Garage Door Sensor Repair in Augusta, GA
If your door won’t close, reverses or the sensor lights blink, the photo-eye safety system is the first place to look. We align, rewire and replace sensors.
Photo-Eye Sensors: Your Door’s Safety System
Since the early 1990s, residential openers sold in the U.S. have been required to include an external entrapment protection system — in most homes, a pair of photo-eye sensors mounted low on each side of the door. One sends an invisible beam; the other receives it. If anything breaks the beam while the door is closing, the opener reverses.
When the sensors are dirty, bumped out of alignment, wet or have a damaged wire, the opener refuses to close or reverses. We diagnose and fix the sensor circuit — without bypassing the safety system.
- Sensor alignment and secure mounting
- Lens cleaning and sun-glare fixes
- Damaged or chewed wiring repair
- Replacement of failed sensors
- Auto-reverse and force testing
Signs of a sensor problem
- The door starts closing, then reverses back up.
- The door only closes if you hold down the wall button.
- One or both sensor indicator lights are blinking or off.
- The opener light flashes when you try to close the door.
- The problem happens at certain times of day — often when low sun hits the sensors.
Safe checks you can do
- Clear the path. Make sure nothing is between the sensors, including hanging items, leaves or a trash can lid.
- Clean the lenses with a soft, dry cloth.
- Check the lights. Most sensors have a steady light when aligned and a blinking or off light when not. Gently adjust the sensor bracket until the receiving sensor’s light is steady.
- Look at the wires running up the wall to the opener for staples through the wire, chewing or loose terminals.
- Shade them. If the problem happens in bright sun, the receiving sensor may be getting glare.
Never disconnect, remove or bypass the safety sensors, or tape them together to make the door close. They are a required safety system that protects children, pets and vehicles.

Augusta-specific causes
Morning and late-afternoon sun shining straight into a garage can blind the receiving sensor. Heavy summer storms can also drive water into low-mounted sensors and wire connections. Swapping the sensor sides or adding a sun shield often helps. Related problems: sensor lights blinking, won’t close after rain.

Sensor Repair FAQs
Why is my garage door sensor light blinking?
A blinking light usually means the sensors are misaligned, blocked, dirty, or there is a wiring problem. Clean the lenses and adjust alignment until the light is steady.
Can I bypass my garage door sensors?
No. The sensors are a required safety system. Bypassing them removes protection against the door closing on a person, pet or car.
Why does my door only close when I hold the wall button?
Most openers allow a manual override by holding the wall button when the sensors aren’t working. That means the sensors need attention — don’t rely on the override.
Can sunlight affect garage door sensors?
Yes. Direct sun on the receiving sensor can interfere with the beam, especially early morning or late afternoon. A sun shield or swapping sensor positions can help.
How high should the sensors be?
Follow your opener’s instructions; they are typically mounted no more than about six inches above the floor.
Do I need to replace both sensors?
Not always. If one sensor has failed, we may replace just that one if a compatible match is available, but often they are replaced as a pair.
