Garage Door Sensors in Denver, CO

If your door reverses unexpectedly, won't close, or has blinking opener lights, misaligned or faulty sensors are usually to blame.

How Our Garage Door Sensors Service Works
Simple, transparent, and built around getting you back to normal fast.
Sensor Diagnosis
We test the sensors with and without the door in motion to isolate the problem — alignment, wiring, or sensor failure.
Alignment Correction
Most sensor issues are alignment problems. We realign the send/receive units until the indicator lights show a solid green/amber.
Replacement if Needed
If a sensor has failed, we replace it with a compatible unit for your opener brand.
Full Cycle Test
We test the door with an obstruction present to verify the reversal feature works correctly.
Frequently Asked Questions
Why does my garage door go back up when I try to close it?
The most common reason is a misaligned safety sensor. The sensors detect an obstruction (even when there isn't one) and reverse the door as a safety measure. We can realign them in minutes.
How do I know if my sensors are misaligned?
Look at the indicator lights on each sensor unit. If one is blinking or orange instead of solid green/amber, it's misaligned or obstructed.
Can I just unplug the sensors?
No. Sensors are a required safety feature. Most openers won't operate correctly without them, and bypassing them creates a serious risk of injury.
