AfterSensor Calibration in Van Nuys, CA
Garage door sensor calibration in Van Nuys typically costs between $85 and $145, depending on whether the issue stems from a simple bracket misalignment or requires a repair to the wiring harness. This service ensures your safety eyes are accurately aligned so the door reverses properly when an obstruction is detected. If you are experiencing issues with your door, please call us at (213) 418-2520 to schedule our Garage Door Repair services. We provide upfront pricing before any work begins, following the requirements of The Haven Standard.
Safety sensors, often called photo eyes, are the small devices located near the floor on both sides of your garage door opening. They emit an invisible infrared beam. When that beam is broken by an object, the door stops or reverses to prevent injury or damage. Because these components are exposed to the elements and vibrations from the door’s operation, they often drift out of alignment. At Servo Garage Doors Van Nuys, we perform precise calibration to ensure these systems function exactly as the manufacturer intended.

When You Need Sensor Calibration
You do not always need to replace your sensors when the door fails to close. Often, the system just needs a professional adjustment. We look for these specific symptoms when we arrive at your home in Van Nuys:
- The door reverses immediately upon closing: This is the most common sign. The system thinks there is an obstruction even when the path is clear.
- Blinking LED lights on the motor unit: Most modern openers, such as those from LiftMaster or Chamberlain, will flash a specific error code on the motor housing when the sensors are misaligned or obstructed.
- The door only closes if you hold the wall button: This is a manual override mode. If the sensors fail, the system forces you to hold the button to ensure you are physically watching the door, which is a significant safety feature but indicates a sensor fault.
- Physical damage to the sensor bracket: In older Van Nuys homes, the wood or drywall where the sensor is mounted can settle or warp, causing the bracket to shift. Even a slight angle change prevents the infrared beam from connecting.
- Intermittent failure during the day: If your door only fails to close when the sun is hitting the sensors directly, the sunlight might be flooding the receiver with infrared light, causing a false signal. We address this by adjusting the angle or installing a shield.
Our Sensor Calibration Process
We approach every service call with the same documented process. We do not guess, and we do not perform work that is not required. Our goal is to fix the issue and provide you with a record of what we found, adhering to the founding rules of our business. As part of our commitment to transparency, we follow these steps during every sensor calibration:
- Visual Inspection of the Beam: We check the alignment of the photo eyes and ensure the lenses are clean. Dust and cobwebs are common culprits in this area.
- Mounting Bracket Evaluation: We inspect the brackets for stability. If the bracket is loose or bent, the sensor will never stay in alignment. We secure or repair the mount to ensure it stays in place.
- Wiring Continuity Test: We check the low-voltage wire running from the motor to the sensor. In older installations, wire insulation can become brittle or damaged by pests, causing intermittent signal loss.
- System Alignment: Using a laser alignment tool, we calibrate the sensors to ensure the beam is perfectly centered on the receiver.
- Documented Photo Record: Following Clause 4 of The Haven Standard, we photograph the failed component or the misaligned state before we start any work, and we photograph the corrected state once the job is complete. You receive this record so you have evidence of exactly what was done.
Safety Note: While sensor calibration is a standard adjustment, the garage door system itself involves high-tension components like springs and cables. If you notice the door is heavy, the cables are frayed, or the torsion spring shows signs of wear, do not attempt to adjust these parts yourself. These components are under extreme tension and can cause severe injury. Always call a trained professional for any work involving the mechanical lifting system.

FAQs - Sensor Calibration
Can I fix misaligned sensors myself?
You can often fix a simple misalignment by gently adjusting the sensor bracket until the LED light on the unit turns solid, but if the wiring is damaged or the bracket is compromised, you will need professional tools to ensure the fix lasts. If you attempt this, ensure the garage door is fully closed and the power is disconnected to avoid any accidental movement.
Why does my garage door keep blinking?
A blinking light on your motor unit is usually a diagnostic code indicating that the safety sensors are not communicating, which stops the door from closing for safety reasons. This is common in Van Nuys when older houses have settling foundations that shift the sensor brackets or when Track Realignment is needed due to years of use.
Do I need to replace my sensors if they are misaligned?
No, you rarely need to replace the entire sensor unit just because of alignment issues. We only recommend replacement if the internal electronics have failed, the lens is cracked, or the housing is broken beyond repair. We will always show you the evidence of the failure before we suggest a replacement.
