Garage Door Sensors Replacement Services in San Francisco, CA

Safety is always the goal for garage door sensors, and proper alignment is crucial for optimal safety. If sensors are not aligned properly, the door may not move or could miss a collision. You may need a garage door opener repair.

Garage Door Malfunctions

A garage door that opens and closes smoothly is essential for any household. And if the garage doesn't provide enough clearance for the vehicle to get out or shuts down on your car, a person, or a pet, a perfect day can quickly turn sour, and emergencies can worsen.

Garage Door Sensor Alignment

Garage door opener sensors project a beam that allows the safe raising and lowering of a garage door. Proper lifting and shutting become impossible when the sensor falls out of alignment or debris obstruct the beam.

How Do I Know if My Garage Door Sensors Are Aligned?

One of the telltale signs that something is wrong with your door is if both sensors are not lighting up green when opened. This means that there may be a problem with the safety sensors, which will prevent the door from closing correctly.

If the LED lights on the sensors flash red, this typically indicates an alignment issue. You can return the sensors to working order with the help of a tape measure, a level, and a screwdriver or drill. After repositioning the sensors at equal height, reprogramming the door should resolve the issue. Because the exact process can vary with opener manufacturers, we recommend you consult the manufacturer's instruction or engage a qualified service technician to assist with the alignment.
