What does the flashing LED next to the learn button mean? Your garage door opener is programmed with self-diagnostic capabilities. The diagnostic LED next to the learn button will flash a number of times, then pause before repeating, signifying it has found a potential issue. The Diagnostic Chart is below. 1 or 2 Flashes - One or both of the LEDs on the safety reversing sensors do not glow steadily. One flash means there is a broken or disconnected wire to a safety reversing sensor. Two flashes means a wire to a sensor is shorted out or a black/white wire is reversed. Inspect the sensor wires for a short (staple in a wire), incorrect wiring polarity (black/white wires reversed), broken or disconnected wires; replace or reattach as needed. 3 Flashes - The LED is not lit on the door control. Inspect the door control wires for a short (staple in wire), and replace as needed. Disconnect wires at the door control, then touch the wires together. If the garage door opener activates, replace the door control.

If the garage door opener does not activate, disconnect door control wires from the motor unit. Momentarily short across the red and white terminals with jumper wire. If the garage door opener activates, replace the door control wires. 4 Flashes - The safety reversing sensor sending LED glows steadily, and the receiving light is dim or flashing. The safety reversing sensors are slightly misaligned. Loosen the wing nut on the receiving sensor, clean the lens, realign the sensor until it glows steadily, then tighten the wing nut and secure the brackets. Verify the door track is firmly secured to the wall and does not move. 5 Flashes - This is a miscellaneous code. Additional symptoms will help to identify the issue. If the opener is not moving at all and you hear a short hum, look for a physical obstruction and remove it, or check if the trolley is stuck on the stop bolt. See How do I get the trolley off the stop bolt?. If the door is moving more than 6-8 inches it is likely that a force adjustment is needed.
