# How to open a garage door in a power outage Updated: 2026-10-24 · https://pros411.com/en/guides/garage-door-repair/open-garage-door-manually ## Short answer To open a garage door in a power outage, first make sure it is all the way down and both springs are in one piece. Pull the emergency release cord, the red handle hanging from the opener rail, straight down. Then lift the door slowly by its handle, with your hands away from the joints between panels. When the power is back, close it and press the button. > Safety first: Pull the release cord only with the door all the way down. If the door is open, or a spring has a gap, it can slam down. Never run a generator in the garage, even with the door open: carbon monoxide builds up fast. ## How to open a garage door by hand when the power is out ![Cartoon garage door in the dark during a power outage, with a phone flashlight on the emergency release cord](https://pros411.com/img/guias/open-garage-door-manually.webp) 1. **The power is out and the button does nothing.** Without power, the opener holds the door shut. You can open it by hand, but only after two quick checks. 2. **Door all the way down, springs in one piece.** Use your phone’s flashlight. Each spring above the door should be one solid coil. A gap means stop: the door is too heavy to lift. 3. **Pull the release cord straight down.** It is the red handle hanging from the opener rail. Pull it down firmly until the door lets go of the opener. You may hear a click. 4. **Lift the door slowly by the handle.** Use the handle or the bottom edge, with your hands away from the joints between panels. If it feels very heavy, lower it and call. 5. **Power back? Let the opener reconnect.** Close the door by hand and press the wall button. The opener moves along its rail and clicks back into place. ## While the opener is disconnected The door does not lock by itself in manual mode. Close it when you are done and use the slide lock on the inside, if your door has one. Unlock it again before you use the opener, or the motor will strain against it. ## If it won’t reconnect Most openers catch the door again the next time they run. If yours does not, look at the label on the release cord or the manual. Some models need the cord pulled toward the door first, then a press of the wall button. ## What not to do - Do not pull the release cord with the door open or partly open. - Do not lift the door if a spring is broken or a cable hangs loose. - Do not run a generator or a car with the garage closed. ## When to call a garage door technician - The door is too heavy to lift, or it drops when you let go. - A spring has a gap or a cable is loose. - The opener won’t reconnect after the power is back. - The door sticks or binds as you lift it.

With the door fully closed, pull the emergency release cord straight down, then lift the door slowly by its handle. Check first that both springs are in one piece. ### Is it safe to pull the emergency release on a garage door? Yes, with the door all the way down and the springs in one piece.
