Door goes down, then right back up?
The two small sensors at the bottom of the tracks stop the door from closing on a child, a pet or a car. When they're dirty, knocked out of line or wired wrong, the door refuses to close. Often it's a two-minute fix.
Most sensor repairs, time on site20 – 45 min

Sound familiar?
- Door reverses right before touching the floor
- Opener light blinks when you try to close
- Closes only if you hold the wall button
- One sensor light blinking or off
- Sensors bumped by a bike or a trash can
- Door doesn't reverse on an object (dangerous)
What we do
We check both sensor lights, alignment, lens condition and the low-voltage wire back to the opener. Sun glare in the late afternoon can also blind a sensor; we can reposition it or add a shield.
Every sensor visit ends with the auto-reverse test: a 2×4 flat under the door. It must reverse on contact. If it doesn't, the opener's force setting gets adjusted before we leave.

Two minutes, no tools
Wipe both lenses with a soft cloth. Look at the lights: both should be solid. If one blinks, gently bend its bracket until the light goes solid. Check for a trash can, a hose or a spiderweb in the beam. That fixes most 'broken' sensors.
Questions about safety sensor repair
No. They're required by federal safety standards and they protect kids and pets. We fix them, we don't bypass them.
Low sun hitting the receiving sensor. Swapping sides or adding a shade usually solves it.
Once a month, put a 2×4 flat under the door and close it. It should reverse on contact.
