How to manually open a roller garage door?


A roller garage door is a popular choice for many homeowners due to its convenience and space-saving design. However, there may be instances when you need to manually open the door, such as during a power outage or if the automatic opener malfunctions. In this article, we will guide you through the steps on how to manually open a roller garage door.

Step 1: Disconnect the Garage Door Opener

Before attempting to manually open the roller garage door, it is crucial to disconnect the garage door opener to prevent any accidents or damage. Locate the emergency release cord or lever, which is usually red and hanging from the opener rail. Pull down on the cord or lever to disengage the opener from the door.

Step 2: Identify the Manual Operation Mechanism

Once the opener is disconnected, you need to identify the manual operation mechanism of your roller garage door. This mechanism can vary depending on the specific type and model of your door. Common manual operation mechanisms include a chain hoist or a crank handle.

Step 3: Using a Chain Hoist

If your roller garage door is equipped with a chain hoist, follow these steps to manually open it:

Materials used: Ladder (if necessary), gloves (optional)

1. Position a ladder beneath the chain hoist, if needed, to reach it comfortably.
2. Grab the chain hoist handle firmly and pull it downward to release the brake mechanism.
3. Begin pulling the chain hoist downward, using a hand-over-hand motion. This will start lifting the door.
4. Continue pulling until the door is fully open. Ensure the door is securely locked in the open position before letting go of the chain hoist.

Step 4: Using a Crank Handle

For roller garage doors with a crank handle, follow these steps to manually open the door:

Materials used: Crank handle

1. Locate the crank handle socket, typically located near the center of the door.
2. Insert the crank handle into the socket and ensure it is securely attached.
3. Rotate the crank handle in a clockwise direction to lift the door.
4. Keep turning the crank handle until the door is fully open.
5. Once the door is open, remove the crank handle from the socket and store it in a safe place.


Knowing how to manually open a roller garage door can be invaluable in situations where the automatic opener is not functioning. By following the steps outlined in this article, you can safely and effectively open your roller garage door manually. Remember to always exercise caution and consult the manufacturer’s instructions for your specific door model.
