SENSORTROUBLE.FIXED TODAY.
The two little eyes near the floor are the safety sensors. When they fall out of alignment, get dirty, or fail, the door refuses to close and the opener light flashes. Most of the time it is a quick alignment, sometimes a sensor swap, and we carry both on the truck.
Same-day. No upsell. Family-owned.
- Often a same-visit fix, sometimes free if it is just alignment
- We test the wiring, not just the sensor (the usual real cause)
- Matched replacement sensors stocked for every major opener
- Auto-reverse safety verified before we leave
- Stockton-based, family-owned, neighbor-trusted

Why Safety Sensors Act Up
Federal law has required these photo-eye sensors on openers since 1993, so every modern door has them. They are also the single most common reason a door won't close, and usually the cheapest to fix.
- Sensors bumped out of alignment by a car, bike, or bin
- Sun glare washing out the beam at certain times of day
- Dust and spider webs on the lens
- A pinched, chewed, or sun-brittle sensor wire
- Corroded contacts from winter fog or a sprinkler splash
- A genuinely dead sensor at end of life
