The Safety Reversing Sensors

The most common reason for the lights to flash on the garage door opener and the door not closing is that the safety reversing sensors are misaligned or obstructed; this is a safety feature of the garage door opener. Click here for instructions for aligning the safety sensors.

When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic beam. If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.

Your garage door opener is equipped with a Self Diagnostic feature to help you determine what the issue is. Based on the model of your garage door opener, your garage door opener will flash an LED next to your learn button or flash the UP and DOWN arrows a number of times to indicate the issue. If the opener has the up and down arrows use the table below to diagnose and resolve the issue.
