Torsion spring
The tightly wound spring mounted above the door that stores energy and does the heavy lifting to raise and lower it. Under high tension, it should only be serviced by a professional. If it shows up on your quote, Andrew Chen and Sons Garage Door Repairs LLC will walk you through it in plain language.
Extension spring
A spring that runs along the horizontal track and stretches to counterbalance the door's weight; common on lighter, single-car doors.
Track
The metal channels on each side that guide the door's rollers as it moves; bent or misaligned track causes binding and noise. Andrew Chen and Sons Garage Door Repairs LLC is glad to explain how this affects your Everett home during a free estimate.
Roller
The small wheels attached to the door's edges that ride inside the track, letting the door move smoothly. Our technicians point terms like this out to Everett homeowners as part of the work we do.
Opener
The motorized unit that automatically raises and lowers the door via a belt, chain, or screw drive, operated by remote or wall button. If it shows up on your quote, Andrew Chen and Sons Garage Door Repairs LLC will walk you through it in plain language.
Photo-eye sensor
Two aligned safety sensors near the bottom of the opening that reverse the door if something breaks the beam — a federally required safety feature. If it shows up on your quote, Andrew Chen and Sons Garage Door Repairs LLC will walk you through it in plain language.
Limit switch
The setting inside the opener that tells the door exactly how far to travel; misadjustment makes the door stop short or fail to seal. Our technicians point terms like this out to Everett homeowners as part of the work we do.
Weatherstripping
The flexible seal around the door's perimeter that keeps out drafts, rain, dust, and pests. Andrew Chen and Sons Garage Door Repairs LLC is glad to explain how this affects your Everett home during a free estimate.
R-value (insulation)
A measure of how well a garage door resists heat transfer; a higher R-value means better insulation and a more energy-efficient garage. If it shows up on your quote, Andrew Chen and Sons Garage Door Repairs LLC will walk you through it in plain language.
Cable drum
The grooved wheel at each end of the torsion shaft that winds and unwinds the lift cables to raise the door evenly. Our technicians point terms like this out to Everett homeowners as part of the work we do.
Bottom seal
The rubber gasket along the bottom edge of the door that compresses against the floor to block water, drafts, and debris. If it shows up on your quote, Andrew Chen and Sons Garage Door Repairs LLC will walk you through it in plain language.
Travel module
The component in newer openers that tracks the door's position and force, enabling accurate stopping and safety reversal.
Trolley
The carriage that connects the opener's drive to the door arm and pulls the door along the rail. Our technicians point terms like this out to Everett homeowners as part of the work we do.
Manual release
The red cord that disengages the door from the opener so it can be operated by hand during a power outage or emergency. Andrew Chen and Sons Garage Door Repairs LLC is glad to explain how this affects your Everett home during a free estimate.
