Quick answer
Monthly: place a 2×4 flat under the door and close it — it must reverse on contact. Then wave an object through the sensor beam while closing — it must reverse. If either fails, stop using the opener and book garage door opener repair.
Two simple tests confirm your door will not crush anything.
