1. Broken Torsion Spring

Symptom:
Loud bang from the garage, door won't open, 2-inch gap visible in the spring above the door.
Cause:
Torsion springs are rated for ~10,000 cycles (about 7–10 years). Metal fatigue, rust from lake-effect humidity, and undersized springs all shorten lifespan.
Fix:
Replace the spring with a properly sized, oil-tempered or galvanized torsion spring matched to door weight (IPPT). Always replace BOTH springs on a dual-spring system — the second is days away from failing.
DIY-friendly?
No. A wound torsion spring stores hundreds of pounds of force. Wrong winding bars or technique cause serious injury. Call a tech.
Typical cost:
$220–$420 typical in Chautauqua County for a same-day spring replacement (parts + labor, both springs).

2. Snapped or Frayed Lift Cable

Symptom:
Door hangs crooked, one side dropped, cable dangling or coiled at the bottom of the track.
Cause:
Cables rust from road salt and Lake Erie humidity, fray at the drum, or snap after a spring failure overloads them.
Fix:
Replace both cables (always in pairs), inspect drums and bottom brackets, and re-tension the springs to spec.
DIY-friendly?
No. The bottom bracket holds the full weight of the door under spring tension — a wrong move there is the #1 cause of garage-door ER visits.
Typical cost:
$180–$320 including both cables and tension adjustment.

3. Door Off Track

Symptom:
Rollers popped out of the horizontal or vertical track, door stuck at an angle, often after a vehicle bump.
Cause:
Impact (bumper, snowblower), worn rollers, loose track bolts, or a broken cable letting one side drop.
Fix:
Unload spring tension safely, re-seat rollers, straighten or replace bent track sections, re-align and re-tighten.
DIY-friendly?
No — opening the door with rollers out can collapse the door on you.
Typical cost:
$150–$400 depending on track damage.

4. Opener Runs but Door Won't Move (or Reverses)

Symptom:
Motor hums, gear turns, but door stays put — or door starts down and immediately reverses.
Cause:
Stripped main drive gear, broken trolley carriage, mis-aligned safety sensors (the two little eyes near the floor), or a force-limit setting that's too low.
Fix:
Re-align sensors (solid LED on both), clean lenses, replace stripped gear/belt, or adjust travel & force limits. If the logic board is fried (common after lightning), swap the opener head.
DIY-friendly?
Sensor re-alignment and lens cleaning, yes. Gear or board work, no.
Typical cost:
$0 (sensor fix) to $120 (gear kit) to $450+ (new opener installed).

5. Loud, Grinding, or Squeaky Door

Symptom:
Screeching, banging, or grinding every time the door cycles.
Cause:
Dry rollers and hinges, worn nylon rollers, loose hardware, or a torsion spring screaming for lube.
Fix:
Replace steel rollers with sealed nylon ball-bearing rollers, lube spring and hinges with white lithium or silicone (NEVER WD-40), and tighten all lag bolts and track brackets.
DIY-friendly?
Yes — a $15 can of garage-door lube and a socket wrench solves 60% of noise complaints.
Typical cost:
$0 DIY, or $140–$220 for a full tune-up service call.

6. Door Frozen to the Concrete (Winter Special)

Symptom:
Opener strains, door won't budge off the slab — common after Dunkirk/Fredonia lake-effect storms.
Cause:
Melted snow refroze under the bottom weather seal. Forcing the opener tears the seal and can strip the opener gear.
Fix:
Pour warm (not boiling) water along the seal, or use a hair dryer / heat gun on low. Once free, clear ice from the slab and replace torn weather seal.
DIY-friendly?
Yes — but disconnect the opener first (pull the red cord) and lift by hand to confirm it's free.
Typical cost:
$0 DIY, $90–$160 for seal replacement.

7. Remote or Keypad Stopped Working

Symptom:
Wall button works, remote doesn't. Or keypad lights up but won't open.
Cause:
Dead 9V/CR2032 battery, antenna wire chewed/broken, opener in lockout mode, or remotes lost their pairing after a power surge.
Fix:
New battery first. Then re-pair the remote (LEARN button on the opener — usually 30-second window). Check antenna wire hanging from opener is intact.
DIY-friendly?
Yes, 5-minute fix.
Typical cost:
$5 battery; $40–$80 if you need a new remote/keypad.

8. Dented or Cracked Panel

Symptom:
Visible dent, crack, or hole in one section of the door.
Cause:
Backed into it, hail, or rotting wood on older Stanley/Wayne Dalton doors.
Fix:
Single-panel swap if the door model is still made (usually 8–15 years young). Older or discontinued doors usually need full replacement.
DIY-friendly?
No — panel removal involves disconnecting cables under spring tension.
Typical cost:
$280–$650 per panel installed; $1,200–$2,800 for a full new door.

9. Door Hard to Lift / Slams Down / Won't Stay Open

Symptom:
Door is heavy by hand, falls fast when released halfway, or drifts open on its own.
Cause:
Spring is mis-sized for the door weight. Common after DIY spring swaps using a generic spring instead of calculating IPPT (Inch-Pound Per Turn).
Fix:
Weigh the door, calculate correct IPPT using wire size, inside diameter, and length, then install the correctly rated spring. We use the SSC and DDM spring engineering calculators in-truck.
DIY-friendly?
No — and never trust a hardware-store 'universal' spring.
Typical cost:
$220–$420 for properly sized replacement.

10. Opener Closes Then Reverses Back Up

Symptom:
Door comes down, taps the floor (or doesn't), then goes back up.
Cause:
Close-force limit set too low, sensors slightly mis-aligned, or down-travel limit set past the floor.
Fix:
Adjust down-travel limit so door just touches floor, then increase close-force slightly. Re-align sensors so both LEDs are solid.
DIY-friendly?
Yes — adjustment screws are on the back of the opener head.
Typical cost:
$0 DIY, $90 service call.

A Word on Safety

Garage doors are the heaviest moving object in most homes — 130 to 400+ lbs held aloft by springs storing hundreds of pounds of torque. Spring, cable, and bottom-bracket work cause more emergency-room visits than any other home-repair task. When in doubt, call. Same-day service across Chautauqua County: (716) 475-9672.
