Garage Door Pressure Sensor

Safety sensors are critical components of most automatic garage doors.

That s a job for the powerful motorized mechanisms. The sensors detect obstructions in the path of a closing garage door and prevent the door from closing when the path isn t. Refer to the owner s manual to determine which is which. These sensors are not door openers or closers though.

Garage doors may display a variety of symptoms if sensors need attention. If you garage door is lowering then reversing back to the open position there could. Again if someone or something contacts the sensor the door stops closing and pulls away. 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.

On the garage door motor there will be two knobs or dials to adjust the opener and the reverse sensor. Sensing edges provide entrapment protection for motor operated doors by offering an auto reverse or auto stop feature. 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.
