Sensor lens visibly dirty or knocked out of position
How Our Sensor Repair Process Works
We check alignment between both sensors first, since a slight bump is often all it takes to throw them off. If alignment isn't the issue, we check the wiring and the sensor units themselves for damage or wear.
Bloomington Homeowners We've Helped
Sensors sit low near the garage floor, so they're easy to bump with a bike, a lawn mower, or a stray snow shovel. A quick realignment often solves what looks like a bigger problem.
Insurance & Warranty Coverage
Sensor issues from accidental bumps or normal wear typically aren't insurance matters. Every sensor repair comes with a written parts-and-labor warranty.
Minnesota's humid summers are the other common trigger, not just winter cold. Condensation and moisture buildup around the sensor lens can interfere with the beam the same way dust or a physical obstruction would, so a sensor problem that shows up in July is just as real as one in January.

Bloomington, MN
A homeowner's door had started reversing every time it tried to close. Our technician found a sensor knocked slightly out of alignment, likely from a bumped bike, realigned it, and the door has closed properly ever since.

Bloomington homeownerFrequently Asked Questions
Why does my garage door reverse right before it closes?
That's almost always a sensor issue, either misalignment or an obstruction in the sensor's beam path.
Is it normal for one sensor light to be a different color than the other?
Yes, colors vary by brand. What matters is whether the light is steady or blinking, a steady light means proper function.
Can I realign the sensors myself?
Sometimes, a slight nudge back into alignment can work, but persistent issues usually need a technician's diagnosis.
What causes sensors to go out of alignment?
Usually an accidental bump from a bike, mower, or other object stored in the garage.
Do dirty sensor lenses cause problems?
Yes, dust or spider webs can block the beam just like a physical obstruction would.
How long does sensor repair take?
Most sensor repairs, including realignment or replacement, finish in under an hour.
Will a sensor issue affect my whole opener system?
No, sensors are a separate safety component from the motor, though the opener won't close the door if sensors detect a problem.
Is a blinking sensor light dangerous?
Not dangerous, but it means the safety system isn't confirming a clear path, worth fixing promptly so the door functions normally again.
