Hi everyone,
Our garage door has not been fully opening or closing for some time now, but it is happening more frequently as of late. It is a Chamberlain Liftmaster Professional Formula 1. Some more details below.
It won't stop in the same spot everytime, and it stops both while closing and opening.
It stops regardless of if we are using the outdoor 4 digit keypad, or the indoor single button remote.
We've had two service guys look at it and the first had no suggestions. The second increased the "open force" setting. It worked correctly two or three times then the issue returned.
There is no obstruction on the track and the sensors are clean and aligned correctly.
Our solution has pretty much just been waiting 60 seconds and then trying again until it works properly.
Any ideas appreciated, please let me know if you need more detail or pictures. Thank you!
If it is stopping in different places every time, your circuit board is going bad

Yup. We recommend a new operator. Boards are a couple hundred just for the part
