Garage Door Opener Maintenance Checklist: Monthly, Seasonal, and Yearly Tasks

Most opener failures start small: a new noise, a weak remote, a photo eye that needs wiping. A short routine catches these before the door gets stuck.

Many openers last 10 to 15 years, according to House Digest. How long yours lasts depends on use and upkeep. The routine below takes minutes each month and needs no tools.

Every Month: A Five Minute Routine

Task	How	What a problem looks like	Our guide
Safety reverse test	Lay a 2 by 4 flat under the door and close it	The door does not reverse on contact	Monthly test guide
Photo eye check	Wipe both lenses, then pass a broom handle through the beam while the door closes	The door ignores the beam	Sensors guide
Watch and listen	Run the door once and listen	New grinding, humming, or jerky movement	Grinding guide
Remote and keypad check	Test each one from the driveway	Short range or no response	Remote guide
Look from the floor	Look at the springs, cables, and rollers. Do not touch them	A gap in a spring, or a frayed cable	Emergency repair

Every Season: Before Summer and Before Monsoon

Las Vegas hit 120 degrees on July 7, 2024, according to the National Weather Service. Heat is hard on electronics, batteries, plastic parts, and grease. Two seasonal habits help.

• Before summer: wipe dust from the tracks and the photo eye lenses, and replace remote and keypad batteries.
• Before monsoon season: add surge protection and test any backup battery. Our monsoon season guide has the full checklist.
• After a dust storm: wipe the photo eye lenses and run the safety reverse test.

Every Year: A Technician Checkup

Some jobs are not for homeowners. DASMA says springs, cables, and the brackets at the bottom corners are under extreme tension, so only a trained technician should adjust them. Our yearly checkup covers the safety reverse, photo eyes, drive parts, wall button, remotes, and door balance.

• Safety reverse and photo eyes
• Drive gear, chain or belt, and trolley
• Springs, cables, rollers, and tracks
• Door balance
• Remotes, keypad, and wall button
• Backup battery, if your opener has one

What to Leave Alone

• Do not adjust, lubricate, or touch springs, cables, or the bottom brackets.
• Do not change the force or travel settings without testing the safety reverse afterward. Chamberlain warns that improper adjustment can interfere with it.
• Do not open the opener housing, because mains power runs inside.
• Do not tape over or bypass a photo eye.
