Common Problems with Garage Door Sensors
From my experience as a technician, one of the most frequent issues is sensor misalignment. These sensors are located on either side of the door, near the ground, and they communicate via an infrared beam. If this beam is interrupted or misaligned, the door won’t close.
How Do You Know the Sensors Are Misaligned?
- The garage door starts closing but immediately reverses.
- The indicator lights on the sensors are blinking.
- There’s visible dirt or debris blocking the sensor lenses.
Real-Life Example
In Rockville, MD, I assisted a client whose garage door refused to close. Upon inspection, I noticed that one sensor had been accidentally bumped by a lawnmower. After cleaning the lens and realigning the sensors, the door operated perfectly. The cost? Just $75 for a quick adjustment.

Unique Challenges in Arlington, VA
Arlington’s weather fluctuations often cause sensor brackets to loosen. Homeowners also frequently face issues due to improper garage use, such as storing heavy items near the sensors. Regular maintenance can prevent these problems.
Preventative Maintenance Tips
- Clean the sensors regularly.
- Ensure proper alignment after any heavy object is moved near the sensors.
- Schedule an annual inspection with a professional technician.
Lesser-Known Issues and Industry Insights
