Annual general garage door maintenance ensures the correct operation of the door, prevents the mechanism from becoming noisy, and assures the safety of anyone who uses it. It is necessary to perform a monthly visual inspection for signs of wear and damage. Pay particular attention to the door springs, cables, rollers, pulleys and mounting hardware. Monthly tests of the reversing mechanism, photo eye, edge sensor and closing force settings are important to prevent accidents and entrapment.
To perform annual maintenance of a garage door, unplug the automatic door opener, and clamp the roller tracks bellow the roller with pliers if the door is open.
Inspect and tighten the roller brackets and the bolts. Nylon and steel rollers present signs of wear that are easy to spot and must be replaced. Nylon tends to crack and chip, and the steel components have the potential to bend. Roller replacement involves reinstalling the roller brackets, but never remove the bottom bracket. The cable attached to it is under extreme tension and could cause an accident. Inspect and clean the lift cable. If damaged is present, call a professional to replace it.
Consult the door manual to see if the opener need lubrication. Use white lithium grease to lubricate the chain or screw on the opening. Lubricate overhead torsion and extension springs to prevent corrosion, without wiping off excess lubricant. Replace the weather seal, and test the door. Call a professional if you are ever in doubt.
