To open a garage door with no power, pull the emergency release cord to disengage the opener, allowing you to lift the door manually. Ensure the door is properly balanced before lifting to prevent injury.

During a power outage, the emergency release cord (usually located near the opener) allows you to disconnect the garage door from the motor. Once disengaged, you can lift the door manually. It's important to regularly check the balance of the door to ensure it can be safely lifted without the assistance of the opener.
