Diagnostic Codes for Garage Door Openers

The following article supports Security+ 2.0 Garage Door Openers manufactured after 2011 that utilize a yellow learn button and UP and DOWN adjustment arrows. The UP and DOWN adjustment arrows on the garage door opener flash a diagnostic code then pause before repeating, indicating a potential issue.

Note: For garage door openers that do NOT have UP and DOWN adjustment arrows, see article Diagnostic codes for garage door openers.
 

Diagnostic Code: 1 Up 1 Down

Why the error code is being displayed: The safety sensors are obstructed, misaligned, disconnected or there is a break in the wires for more than 4 seconds.

Door/Opener Behaviors: The garage door starts in the fully open or stopped position and when the garage door begins to close, it reverses to the open position or the garage door does not move and remains at the open position. The Garage Door Opener will not close, and the opener lights flash or click 10 times.

If no lights are installed, you will hear the opener click while attempting to flash the lights.
NOTE: Any garage door opener or replacement logic board manufactured after February 3, 2022, will no longer have this feature.
 

Symptoms/Resolution: Review the status of the LED on the Sending (Amber) and Receiving (Green) Sensors to determine the most common resolutions.
 

Amber LED off, Green LED off

• Sensors not installed: Install the Safety Sensors.
• Sensors not wired into the opener: Connect wires at the opener properly.
• Safety Sensor wires cut or broken to Sending Eye: Ensure wires are stripped back from insulation 7/16" and perform a tug test to ensure the wires are seated properly. Identify cut or broken wire for the Sending Eye by performing a short wire test by wiring the safety sensors with a foot of wire. Replace wires if the sensors work or replace sensors.

Amber LED on Solid, Green LED off

• Sensors Obstructed: Remove obstruction between the Safety Sensors.
• Sensors Not Aligned: Realign the Safety Sensors. The Receiving (Green) Sensor should be solid to indicate they are aligned.
• Safety Sensor wires cut or broken to Receiving Eye: Ensure wires are stripped back from insulation 7/16" and perform a tug test to ensure the wires are seated properly. Identify cut or broken wire for the Receiving Eye by performing a short wire test by wiring the safety sensors with a foot of wire. Replace wires if the sensors work or replace sensors.

• Sensors Obstructed: Remove obstruction between the Safety Sensors
• Sensors Not Aligned: Realign the Safety Sensors. The Receiving (Green) Sensor should be solid to indicate they are aligned.

Diagnostic Code: 1 Up 2 Down

Why the error code is being displayed: The wires are reversed or there is a short in the wires between the White and Black Terminals. Error is present for more than 4 seconds

Door/Opener Behaviors: The garage door starts in the fully open or stopped position and when the garage door begins to close, it reverses to the open position or the garage door does not move and remains at the open position. The Garage Door Opener will not close, and the opener lights flash or click 10 times.

If no lights are installed, you will hear the opener click while attempting to flash the lights.
NOTE: Any garage door opener or replacement logic board manufactured after February 3, 2022, will no longer have this feature.
 

Symptoms/Resolution: Review the status of the LED on the Sending (Amber) and Receiving (Green) Sensors to determine the most common resolutions.
 

Amber LED off, Green LED off
