Sensor Issues

Safety sensor alignment, cleaning, and replacement

Your door's safety sensors must be properly aligned and clear of obstruction to allow the door to close. Misaligned or dirty sensors cause the door to reverse unexpectedly or refuse to close entirely. We diagnose, clean, realign, and replace sensors as needed.

Common Questions

Sensor Issues: what homeowners ask

Why does my garage door reverse before closing?

A door that reverses or refuses to close while the opener light flashes almost always has a safety sensor issue — misalignment, a dirty lens, direct sunlight hitting the receiver, or a damaged wire. Entrancio diagnoses and realigns or replaces the sensors; a new safety sensor pair is $175 installed.

How much does it cost to replace garage door safety sensors?

An Entrancio safety sensor pair is $175, including installation and alignment by a technician. Simple realignment or cleaning is quoted upfront and often takes under an hour.

Can I bypass my garage door safety sensors?

You should not. Safety sensors are required by law on residential openers and prevent the door from closing on people, pets and vehicles. If they are faulty, repair or replace them rather than bypass them.
