AfterSensor Calibration in Stafford, TX
Garage door sensor calibration in Stafford, TX, typically costs between $95 and $175, depending on whether the issue is a simple alignment adjustment or requires wiring repairs. If your garage door reverses unexpectedly or refuses to close unless you hold the wall button, the safety eyes are likely misaligned or faulty. At Servo Garage Doors Stafford, we resolve these issues by testing the signal strength, cleaning the lenses, and ensuring the mounting brackets are secure. Our goal is to verify your door operates safely according to the manufacturer’s specifications. If you are experiencing these issues, call us at (346) 421-5125 for a transparent, written estimate before any work begins.
We operate as an independently owned business under The Haven Standard. This means we don’t just “fix” doors; we document the entire process. When we arrive at your home in Stafford, we photograph the failed sensor or the misaligned bracket before we touch a single tool. This is Clause 4 of The Haven Standard, ensuring you see exactly what we found. Whether you have a newer belt-drive system or an older chain-drive opener from brands like LiftMaster, Chamberlain, or Craftsman, we provide a written scope and flat price upfront. This is a standard part of our Garage Door Repair in Stafford service, which you can read more about on our home page.
When You Need Sensor Calibration
Safety sensors, often called photo eyes, are the two small boxes mounted near the bottom of your garage door tracks that may need Track Realignment. They project an invisible infrared beam across the opening. If that beam is broken, the door stops or reverses. In Stafford, we often see these sensors knocked out of place by lawn equipment, bicycles, or the natural settling of a home foundation. You likely need professional calibration if you notice these specific behaviors:
- The door reverses immediately: If the door starts to close but reverses back to the open position, the sensors are likely failing to “see” each other due to misalignment.
- The wall button works, but the remote doesn’t: While this can indicate a logic board issue, it frequently points to a sensor signal that is too weak to trigger the safety circuit reliably.
- Blinking LED lights: Most sensors have indicator lights. If the light on either sensor is flickering, amber instead of green, or completely dark, the connection is compromised.
- Physical damage to brackets: If the metal bracket holding the sensor is bent or loose, the sensor cannot maintain a consistent beam, even if the electronics are functional.
- Obstruction errors: If the door stops mid-travel without any physical object in its path, the sensors are likely detecting “ghost” obstructions caused by vibration or dirty lenses.
Safety is not a suggestion; it is a requirement. If your sensors are not functioning, your garage door effectively loses its primary safety feature and may require our Garage Door Repair services. If you notice any of these signs, avoid trying to force the door closed by holding the wall button for extended periods, as this can strain the motor and cable systems. Call us at (346) 421-5125 to have a technician inspect the alignment.
Our Sensor Calibration Process
We follow a strict, evidence-based procedure for every service call. We do not guess at the problem. Our process is designed to provide you with a clear, documented record of what is happening with your door system.
- Visual Inspection and Documentation: Upon arrival, we inspect the physical mounting of the sensors. Per Clause 4 of The Haven Standard, we photograph the current state of the sensors and brackets to show you exactly what we are dealing with before we start.
- Signal Testing: We use an ohmmeter to test the continuity of the wiring running from the motor unit to the sensors. Many calibration issues in Stafford homes are actually caused by wire breaks hidden inside the wall or along the ceiling tracks.
- Alignment Adjustment: If the sensors are simply misaligned, we adjust the mounting brackets to ensure the infrared beams align perfectly. We do not use “quick fixes” like duct tape or zip ties; we use proper mounting hardware.
- Cleaning and Lens Check: We clean the lenses of any dust, spiderwebs, or debris that may be obscuring the signal. This is a common issue in garages that are not climate-controlled.
- Final Safety Test: We perform a standard obstruction test. We place a test object in the path of the door to ensure the sensors trigger the reversal mechanism instantly. We then provide you with the final documented photo record of the completed work.
Every job we perform at Servo Garage Doors Stafford includes this documentation. You will know exactly what the technician found, what they did, and what the final cost is, with no surprises or hidden fees.

FAQs - Sensor Calibration
How do I know if my garage door sensors are bad?
The most common sign is that your garage door will open normally but refuses to close unless you hold down the wall-mounted button continuously. This manual override is a safety feature that engages when the opener detects the sensors are not communicating, preventing the door from closing automatically to avoid potential injury or damage.
Can I fix misaligned sensors myself?
While you can visually inspect the sensors for obstructions or loose brackets, we recommend caution because garage door systems involve high-tension cables and springs that can be dangerous if handled incorrectly. If you are comfortable, you can gently nudge the brackets to see if the LED lights turn solid, but if the wiring is damaged or the logic board is the culprit, a professional inspection is the safest route. If you are unsure, call (346) 421-5125.
Are sensors universal between different brands?
No, safety sensors are not universally interchangeable between manufacturers like LiftMaster, Genie, and others. Each brand uses specific signal frequencies and wiring configurations. Using the wrong sensor kit will prevent the system from operating and may damage your garage door opener’s logic board. We carry specialized parts to match your specific system.
Do you provide same-day service for sensor repairs?
Yes, we prioritize safety-related repairs like sensor malfunctions. Because a garage door that will not close is a security risk for your home, we make every effort to get a technician to your property as quickly as possible. When you call (346) 421-5125, we will provide you with a clear window of when you can expect us.
