Garage Door Sensor Repair Coppell TX

This is the textbook symptom of a sensor problem. The opener needs the safety beam intact to allow downward travel, but opening does not require it. Check for blinking sensor LEDs, dirty lenses, or misalignment — or call us and we will diagnose it in minutes.

Please do not. Bypassing defeats the UL 325 entrapment protection and creates a serious crush hazard, especially for children and pets. It is also a code violation. If your door will not close, call Coppell Garage Door Experts at +1 (945) 404-0050 — most sensor issues are fixed same-day.

Sensor replacement is one of the most affordable garage door repairs — the parts are inexpensive and the job typically takes 30 to 45 minutes. Realignment alone costs even less. See our Coppell cost guide for details.

Almost certainly sunlight interference — low sun shining directly into the receiving sensor overwhelms the infrared beam. We fix this with repositioned sensors, sun shields, or upgraded sensor units with stronger beams and better filtering.

Sensors are sold and installed as matched pairs. Even if only one has failed, the pair is calibrated to work together, and the surviving unit is the same age. Replacing both ensures reliable beam strength and matched electronics.

Usually yes — quality universal photo-eye kits work with most openers made after the mid-1990s. Very old or proprietary systems may need OEM sensors or an opener upgrade. We verify compatibility by model number before installing anything.

Test the photo-eye reversal monthly (broomstick method) and have both the beam reversal and force reversal professionally verified during your annual tune-up. It takes seconds and it is the most important safety check on the door.

Yes — it is surprisingly common. Mice chew the low-voltage sensor wire, especially where it runs through attics or along garage walls. If your sensor faults are intermittent and the wire disappears into a wall cavity, rodent damage is high on our suspect list.
