1. Safety sensors are blocked or out of line
The two small sensors near the floor on each side of the door must see each other. If something is in the way, or one got bumped, the door reverses. Check that both little lights are steady (not blinking), wipe the lenses, and gently line them up.
2. The sun is blinding a sensor
In South Florida, low afternoon sun shining straight into a sensor can make the door refuse to close at certain times of day. Swapping the two sensors to opposite sides, or adding a sun shield, usually fixes it.
3. Something is in the door’s path
A trash can, a rake, or a small object on the track can stop the door. Look along the bottom and both tracks.
4. The remote or wall button
Try the wall button. If it works but the remote doesn’t, replace the remote battery and check that the lock or vacation button on the wall control isn’t turned on.
5. The close limit or force setting is off
If the door touches the floor and then goes back up, the opener may think it hit something. The close limit and force settings on the opener need adjusting; follow your opener manual or call us.
6. A bent track or broken roller
If the door binds or sits crooked, stop using it. Bent tracks and broken rollers can let the door come off track.
7. A broken spring or cable
If the opener hums or strains and the door barely moves, a spring or cable may be broken. Don’t keep pressing the button — it can burn out the opener. Unplug it and call for spring repair.
When to call a pro
If the sensors are clean and lined up and the door still won’t close, or you see a broken spring, frayed cable or bent track, call us. If your home is unsecured because the door is stuck open, we offer 24/7 emergency service.
