Garage Door Sensor Repair in Jonesboro, AR — Same-Day Service

Garage door sensor problems in Jonesboro AR include blinking lights, door won't close, and door reversing unexpectedly. Most sensor issues are fixed same day by a licensed contractor with upfront pricing.

How Garage Door Sensors Work

Your garage door opener has two safety sensors mounted near the floor on each side of the door opening. One sensor sends an infrared beam across the opening and the other receives it. If the beam is broken by any object in the door's path, the opener automatically reverses the door to prevent damage or injury. This safety system has been required on all garage door openers manufactured since 1993. When the sensors are not working correctly, your door will not close properly.

Common Sensor Problems in Jonesboro AR

Sensor Light Is Blinking

A blinking sensor light means the two sensors are not aligned with each other. The amber sensor should have a solid light and the green sensor should also be solid. If either light is blinking, try cleaning the sensor lenses with a soft dry cloth. Then check that the sensor brackets have not been bumped out of alignment. Gently adjust the bracket until both lights are solid. If the lights continue to blink after cleaning and realignment, the sensor wiring may be damaged and a technician in Jonesboro AR should inspect the system.

Sensor Light Is Off

If one or both sensor lights are completely off, the sensors may not be receiving power. Check the wiring connections at the sensor and at the opener motor unit. If the wiring appears intact but the lights are still off, the sensor itself may have failed and need replacement. A licensed contractor can test the sensor circuit and replace the faulty component.

Sensor Being Hit By Sunlight

Direct afternoon sunlight can interfere with the infrared sensor beam, especially in Jonesboro AR where the summer sun is intense. If your door works fine in the morning but will not close in the afternoon, sunlight interference is likely the cause. A technician can install sensor sun shades or reposition the sensors slightly to eliminate the interference.

Sensor Wiring Damaged

Frayed or cut sensor wires can cause intermittent sensor failures. Inspect the wires running from each sensor to the opener. If you see visible damage, do not attempt to repair the wiring yourself. Call a professional to replace the damaged wiring and restore proper sensor function.

Can I Fix Garage Door Sensors Myself?

Sensor alignment and cleaning are safe DIY tasks. Gently adjust the sensor brackets until both lights are solid and clean the lenses with a soft cloth. However, if the problem involves damaged wiring, a failed sensor, or sunlight interference requiring repositioning, a licensed contractor should handle the repair.
