Garage Door Components Explained: Know What to Replace and When

Whether you’re troubleshooting issues or performing regular maintenance, it helps to understand the key Garage Door Components that make it open and close. Knowing what each component does and when normal wear and tear requires replacement will save you from unnecessary garage door repairs down the road. Let’s take a closer look at the major components of a typical garage door.

Tracks

Tracks guide the wheels and keep the door moving smoothly up and down. Over time, tracks can develop bends or dents and need straightening or replacing. Check tracks annually for issues. Lubricate rollers and tracks as needed.

Rollers

Rollers are wheel-like components that ride along the tracks. Replace rollers if they look excessively worn down or no longer spin freely. Check rollers every 6-12 months and lubricate.

Hinges

Hinges connect door sections and allow them to fold up compactly. Inspect hinges annually for looseness, rust, or other defects. Tighten or replace as needed.

Springs

Springs provide the lifting power and are under high tension. Replace springs every 3-5 years or if one breaks. Left unreplaced, springs can snap with force.

Cables

Cables connect the door to the opener or manual mechanisms. Inspect cables yearly for fraying. Replace immediately if frayed to avoid snapping.

Panels

Panels are the sections that make up the door. Inspect panels for cracks, dents, or other damage yearly. Replace panels as needed to maintain structural integrity.

Weatherstripping

Weatherstripping seals the door perimeter to prevent air and moisture infiltration. Replace if cracked, peeling, or no longer creating a tight seal.

Understanding which Garage Door Components require regular inspection and maintenance helps avoid costly repairs down the road. With biannual lubrication and inspections of key parts, your garage door will operate smoothly for many years to come.
