Cold morning
On a sub-zero dock morning, the first lift can reveal a broken high-cycle torsion spring or a lift cable that has let go. The motor may run while the heavy sectional door stays down, leaving a delivery outside. Call with the door stopped; don't keep cycling the operator. Keep staff and vehicles away from the opening. Your technician examines the springs, lift cables and drums, then explains the repair and checks the door's balance before returning it to use.
