Here are the most common problem indicators and solutions for common garage door openers. This LED light flashes a specific number of times. A garage door opener comes with an LED light indicator that is located on the back or bottom panel of the opener or underneath one of the light lenses if your opener has dual lights. If your problem has not been fixed, the self-diagnoses LED light indicator on your opener can help you determine a possible problem and solution for your opener. If aligned correctly, the green sensor will remain on and glow steadily. The photo eye with the amber light sends out the light, while the green sensor is the receiver. Loosen the wing nut holding up the photo eye and adjust them until both sensors are properly aligned. To fix this issue, first, locate the two photo eyes attached to your garage door and clean the lens using a soft microfiber cloth. The light from the opener blinks 10 times to warn you about misaligned photo eyes.

Perhaps the most common issue for many homeowners, if the safety sensors are not properly aligned the light will blink 10 times. Check for misplaced staples holding the wiring in place as they may also cause the wire to short.

You’ll need to hire a professional to replace the wiring entirely or check to see if the wire disconnected from the opener and reconnect it. If the opener cannot detect that the safety sensors are properly working or connected, then the opener lights will flash and the door will refuse to close.

The purpose of the safety sensors located on the bottom corners of your garage door is to automatically reverse your door if they detect motion underneath the door. It might be time for a maintenance check to determine if your wiring is to blame for the continuous blinking. If the light flashing persists, then the problem may be wire related. Simply hold down the lock button on the wall control for about two seconds to disengage the lock.
