Safe procedure for manually operating an overhead door during power outages, operator failures, or emergencies, including re-engagement of the operator afterward
Warnings
If the door feels extremely heavy when attempting to lift manually, a counterbalance spring may be broken. Do not force the door open. A standard residential door without spring counterbalance weighs 150–400 lbs and can cause crush injuries if it falls.
Never allow children to operate the emergency release or manually operate the door.
When manually operating a door with a broken spring, be aware the door can slam down under its own weight if released. Keep all body parts clear of the door path.
This procedure is intended for end users during emergencies and for technicians to demonstrate to customers. It does not replace professional repair of the underlying issue.
If the door is stuck partially open and cannot be moved, do not leave it unattended and unsecured. Secure the premises and call for professional service.

Step 1
Never allow children to operate the emergency release or manually operate the door.
Locate the emergency release handle inside the garage. On most residential operators, this is a red handle hanging from a short rope attached to the trolley carriage on the operator rail. On commercial operators, there may be a chain hoist or a manual disconnect handle on the operator housing. Some doors also have an exterior emergency release accessible with a key from outside. If power is out, use a flashlight or headlamp to find the handle, and set up a step ladder if the release is mounted high.
