LiftMaster code 4-1 to 4-4
The door starts, then stops or reverses
Check this first, then a proThe opener felt the door bind, stick or hit something. The maker lists a broken spring and a door lock among the causes.
What to do: Clear anything in the door’s path and check it isn’t locked. If it still sticks, call a pro to check the springs and tracks. If the door itself is fine, the travel limits may need setting again, using your manual.
Don’t lift or force the door by hand: if a spring is broken, the door can fall. Springs and cables are a pro’s job. DASMA
