Federal law needs all garage doors made after January 1, 1993 to be geared up with an automated reverse function if it senses a blockage in the entrance. This function, typically called garage door sensing units, is created to conserve lives and prevent severe injuries from garage doors closing instantly. If it appears your sensing units are refraining from doing the task they were created to do, repair the garage door sensing units to separate and fix the issue triggering the sensing units to stop working.
1. Procedure the height of your garage door sensing units. Acquire a couple of cardboard boxes that are higher than the height of your sensing units.
2. Location package in the garage entrance, making certain package remains in front of the garage door sensing units. Press the button that closes the garage door on the garage wall or on your remote. If the sensing units are working, the garage door must instantly stop closing and go back to the employment opportunity. If the garage door cannot stop and squashes package, inspect the sensing unit positioning.
3. Take a look at both the garage door sensing units. Each sensing unit has actually an LED light on the outside of the sensing unit. If among the LEDs is blinking, the sensing units have to be straightened. Change the sensing unit with the blinking LED by tightening up the screw holding the sensing unit to the bracket, or flexing the bracket back into position. When you line up the sensing units properly, the LED stops blinking.
4. Open the garage door and get rid of the crushed box. Usage another box to break the infrared beam in between the two sensing units. Press the button to close the door. The door must stop and go back to the employment opportunity. If the garage door continues to close, inspect the sensing units for unclean lenses.
5. Tidy the lenses with a soft fabric. Dirt and spiderwebs can trigger the eyes to breakdown.
6. Check the door with another cardboard box. If the door still squashes package, ensure you do not have garden tools or boxes stacked near the sensing units. Inspect the sensing unit wires for damage, as a damaged or chewed wire will trigger the sensing unit to stop working. If you discover wire damage, change the sensing unit. If the sensing units went through water through rain, a sprinkler or a pressure washer, await the sensing units to dry and check the sensing units once again. If the garage door continues to close and squash package, the water might have shorted the sensing units, and they require changing.
