If these sensors are dirty or misaligned, your garage door opener may not function as intended. Follow these steps to ensure they are in optimal condition:

Clean the Safety Sensors

Over time, dust and grime can accumulate on the sensors, impairing their functioning. Use a soft, lint-free cloth to gently wipe the surface of each sensor, being careful not to scratch or damage the lens.

Ensure Proper Alignment

Alignment is critical for the sensors to work effectively. They need to be facing each other directly and be at the same level.

Misalignment can cause the garage door opener to falsely detect an obstruction and prevent the door from closing. Check their alignment and adjust as necessary, ensuring they are parallel to each other and the ground.
