Garage Door Won't Close All the Way? 7 Causes and Fixes
If your garage door starts closing and then reverses, the cause is almost always one of six things: dirty or misaligned photo eyes, debris or a bend in the track, worn rollers, a close-limit setting that's too sensitive, a fraying cable, or the door sitting out of spring balance. Photo eyes cause roughly seven in ten of these calls and are usually a free five-minute fix. The other five range from a $0 adjustment to a $549 cable or track repair. Work the checklist below in order, it's the same sequence we use on a truck.

Key takeaways
- Sensors first: photo eyes cause about 7 in 10 "won't close" calls and are the fastest thing to rule out.
- Free fixes: dirty lenses, misalignment, a stray obstruction, or a slightly-off limit setting cost nothing and take 5 to 15 minutes.
- Call-a-pro fixes: a bent track, a fraying cable, or a door out of spring balance are not safe to force closed yourself. Most run $85 to $549 installed.
- Local pattern: in Hampton Roads, salt air corrodes track hardware and bottom brackets faster near the water, so track and cable failures show up more here than in a typical inland market.
Why Won't My Garage Door Close All the Way? The Full Differential
Most "won't close" articles online only cover photo eyes, and that's the right first stop, but it's not the whole picture. Below is the same order we check on a service call: sensors, then track, then rollers, then the opener's own limit settings, then cable, then bottom seal, then spring balance. Most calls resolve in the first two steps.
1. Dirty, misaligned, or blocked photo eyes
Check: the two small units mounted about 6 inches off the floor on each side of your garage door opening. One sends an infrared beam, the other receives it. If either LED is off or blinking instead of solid, that's your answer.
Why it happens: a cobweb or smudge on the lens, a bumped bracket, a kicked broom handle, or a kid's soccer ball can knock the beam off by a degree, which is enough. UL 325 has required photo eyes on every residential opener sold since 1993.
Fix or call: wipe each lens with a dry, lint-free cloth, no cleaners or water. For misalignment, loosen the receiver eye's wing nut with your fingers, tilt it gently toward the other eye, and watch for the LED to go solid, then tighten. Check the low-voltage wiring at the opener's terminal block if a wire looks chewed or loose. This one is free and DIY-safe.
Blink pattern by brand: LiftMaster/Chamberlain flashes the opener light 10 times, Genie blinks the diagnostic LED twice, older Craftsman units stay full-brightness or flash with no rhythm.
2. Debris or a bent track
Check: look along both tracks for a dropped tool, leaves, or a toy wedged in the rail, and for any section that looks visibly bent or pulled away from the wall.
Why it happens: track brackets loosen with age, a car bumper or ladder bumps a track, and near the water salt air corrodes the mounting hardware faster than an inland home would see.
Fix or call: clear obvious debris yourself. A bent track is a call, not a DIY job, forcing the door can jump it off the track entirely. Our track and roller repair service handles this same-day.
3. Worn or dirty rollers
Check: pull the red release cord to disconnect the opener, then roll the door by hand and feel for grinding or resistance. A roller that looks flat-sided or cracked is worn out.
Why it happens: nylon rollers wear out after roughly 7 to 10 years of cycles, and steel rollers without sealed bearings dry out and grind.
Fix or call: garage-door-specific lithium grease (never WD-40 alone) buys time as a stopgap. Full roller replacement is a same-day track and roller service call.
4. Close-force or down-limit setting too sensitive
Check: if the door reverses right as it nears the floor, or right after the motor engages, rather than partway down, suspect the limit or force setting instead of the sensors.
Why it happens: openers drift out of calibration over months, especially after a power outage or a battery-backup swap.
Fix or call: most openers have small limit dials or a learn-button sequence in the manual, and a quarter-turn adjustment often fixes it. If you're not comfortable opening the opener head, this is an $85 diagnostic visit through our opener repair service. We rank this exact symptom, and four others, by how often we see them in our guide to why garage doors reverse before closing.
5. Fraying or broken lift cable
Check: look at the cable near the bottom bracket for frayed strands, rust, or a cable that has slipped off its drum.
Why it happens: cables wear at the drum edge over years of cycles, and salt air speeds up the rust on older doors near the water.
Fix or call: never operate a door with a visibly frayed cable. Both cables carry the door's full spring tension and can snap, letting the door drop. Call for same-day cable repair, this is not a DIY fix.
6. Worn bottom seal or an uneven slab
Check: look at the rubber seal along the bottom of the door itself. A torn or curled seal, or a gap where the slab has settled, can leave a visible inch that reads as the door "not closing all the way" even though the opener stopped normally.
Why it happens: rubber seals age out in about 5 to 8 years in this climate, and slabs settle gradually over time.
Fix or call: usually a same-day, low-cost fix. See our full bottom seal replacement guide for the DIY steps and when a slab issue means calling us instead.
7. Door out of spring balance
Check: with the opener disconnected, lift the door about halfway by hand and let go. A balanced door stays roughly in place. If it drops or shoots up, the springs are out of balance.
Why it happens: torsion springs lose tension gradually, most are rated for around 10,000 cycles before they need replacing.
Fix or call: never adjust or touch torsion springs yourself, the stored tension can cause serious injury. Call for same-day spring repair.
DIY-safe: cleaning or aligning photo eyes, clearing track debris, a small limit adjustment if you're comfortable, lubricating rollers. Call, don't attempt: a bent track, a fraying or broken cable, or a door out of spring balance. Those involve stored tension or a door that can fall, which is exactly what our licensed same-day team handles safely.
"Sensors get blamed for everything, and they're right most of the time. But out here near the water I see more track and cable calls than a tech inland would, because salt air eats the galvanized hardware faster than people expect. If the lenses are clean and aligned and the door still won't close, I'm looking at the track and the cable next, not guessing at the sensors again." David Yifrach, Owner · Seaside Garage Door Experts
