If you’re having an issue with your garage door staying closed, or it pops up as its tracking downward, you may have a blocked sensor, something in the way of the sensor field, or something that has nudged the sensor out of position (such as a bike, box, trashcan, or garden tool.). Here are some things to check to get your garage door operating correctly.
Sensor blockage. Check to see if anything is blocking your sensors.
Sensor alignment. Check to see if a sensor is out of position/misaligned. Here is how to make sure sensors are aligned:
- There are two sensors with LED indicators. Both need to be on and steady.
- Loosen the wingnut on the sensor so you can adjust it up or down.
- Adjust the sensor until both LED’s glows steady.
For more information, this video from our manufacturing partner Lift Master shows how to do the alignment.
