Garage door problems are on the rise and mine is experiencing another one.
This morning, the door went up and stopped about 3/4 open. I lowered it with the remote, then reversed to open again helping it along by pushing it up. When leaving for work, it would come down a partial way then go back up. I didn't have time to troubleshoot until now (after work).
This morning, I removed the center connector of the door to the opener for manual operation. Upon troubleshooting just now, the opener has a travel of about a 1 to 3 feet. I push the remote and it moves down, stops, then moves up on it's own. I disconnected the limit switches and tried again. The same thing happens. I increased up and down force but nothing. I know it's not the door causing the problem for many reasons but obviously, the main reason is it's disconnected. Therefore, it's in the opener itself but I have no idea where to even look. All gears, chain links, tracking, teeth, etc. are lubricated, intact, secure, etc. I'm dumbfounded. Any suggestions?
Thanks
