There is an emergency release cord hanging down from the rail on the opener. You will need to pull down on the handle to disengage the door from the opener. Once you have successfully pulled down the cord, this will release the door from the opener allowing you to manually operate the door until one of our technicians can get out to you. NOTE: Only garage door professionals can work on any and all garage door parts, as garage doors can be dangerous if not properly dealt with. Please call our office to schedule a service call and do not attempt any service work on your garage doors or motors.
