Garage door will not close without holding down the wall button. Only the wall button will close it. Neither wireless remotes work. I have disconnected the safety devises and still have the same issue.
I have had this happen twice, and it was due to the safety sensors being disconnected. Once I reconnected them and adjusted them to face each other, it fixed it.
I just paid $50 to find out that Liftmaster garage door openers have issues if you place LED bulbs in the opener.
After the tech swapped the bulbs for incandescent, it is working fine.
Also, 1 sensor is green and 1 is amber, and that is normal. Only adjust the green sensor, if you have issues closing without override- per service tech.
