How do I test the automatic reverse system?

Your garage door opener has two safety systems. The first and most apparent is the Safety Sensor System® which is located 4 to 6 inches above the garage floor on both sides of the door. To test the sensors, first open the door, then place a carton or an item that completely blocks the infrared beam of the sensors. When commanded to close, the door will not move more than an inch and the opener´s light bulb will flash for 5 seconds, equaling 10 flashes. Removal of the carton or item will allow normal operation. If the safety sensors become misaligned or obstructed, the garage door can be closed by pressing and holding the wall door control button until down travel is completed.

The second safety feature is a built-in automatic reverse system that will reverse upon striking an obstruction, provided the opener and door are installed and adjusted properly.

After adjusting the opener, always test the safety reverse system. We recommend repeating this test monthly.

Place a one inch board (or 2 x 4 laid flat) on the floor, centered under the garage door. Operate the door in the down direction. The door must reverse upon striking the board. If it does not, refer to your owner´s manual, call Texas Garage Door and Opener for a free estimate.
