Garage door pressure sensor.

These sensors are not door openers or closers though. The bottom sensing edge stops and reverses the door upon contact with an obstruction. If any object blocks the path of the infrared sensors the garage door opener will not activate or will reverse if operating. The second line of defense is a set of infrared sensors which should be mounted 4 to 6 above the floor on each side of the garage door frame.

Pressure sensors attach to the bottom of the garage door. Garage door openers manufactured after 1993 include sensors to prevent a door from closing on a child or pet. If you garage door is lowering then reversing back to the open position there could. That s a job for the powerful motorized mechanisms.

Again if someone or something contacts the sensor the door stops closing and pulls away. Garage doors may display a variety of symptoms if sensors need attention. Safety sensors are critical components of most automatic garage doors. On the garage door motor there will be two knobs or dials to adjust the opener and the reverse sensor.
