Garage Door Sensor Repair in Washington, DC, Maryland & Northern Virginia

Modern garage door openers are designed not to close when the safety sensors cannot confirm the path is clear. A door that won't close, closes partway and reverses, or closes only while you hold the wall button can point to misaligned, dirty, or failed sensors, but it can also point to incorrect opener force or limit settings, a track that is out of alignment, or a door that is out of balance. We inspect the sensors, opener settings, and door balance together to find the actual cause rather than assuming every closing issue is a sensor failure.

Before doing any work the technician checks the sensor indicator lights, alignment, bracket condition, and wiring, and confirms whether the door reverses correctly when an obstruction is present. If a sensor needs adjustment or replacement we explain what we found and provide an estimate for your approval before starting.

A safe visual check you can do at home is to confirm the area between the sensors is clear of objects, cobwebs, or anything that could block the beam. Do not bypass, disable, or tape over the safety sensors, and do not attempt to adjust the opener force, limit settings, springs, or cables yourself. Those components operate under tension or directly affect the door's safety behavior and should be handled by a trained technician.

It also helps to distinguish a sensor issue from other problems. If the door operates normally from the wall control but not from a handheld remote, the remote, its battery or programming may need attention. If the opener runs but the door does not move, the drive or door mechanism may be involved. We inspect the system to identify the cause.
