Tips for Fixing Your Garage Door

Q: When my garage door closes it immediately opens back up. How do I fix it?

A: These situations are often caused by the garage door sensors at the bottom corners of the door. As a safety device, the sensors transmit a laser to detect any obstructions. Start by ensuring that there are not any items blocking the sensors at the bottom of the garage door. If something is in the path of the sensors, the door will not close, and this includes objects as fine as a spider web. Also, these sensors can sometimes get inadvertently knocked out of alignment. Make sure the sensor is oriented in a level line parallel to the door sill and aimed at the opposing sensor. Also, make sure the door is not hitting anything when it comes down that could be causing it to reverse.

Sometimes if the door will not close all the way, the lights on the garage door motor will flash. The pattern of the flashes can indicate what the problem is. Check the garage door opener’s manual to see what the light flashing pattern means for your particular type of door.
