QUICK ANSWER
Door reverses or the opener light blinks? Check the sensors. They sit near the floor on each side of the door. If one is dirty, bumped, or blocked, the door refuses to close.
The two small eyes near the floor protect people and pets by stopping the door if something is in the way. They only work if they see each other.
Why sensors stop the door
Out of alignment
A bump from a bike or a mower tilts one eye just enough to lose the signal.
Dirt, frost, or sun glare
A smudged lens or a frosty morning can block the beam. Direct sun can also confuse older sensors.
A damaged wire
The thin wires that run to each sensor can get nicked or pulled loose over time.

HOW NEXTDOOR FIXES IT
We clean and realign the sensors, test the wiring, and replace any unit that is worn out. Then we check that the door reverses properly when something crosses the beam. If the trouble runs deeper, we look at the opener’s logic board.

Wipe both lenses with a soft cloth and make sure the little lights on each sensor are steady. If one is blinking, it needs to be nudged back into line. Never disable the sensors to get the door to close. They are a federal safety requirement, and we will not bypass them.

Questions about safety sensor repair
Why does my door reverse right before it closes?
The safety sensors near the floor may be dirty, bumped, or out of line. Wipe the lenses and check that both lights are steady. If it keeps happening, we realign or replace them.
Can you disconnect the sensors so the door closes?
No. The sensors are a safety feature that protects people and pets, and federal rules require them. We repair them instead of bypassing them.
