AfterSensor Calibration in New Braunfels, TX
Garage door sensor calibration in New Braunfels typically costs between $95 and $150, and in most cases, we can complete the repair during a single visit. If your garage door reverses unexpectedly or the lights on the motor unit are blinking, the safety sensors are likely misaligned, obstructed, or experiencing a wiring fault. At Mainspring Garage Door Co., we specialize in identifying exactly why your system is failing to close and correcting it so you can rely on your door again.
Since our founding in 1984, we have helped homeowners across Comal County keep their doors running. Whether you live in a historic home near downtown or a newer build in the outskirts, the principles of garage door safety remain the same. Sensors are the primary safety mechanism for your door, and when they fail, it is not just an annoyance. It is a signal that your home’s security and safety system needs attention. If you are experiencing issues, please call us at (830) 689-6216 to speak with a live person who can help you determine if you need a quick adjustment or our Garage Door Repair services.
You can find more information about our broader services on our home page, or you can explore our detailed Garage Door Repair in New Braunfels page to see how we handle mechanical issues beyond simple sensor alignment.
When You Need Sensor Calibration
Many homeowners in New Braunfels notice sensor issues during specific times of the year, particularly when the intense Texas heat causes metal brackets to expand or contract, or when heavy rains lead to moisture-related electrical faults. We recommend looking for these specific signs that indicate a calibration or repair is necessary:
- The door reverses immediately: You press the button to close the door, it starts to descend, and then it immediately reverses back to the open position without touching the floor. This often means the infrared beam is broken.
- Blinking lights on the motor unit: If you look at your LiftMaster or Chamberlain motor unit and see a light flashing in a repeating pattern, the system is telling you it has detected a fault in the safety circuit.
- One sensor light is off: The sensors should have steady lights, usually green or amber. If one side is dark, it has lost power or the internal bulb has failed.
- Physical damage to the housing: If a lawnmower, car bumper, or stray object has bumped the sensor, the bracket may be bent, meaning the beam is no longer shooting straight across the threshold.
- Sunlight interference: In New Braunfels, homes with driveways facing directly into the rising or setting sun may experience “blinding” of the sensor, where intense direct light tricks the receiver into thinking an object is in the way.
If you see these symptoms, do not force the door to close by holding the wall button. That bypasses the safety mechanism and can cause damage to the door or injury to people and pets. Call (830) 689-6216 for a professional assessment.
Our Sensor Calibration Process
When you call Mainspring Garage Door Co., you get a journeyman technician who arrives in a fully stocked truck. We do not believe in second trips for parts. We follow a strict process to ensure your door is safe and functional, adhering to our K.E.Y.S. values: Krafted right, Every time, Your home first, Standing behind it.
- Visual Inspection: We start by checking the mounting brackets. Over time, the vibration of the door opening and closing can loosen the screws, causing the sensors to sag. We tighten and level these brackets first.
- Lens Cleaning: Dust, spiderwebs, and mud accumulation are common in this region. We clean the lens of both the sending and receiving units to ensure a clear, uninterrupted infrared signal.
- Alignment Adjustment: Using a specialized tool, we adjust the angle of the sensor to ensure the beam is perfectly centered on the receiver. We test this from multiple heights to ensure a consistent connection.
- Wiring Integrity Check: We inspect the low-voltage wire running from the motor unit to the sensors. We look for staples that have pierced the casing, frayed wires, or corrosion at the terminal connections.
- Force and Travel Verification: Once the sensors are calibrated, we reset the travel limits and force settings on your Craftsman, Genie, or Raynor opener to ensure the door does not exert too much pressure when it meets the floor.
Every single job we complete is backed by our 90-Day Done Right Promise. If the sensors are not right, we come back and fix it, in writing, without any arguing or extra fees. We have been doing this for over 42 years, and we stand behind our work.

FAQs - Sensor Calibration
Can I fix my own garage door sensors?
You can certainly check if the sensors are obstructed by a box or a broom, or if the mounting bracket has clearly been knocked loose, but we advise against attempting to splice wires or adjust internal logic board settings yourself. Garage door systems are under significant tension, and the door itself is a heavy, motorized object that can cause serious injury if it falls or closes unexpectedly. If a simple cleaning does not fix the issue, call us at (830) 689-6216 so we can handle the electrical and mechanical adjustments safely, including any needed Cable Repair.
Is it always the sensors when the door won’t close?
No, the sensors are just one part of the safety system, but they are the most common point of failure. If the sensors are aligned and clean, the issue could be a faulty logic board in your opener, a broken wire inside the wall, or an issue with the door’s force settings that may require Spring Repair. Our technicians are trained to diagnose the entire system, so we do not waste time replacing parts that are not actually broken.
Does the weather in New Braunfels really affect sensor performance?
Yes, it does. In the middle of a Texas summer, the heat can cause the aluminum tracks and brackets to expand, which shifts the alignment of the sensors by just a fraction of an inch, enough to break the beam and require Track Realignment. Additionally, the high humidity we often experience can cause corrosion on the older wire connections, leading to intermittent signal loss. We see these issues frequently and know exactly how to secure your brackets to withstand the local climate.
How quickly can you come out to fix my sensors?
We answer our phones 24/7 with a live person, and we prioritize service calls so we can typically get a technician to your home the same day. Because our trucks are stocked with a full inventory of parts, including sensors for all major brands like LiftMaster, Genie, and Chamberlain, we finish most jobs in a single visit. You will not be left waiting for us to order parts.
