Torsion spring

A tightly wound metal coil mounted above the garage door that counterbalances the door’s weight, letting it open and close smoothly. Torsion springs last 10,000–20,000 cycles (about 7–12 years in Albany) and are safer than extension springs because they stay in place if they break. If yours snaps, call us immediately—broken springs are the #1 garage door emergency and can cause serious injury.

Extension spring

Long, stretched springs mounted on either side of the door track that extend and contract to lift the door. They’re cheaper than torsion springs but wear out faster and can snap violently, sending metal flying. If you hear a loud bang near the sides of your door, it’s likely an extension spring failure—don’t touch it and call us right away.

Track

The metal rails (usually 14–16 gauge) that guide your garage door up and down. Tracks must stay straight and lubricated to prevent derailment. Albany’s freeze-thaw cycles can warp tracks over time, so check for dents or gaps every season. A misaligned track is a common cause of off-track doors—learn how to spot and fix it.

Roller

Small wheels (usually nylon or steel) that ride inside the track and support the door’s weight as it moves. Worn or cracked rollers make your door rattle or jerk. Albany’s humidity can cause rollers to swell or crack, so inspect them yearly. Replacing rollers is a quick, affordable fix that prevents bigger problems.

Opener

The electric motor that powers your garage door up and down. Modern openers use quiet DC motors and smart features like Wi-Fi control. If your opener hums but the door doesn’t move, it could be a stripped gear or dead capacitor—our technicians can diagnose it in under 30 minutes.

Photo-eye sensor

Safety beams mounted near the bottom of the door that stop it from closing if something (or someone) blocks the path. If your door reverses unexpectedly, the sensors might be dirty or misaligned. Albany homeowners often notice this issue after winter salt spray coats the lenses—clean them monthly to keep them working.

Limit switch

A small dial or digital setting inside the opener that tells the door when to stop opening or closing. If your door stops too early or won’t close all the way, the limit switch may need adjustment. Albany’s temperature swings can cause the switch to drift, so it’s a common tune-up item.

Weatherstripping

The rubber or vinyl seal along the sides and bottom of your garage door that blocks drafts, pests, and moisture. Albany’s wet winters and hot summers wear it out fast—cracked or missing weatherstripping lets in cold air and critters. Replacing it is a simple DIY job or a quick service call.

R-value (insulation)

A number that measures how well your garage door resists heat flow. Higher R-values (like R-12 to R-18) keep your Albany home warmer in winter and cooler in summer. If your garage feels like an icebox in February, upgrading to an insulated door can cut energy bills and reduce noise.

Cable drum

The round metal spool that winds and unwinds the lift cable as the door opens and closes. If the cable drum is cracked or the cable slips, your door can become unbalanced or fall. Albany’s humidity can corrode drums over time—inspect them during seasonal maintenance.

Bottom seal

The thick rubber strip at the very bottom of your garage door that seals the gap between the door and the driveway. A worn bottom seal lets water, snow, and pests inside. Albany homeowners should replace it every 2–3 years to prevent flooding or rodent intrusions.

Travel module

The brain of your garage door opener that controls speed, force, and safety features. If your opener behaves erratically—like stopping mid-cycle or reversing for no reason—the travel module may need reprogramming or replacement. Our technicians in Albany can reset it in minutes.

Trolley

The part of the opener that connects to the door and moves it along the track. If your door jerks or skips, the trolley might be loose or misaligned. Albany’s pothole-filled streets can jostle the trolley over time, so check its connection yearly.

Manual release

A red cord or handle inside the garage that disconnects the door from the opener in a power outage or emergency. Pulling it lets you open the door by hand. Always test it twice a year—Albany’s frequent storms make this a critical safety check.
