We don’t see a lot of foliage in Rancho Cordova, California, but we actually have a lot more than the rest of the country imagines. And while the splash of color is beautiful and that rustic smell of leaves is classic fall, leaves that fall to the ground become a nuisance pretty fast. In fact, they can actually interfere with your garage door sensors, preventing the door from closing. So if you find your door won’t close and keeps returning to the up position, look for piles of leaves around your sensors. Autumn may be running interference on your opener.
Required by law since the early 90s, sensors are used to automatically detect if something is in the way. This is designed to protect children and pets from injury. It also will stop the door from operating if something is in the way such as a car, a lawn mower or bike.
Other Things that Can Obstruct Sensors
Lots of things can actually interfere with your sensors. Cobwebs are common. Sometimes sunlight is a problem. You can get around this by securing cardboard or wooden shades around the top of the sensor to protect it from sunlight. Sometimes the sensors just need cleaned. A little soap and water might be the easiest garage door opener repair you’ve ever done.
