How To Reset Garage Door After Pulling Red Cord?

Pulling the red cord on a garage door opener disengages the trolley mechanism, allowing you to operate the door manually. This feature is particularly useful during power outages or when the opener malfunctions.

However, once the issue is resolved, you must reset the system to reconnect the door to the automatic opener. Here’s how to fix garage door after pulling red cord.

Steps for Resetting the Garage Door after Pulling the Red Cord

To reset a garage door after pulling the red cord, close the door manually, then locate and pull the cord again to re-engage the trolley. Next, open the door fully to ensure it hooks onto the opener’s track. Garage Door Won’t Open or Close Properly Finally, use the automatic opener to test the door’s movement, ensuring it opens and closes smoothly. If issues persist, inspect the track for obstructions or consult a professional.

Step 1: Locate the Red Cord

The red cord, also known as the emergency release cord, hangs from the trolley that’s connected to the garage door’s track. It’s typically red to make it easily identifiable and has a handle at the end.

Ensure you can safely reach the cord without standing on tiptoes or using unstable objects to boost your height.

Step 2: Ensure the Garage Door is Closed

Before attempting to reset the system, make sure the garage door is completely closed to prevent it from crashing down during the process.

If the door is stuck open or partially open, manually close it carefully to avoid injury or damage to the door.

Step 3: Pull the Red Cord

Pulling the red cord disengages the trolley from the attachment point to the opener carriage, allowing manual operation of the door.

However, before proceeding with other maintenance tasks, it’s important to tell if garage door rollers are bad. If the door is already disengaged (as it would be if you’ve pulled the cord previously), skip to the next step.

Step 4: Lift the Garage Door

Lift the garage door manually until it’s fully open. If the door is balanced and functioning properly, it should stay open on its own.

If it doesn’t, there may be an issue with the door’s balance or the track system, which should be addressed before proceeding.

Step 5: Hold the Garage Door

With the door fully open, secure it in place or have someone hold it for you. This is a safety precaution to prevent the door from falling unexpectedly while you’re working on the reset.

Step 6: Release the Red Cord

With the door securely open, release the red cord by disengaging it completely. This might require a slight tug in the opposite direction of the initial pull to reattach the trolley to the opener carriage.

Step 7: Test the Garage Door

Now, use the automatic opener to close the door. Watch the door closely as it moves to ensure it re-engages with the trolley and moves smoothly along the track.

If the door does not close or if it stops prematurely, you may need to repeat the process or adjust the trolley mechanism.

Step 8: Observe the Door’s Movement

As the door moves, observe its path and alignment. The door should move seamlessly without jerking or halting.

If the door seems misaligned or makes unusual noises, stop the process and inspect the tracks and rollers for obstructions or damage.


Resetting your garage door after pulling the red cord is a straightforward process that can be done safely with careful attention to detail. It’s important to ensure the door is balanced and the tracks are clear to avoid potential hazards.

Regular maintenance and understanding how to properly engage and disengage your garage door from the automatic opener will keep it functioning efficiently and safely. If you encounter persistent issues or are unsure about the process, seeking professional help is advisable to prevent damage to the door or injury to yourself.
