- Test the door operation to ensure the blinking light has stopped.
2. Obstructions in the Door Path
Another common reason for a blinking light is an obstruction in the door’s path. This could be anything from a toy to a tool left on the floor.
How to Clear Obstructions
- Inspect the area beneath the garage door for any items that may be blocking its path.
- Remove any obstructions you find.
- Try operating the door again to see if the blinking light persists.
