Call 650-912-1817 to describe the problem and confirm current availability.
Symptoms worth describing on the call
Let us know whether the wall button works, whether the remote works, what the safety-sensor lights are doing, and whether the door can move normally by hand when safely disconnected.
Sensors and travel behavior
A door that starts closing and then reverses can be related to an obstructed or misaligned safety sensor, a travel-setting issue, or mechanical resistance in the door.
Mechanical issues can mimic opener failure
If a spring is broken or the door is binding in the tracks, the opener may struggle even if the opener itself is not the primary fault. The whole door system should be considered.
