  • To enable the efficient operation of the safety reversal system
  • To prevent damage to vehicles
  • To seal entrance from intruders – animals or thieves

Tips to Remember

Sensor Problems: For garage doors that stop when closing and reverses at a lower height, the problem is likely to be with safety sensors. Your initial assessment of the problem should involve checking the sensors on both sides of the opening. There could be something clogged in them or are obstructing them, preventing the door from closing completely.

Limit Screws: This is the most common cause of garage door height problems. Your garage door might be using nuts or plates or any other fastening mechanism. To adjust your garage door height, you will need to reset the points which the door stops when opening and closing.

Step by Step Process of Adjusting Garage Door Height

Step 1

Place your ladder underneath the garage door opener and ensure that it is stable.

Step 2

Find the limit adjustment screws on either side of the opener. These screws are usually made of plastic and labeled either “Up” and “Down” or “Open” and “Close.”

Step 3

If you want to increase the opening clearance, turn the Open and Up screws in a clockwise direction, increasing its opening allowance. Adjust the screws by one full turn.

Step 4

Climb down and test the garage door opener to see if the height has adjusted to your desired level. Use the garage door remote control unit to close and open the door at least three times to assess the height at which the door opens. If the height is not at the level you want, get back up the ladder and repeat Step 3 to adjust the limit switch further.

Step 5

For a door that is not closing completely, locate the Down or Close screw on the opener and adjust it in an anticlockwise direction. Check the closing performance of the door as in Step 4 above and keep tightening the close screw until the door closes tightly.

Step 6

For blocked sensors, clean the photoelectric eye and align the sensors that reverse the garage door. The eye needs to be aligned with the reflector on either side of the sensors. Test the door open again as in Step 4 to see whether the door works correctly.
