Transcript
You press the button, and instead of a quiet hum, your garage fills with a grind, a rattle, or a squeal. Most of the time, the door is not dying — it is complaining. A grinding noise means metal on metal, usually a worn roller bearing skidding along the track. Spin each roller by hand — if it feels gritty or will not turn, replace it. A rattle means something got loose. Grab a socket wrench and tighten the track brackets and hinge bolts. A squeak is dry metal begging for lubrication. Use a silicone-based spray on the hinges, roller bearings, and spring. Do not use WD-40 — it is a solvent, not a lubricant. If you hear a loud bang from the spring area, stop immediately. A broken torsion spring is an emergency. Call a technician.
