Does this look like it needs a new gear?
Chamberlain Liftmaster Formula I Whisper Drive model 1280R
About a week ago the garage door stopped half way down and wouldn’t move back up. I released the door and replaced some of the rollers in the track. That didn’t fix it so I took the belt off and inspected the teeth. Nothing missing there. The coil spring doesn’t have any gaps that I can see(not gonna touch that at all). The coil spring was replaced in 2022. After hooking the belt back up to test the trolley, the trolley moves 3 feet at the most and then on the reverse I hear a loud clacking noise. Now it just hums one way and loud clacking the other way.
I don’t exactly have the money to replace the opener. I need to have the door rebalanced since it doesn’t hold itself up without sliding down. Does anyone have any ideas? I think I can replace the gear in the picture. I can also take a look at the board but I don’t see the classic puff of smoke or anything that would signify the start capacitor being blown.
Also I don’t know how to set the open and close limit on this opener or reset them.
The led light flashes 5 times on the opener.
