Lubricate and clean the garage door parts with oil every couple of years. Look at the moving parts of the garage door panels and overhead track system to be lubed.
Lubricate all moving parts with silicone or grease because it lasts longer, and it flows to those active areas - motor oil is fine.
Put some drops of oil on each hinge, bearing, roller, shafts, springs, rollers - but not the nylon wheels.
The extension or torsion spring should be lubricated or “wet.” As it dries, it creates greater wear when the coils compresses under high tension.
Clean the track, then use a light spray of silicone on each side of the track.
Use chain lube on chains, and grease on a screw drive.
Test your springs manually by disconnecting the opener, and a man can raise it with one arm.
The doors very rarely fall closed because there is no tension when the door is raised.
