Garage Door Sensor Repair in Bee Cave, TX

Start Your Sensor Repair Here

Good Golly Garage Doors realigns and repairs garage door safety sensors in Bee Cave, TX, so your door reverses when it should. These sensors, often called photo eyes or safety eyes, are a required safety feature on all modern garage door openers. They project an invisible beam of light across the door opening, just a few inches off the floor. If anything breaks that beam while the door is closing, the opener immediately reverses the door to prevent it from closing on a person, pet, or object. When these sensors are misaligned or failing, your garage door might refuse to close at all, or it might reverse for no apparent reason. Our job is to find the cause of the problem and restore this critical safety function.

The Bee Cave Pattern We See with Garage Door Sensors

In Bee Cave, we see specific issues that affect garage door sensors. The most common problem from December through February is mountain cedar pollen. Bee Cave is in the heart of cedar country, and the pollen is often thick enough to coat the sensor lenses. This film of pollen blocks the infrared beam, making the opener think something is in the door's path. A simple cleaning often solves the problem, but if it happens repeatedly, the buildup can damage the lens surface.

The local housing style also plays a role. In neighborhoods like Falconhead and The Homestead, many homes feature large, heavy, three-car garage doors made of wood or composite to match the Hill Country architecture. These heavier doors can create more vibration as they run. Over time, this constant shaking can knock the small sensor brackets out of alignment. We also see issues from the Texas sun. The hard western sun that many Bee Cave homes face can make the plastic sensor housings and wire insulation brittle and cracked, leading to electrical failures.

Parts We Inspect for a Sensor Problem

When your garage door sensors are acting up, we follow a consistent process to diagnose the issue. It is not always a simple matter of realignment. We inspect the entire safety system from one side of the door to the other.

• Sensor Lenses and Housings: First, we check the lenses for dirt, pollen, or scratches. We clean them carefully. We also inspect the plastic housings for cracks or sun damage that could let moisture inside and harm the electronics.
• Mounting Brackets: The sensors are held in place by metal brackets. We check to see if they have been bent, hit by a car or lawnmower, or shaken loose from the wall or track. A solid, secure mounting is essential for reliable alignment.
• Alignment and Indicator Lights: Each sensor has a small LED light. One is the sender and one is the receiver. If the lights are lit steadily, the sensors are aligned and working. If one is flickering or off, it indicates an alignment problem or a power issue. We carefully adjust them until the beam is perfectly straight and the lights are solid.
• Wiring: We trace the low-voltage wires from each sensor all the way back to the opener motor. We look for frayed insulation, kinks, or staples that might have been accidentally driven through the wire. We also check the connection points at the back of the motor, as these can sometimes become loose or corroded.

Cost Drivers and Choices for Sensor Repair

The solution to a sensor problem depends on what we find during the inspection. You have a few choices, and we can explain the pros and cons of each.

A simple realignment is the most common fix. This involves cleaning the lenses, adjusting the brackets, and confirming that the indicator lights are solid. This is a straightforward adjustment. If your sensors are just dirty or have been bumped slightly, this is usually all that is needed.

A full sensor replacement is necessary when the units themselves have failed. If the plastic is cracked, the internal electronics are bad, or the wiring is damaged beyond a simple fix, we will recommend installing a new set of sensors. This ensures a reliable, long-term solution. Trying to repair heavily damaged sensors is often not practical.

Sometimes, the issue is intermittent. We can show you how to check the indicator lights yourself and how to keep the lenses clean, especially during cedar season. If a problem persists after a cleaning and visual check, it is best to have a professional take a look. Continuing to use a door with faulty sensors can be a safety risk. Our work is part of our complete garage door repair service, aimed at keeping your system safe and reliable.
