How to Disengage Garage Door Openers for Manual Operation

Emergency Release Cord

There are circumstances where you have to dis-engage your garage door opener from your door. The most common is when your opener is either without power or it’s failing to perform its’ normal operations.*

VERY IMPORTANT: The door MUST be closed to do this. If you cannot close the door, DO NOT attempt. The garage door could drop hard and fast, and either hurt someone or damage the garage door or structure of your garage.

Trolley

First, locate the “release cord” that is hanging off the opener rail close to your door. This is usually a red cord with a pull handle (somewhat like a lawn mower). Pull cord down and back (towards motor) with a small amount of force. You will feel it disengage, as well as, visually see the small spring on the lever open up. You can now open and close your door manually. If you cannot lift the door once the door is dis-engaged from the opener, stop immediately and call a professional- you likely have a broken spring.

To re-engage opener, push the wall console button to start the motor, and allow it to travel until you can see mechanism on the bottom of the rail (known as the “Inner Trolley”). Now locate the piece that slides along the bottom of the opener rail as the opener chain, belt, or screw is turning. This is the part that needs to be re-engaged to the carriage, trolley, or other mechanism that attaches the black elbow looking tow arm to the opener rail to raise the garage door. On some models, the door should reconnect automatically when motor stops its cycle. You will hear it “click” in place- this is usually for a belt-driven opener. For most other garage door openers, you will have to either pull down on the red emergency release cord, or down and towards the lights on the motor unit until you hear a click- or see a tab flip towards the motor lights on the opener unit on the ceiling. Then, you can either manually raise or lower the garage door until the outer trolley meets the inner trolley, or you can press the wall button and allow the opener to re-engage itself. Note that doing it manually is much safer, is less likely to cause damage, and is more likely to solve the issue. Please note that there are limit and force settings that may need to be re-adjusted before normal operation can continue.
