Safety sensors are misaligned or were momentarily obstructed. Realign both sensors to ensure both LEDsare steady and not flickering. Make sure nothing is hanging or mounted on the door that would interruptthe sensor's path while closing. Download the user manual here and refer to page 35-36 for more troubleshooting instructions.
