panel is not straight (not sure if this matters as it worked fine until recently). I replaced springs about 2 months ago. The Liftmaster is from 2016. I am guessing this is probably a logic board? How long are they supposed to last? How hard is it to replace?
