How to Check your Garage Door Sensors
If you have a garage door that was made in the last ten years, chances are that they use a sensor system that will stop the door should there be some kind of obstruction under it. These work by displaying a beam from the two sides of the garage door, and the door stops if something breaks the beam. Generally, you should check your garage door sensors monthly. It takes just a few minutes and shouldn’t be any trouble at all.
First and foremost, look directly at the sensors after finding them to see if there is debris on either lens. This can coat the lenses and keep them from seeing the lens on the opposite side.
While you’re looking at the lenses, make sure they aren’t too loose; if they are loose, they may not line up properly and therefore not function as intended. You may need to replace these brackets if they will not stay put.
Next, you’ll want to ensure that there is electricity going to the unit. Look at the main power and fix this if you happen to notice that the lights for the sensors are not currently on. If they are not on, check the sensors’ wires. The connections need to be secure, and the wires will need replacement if they are frayed at all.
Peek at the inside the units to see whether the wires are snug in their positions. Ensure there is no debris on the inside, and check that the insides are dry.
If all else fails, you may need to replace your sensor units. This is necessary if none of the previous steps have allowed the door to work properly. If replacement doesn’t work, there may be a wiring problem that will require a repair professional.
