Your garage or gate electric rolling door needs basic maintenance to keep working year after year. Here's a simple routine that takes very little time.
Every month: Run the door and watch it. Is it smooth? Any jerking, pausing, or unusual noise? Look at the track on both sides. Is there dirt, leaves, cobwebs? Clean them out. Check that the safety sensors (if you have them) are clean and the indicator lights are steady.
Every three months: Unplug or disconnect the opener and try lifting the door manually. It should move with moderate effort and stay in place when you let go at the halfway point. If it's hard to lift or it drifts down, the springs need attention. While the opener is disconnected, lubricate the rollers, hinges, and the trolley rail with silicone spray. Don't overdo it. A light coat is plenty.
Check the weatherstripping along the bottom and sides. Torn or loose weatherstripping lets in water, dust, and bugs. Replacement strips cost very little and install in minutes.
Every six months: Look at the cables on each side of the door. They should be taut and not frayed. A frayed cable is a warning sign. It will fail, usually at the worst time. Check all the bolts and nuts you can see. Tighten loose ones. This includes the track mounting bolts, the opener mounting bolts, and the hinges.
Test the auto-reverse safety feature. Place a roll of paper towels or a piece of wood in the door's path. Close the door. It should reverse within a second or two of contact. If it doesn't, the down-force is set too high and needs adjusting. This is a safety issue. A door that doesn't reverse can crush a child or a pet.
Every year: Inspect the springs more carefully. Look for gaps between coils on torsion springs, or rust on any spring. Consider having a technician do an annual service if you're not comfortable with mechanical work.
Remote controls: Change the batteries once a year, whether they seem to need it or not. Low batteries cause intermittent problems that are hard to diagnose. Keep a spare remote programmed and stored inside the house. When a remote dies, you have a backup.
Lighting: If your opener has a light, replace the bulb before it burns out. LED retrofit bulbs designed for garage door openers don't interfere with the remote signal and last forever.
A little maintenance prevents most breakdowns. Fifteen minutes every three months is all it takes.
