We'd recommend having a qualified service technician perform a general maintenance service on the door ASAP, which would including tensioning the spring and reprogramming the limits. This spring works in tandem with the limits programmed into the opener to ensure smooth and safe operation. It is difficult to tell without inspecting the unit, but it sounds like the spring on the torsion axle above the door has lost most of it's tension, to the point where it is no longer able to fully raise the door.Īll garage doors should be service every 18-24 months to ensure the spring that carries the weight of the door is properly tensioned. Thanks for reaching out regarding the programming of your Gliderol opener.
