Garage Door Safety Sensors

Understanding Garage Door Safety Sensors

Does your garage door start to close and then bounce back up? If so the issue might lie in the garage door safety sensors. Your garage door safety sensors are a requirement on all automatic garage door openers that were manufactured and sold after January 1, 1993. Harry Jr’s Garage Doors specializes in garage door maintenance in Stockton, Lodi, Galt and surrounding areas. The Safety sensors are located at the bottom of the garage door track, 4-6 inches from the ground. You will have a receiving sensor on one side of the track, and a sending sensors on the opposite track.

The garage door safety sensors work by sending an infra-red beam between the two sensors. If something were to interrupt the beam while the garage door is closing – the opener will reverse and open again.  The sensors need to be properly aligned for the system to work.

If you are curious about the function of your garage door photo-eyes (and you should be, especially if you have children), the good news is that they are easy to test.  While the garage door operator is closing, simply walk to the sensor and interrupt the beam with your foot.  The opener should reverse, and once the door is fully open, the opener light will typically blink.  The the garage door doesn’t reverse, somethings wrong.  Time to get it fixed. Harry Jr’s Garage Doors services the Lodi, Stockton, Galt, and Elk Grove area.

I should note that for some garage doors,  you have to press and hold the button to get the door to close.  Holding the button down, disables the safety features of the garage door opener, so you won’t be able to test the light beam.  Of course, if you have to hold the button down, something is broken or misaligned and you should have had it fixed long ago!
