AfterSensor Calibration in Los Angeles, CA
Sensor calibration for garage doors in Los Angeles typically costs between $95 and $150, depending on whether the issue is a simple alignment adjustment or requires wiring repairs. When your garage door refuses to close or reverses immediately upon hitting the button, the safety eyes are almost always the culprit. At Servo Garage Doors Los Angeles, we provide a flat, written price for this service before our technician touches a single screw, as required by Clause 1 of The Haven Standard.
If you are looking for Garage Door Repair in Los Angeles, you have likely noticed that the garage door system is sensitive. The safety sensors, often called photo eyes, are the two small boxes mounted near the floor on either side of your door. They send an invisible infrared beam across the opening. If that beam is broken, blocked, or misaligned, the opener logic board refuses to close the door for safety reasons. In the Los Angeles area, we see this frequently due to the specific soil conditions that cause foundations to settle, shifting the door frame just enough to throw the sensors out of their precise alignment.
Marcus Deller and the team at Servo Garage Doors Los Angeles operate as an independently owned and operated business. We do not believe in guessing or vague estimates. When we arrive at your property, we perform a diagnostic check, photograph the state of your sensors, and provide our Garage Door Repair services written scope of work. You will know exactly what is wrong and exactly what it will cost before we proceed. If you need assistance today, call us at (213) 348-6550.
When You Need Sensor Calibration
Garage door sensors are designed to be sensitive, which is good for safety but can be frustrating when they lose calibration. You do not always need a full replacement when your door acts up. Often, the sensors just need to be brought back into alignment. Here are the common symptoms that indicate you need a professional calibration:
- The door reverses immediately: When you press the wall button or remote to close the door, it starts to go down but pops back up immediately, and the opener lights flash. This is the classic sign that the infrared beam is being blocked or the sensors are misaligned.
- The door closes only if you hold the button: If you have to press and hold the wall-mounted button to force the door shut, the system has defaulted to an override mode because it detects a sensor error. This is a safety bypass and should be addressed promptly.
- The LED on the sensor is flickering: Most modern openers from brands like LiftMaster, Genie, and Chamberlain have an LED light on the sensor. If that light is blinking or dim rather than a steady glow, the connection is poor or the alignment is off.
- Physical damage to the bracket: In busy households, it is easy to bump the sensors with a bicycle, a trash can, or a car bumper. Even a slight nudge can break the line-of-sight between the two eyes.
- Foundation shifting: Los Angeles homes, especially those in hilly areas or with older concrete slabs, can experience minor foundation movement. Over time, this movement can pull the door tracks and the attached sensor brackets out of square.
- Wiring degradation: The low-voltage wire running from the opener to the sensors can become brittle, especially in the heat we experience in Southern California, leading to intermittent signal loss.
Our Sensor Calibration Process
At Servo Garage Doors Los Angeles, we follow a strict, documented process for every service call. We treat every job as if it is the only one we are performing today, ensuring the work is done right the first time. Our process adheres to The Haven Standard, which prioritizes transparency and evidence.
- Visual Inspection: We start by inspecting the physical condition of the sensor eyes and the wiring leading back to the motor unit. We look for corrosion, loose connections, or pinched wires.
- Documentation: Per Clause 4 of The Haven Standard, we photograph the current state of your sensors and the surrounding area. You will receive this photo record, giving you clear evidence of what we found when we arrived.
- Cleaning and Alignment: We clean the lenses to ensure a clear path for the infrared beam. We then use a precision level to ensure the brackets are mounted correctly and the eyes are facing each other directly.
- Signal Verification: We test the signal strength between the sending and receiving eye to ensure it is robust enough to handle the vibration of the door opening and closing.
- System Testing: We cycle the door multiple times to ensure it operates smoothly. We also verify that the safety reversal feature functions correctly by placing an object in the path of the door to trigger the safety stop.
- Final Sign-off: We provide you with the written record of the work performed, ensuring you have a paper trail for the service.
Safety Warning: While sensor calibration is a low-voltage procedure, the garage door system itself operates under high tension. The torsion springs, Spring Repair cables, and bottom brackets are under significant pressure that can cause severe injury if mishandled. If you are unsure about the mechanical state of your door, do not attempt to adjust components near the cables or springs. Call a trained professional at (213) 348-6550 to handle the adjustment safely.

FAQs - Sensor Calibration
How do I know if my garage door sensors are bad or just dirty?
If your sensors are just dirty, wiping the lenses with a soft, dry cloth will often clear the issue immediately. If the door still refuses to close or the LED on the sensor remains dark or flickering after cleaning, the issue is likely an internal component failure or a wiring break, which requires professional diagnostic equipment to identify.
Can I fix the sensor alignment myself?
You can often adjust the alignment by gently loosening the wing nut on the sensor bracket and moving it until the LED light turns solid. However, if the bracket is bent, the wiring is damaged, or the logic board on the motor is the actual cause of the failure, you will need a professional. If you are not comfortable working near the door Track Realignment or if you see any fraying on the cables, call us at (213) 348-6550 to avoid any risk of injury.
Why does my door only close when I hold the wall button?
This is a safety override mode. Your garage door opener has detected a fault with the safety eyes-either they are blocked, misaligned, or the wire is broken-and it will not close automatically because it cannot guarantee the path is clear. Holding the button bypasses the safety sensor check, which is why it works, but you should not rely on this method as it removes the safety protection for your family and pets.
Do you service all garage door opener brands?
Yes, we service all major brands, including LiftMaster, Genie, Chamberlain, Raynor, and others. Because we are an independently owned and operated business, we are not tied to any single manufacturer, which allows us to carry the correct parts for almost any system installed in Los Angeles homes.
