Off-Track Garage Door Reset: getting ready

A delivery van backed into the shop's overhead door this afternoon. The lower panel is pushed in, the track on that side is kinked, and the door is hanging unevenly with staff unable to close up for the night.

Worth answering before the call

Is a vehicle trapped inside the garage right now? Did a vehicle or anything else bump the door before this happened? Have the rollers been noisy, squealing or wobbling recently?

My door has springs along the sides, not above it. Is the reset the same?

The principle is the same but the sequence differs. With side springs the door is first opened all the way and clamped, because that is the position where the springs carry no load; the cables are then checked over their pulleys and evened up at the clips. The technician also checks that a containment cable runs through each spring, which stops a broken spring flying across the garage, and fits one if it is missing.

Should I lubricate the track to help the rollers?

No. The track is meant to be clean and dry; grease on the rail gathers dirt and makes the wheels slide rather than roll, which wears them faster and can contribute to a roller leaving the rail. Put a silicone spray made for garage doors, or a lithium grease, on the hinge pins, roller bearings and spring coils, wipe off the excess, and give the tracks nothing more than a damp cloth.
