How to Find Your Garage Door Model Number, Brand, and Specifications (Complete Guide for Utah Homeowners)

Your garage door model number is usually on a label or sticker on the inside of the door, near the top panel or along the vertical edge. Opener model numbers are on the motor unit housing on your ceiling. If labels are missing or unreadable, a professional can identify your door by measuring, inspecting panel profiles, and checking hardware. Advanced Door helps Utah homeowners identify their garage door brand, model, and specifications every day – call (844) 971-3667 for help from a locally-owned company with a lifetime warranty on parts and labor, 4.9 stars, and same-day service across Utah.

Why You Need Your Garage Door Model Number and Specifications

Most homeowners never think about their garage door model number until something breaks. Then suddenly, the technician on the phone asks “what brand and model is your door?” and you have no idea. That question is not just small talk. Your model number determines which replacement parts fit, what spring specifications are correct, whether your warranty is still valid, and how much your repair will cost.

Knowing your garage door and opener specifications before you need a repair saves time, money, and frustration. A technician who arrives knowing your exact model can bring the right parts on the first trip instead of making a second visit. Insurance adjusters need model information to process claims accurately. And if you are comparing repair estimates from different companies, having your specifications ready ensures every company is quoting the same work.

This guide covers every major garage door and opener brand, shows you exactly where to find identification labels, explains what the numbers mean, and gives you a system for recording this information so you always have it when you need it.

Where to Find the Label on Your Garage Door

Every garage door manufactured in the United States carries an identification label. The challenge is that manufacturers put these labels in different locations, and over time labels can fade, peel, or become covered by dirt and insulation. Here is where to look for each major brand.

A few tips for locating stubborn labels: On insulated garage doors, the label is sometimes partially covered by the insulation backing. Gently lift the edge of the vinyl backing to check underneath. On older doors, labels may be covered by paint if the door was repainted at some point. On wood garage doors, look for a metal plate or sticker near the top rail rather than on the panels themselves.

How to Read Garage Door Model Numbers by Brand

Once you find the label, you need to know what the numbers and codes actually mean. Each manufacturer uses a different coding system. Here is how to decode the most common brands you will find on Utah homes.

Clopay

Clopay is the largest residential garage door manufacturer in the United States. Their model numbers typically follow a pattern that tells you the collection, design, insulation level, and color. For example, a model like “GD2SU-SW” breaks down to: GD = Gallery collection, 2 = design number, S = short panel, U = Ultra-Grain finish, SW = color code. Clopay organizes their doors into collections including Classic, Value Plus, Coachman, Gallery, Canyon Ridge, Avante, and Modern. Knowing your collection helps your technician quickly identify panel profiles, available replacement parts, and replacement options.

Amarr

Amarr uses a series-based numbering system. Their residential lines include Stratford, Lincoln, Heritage, Classica, and Hillcrest. A model number like “2500” tells you the series (2500 = Stratford collection, a basic steel raised panel). Higher series numbers generally indicate higher-end lines with better insulation and construction. The label also shows the panel thickness, insulation type (polystyrene or polyurethane), and R-value.

C.H.I. Overhead Doors

C.H.I. uses a four-digit model system. The first two digits indicate the series and construction, while the remaining digits identify the design. For example, model 2283 means a 2200 series (stamped steel) in design 83 (flush panel). Their residential series include 2200 (stamped steel), 2250 (sandwich construction), 4200 (carriage house), and 5200 (overlay carriage house). C.H.I. labels also show the steel gauge, insulation type, and wind load rating.

Wayne Dalton

Wayne Dalton uses a model number system where the series indicates the product line. Their Classic Steel models use numbers like 8000 (basic), 8100 (insulated), 8200 (premium insulated), 8300 (carriage house), and 8500 (contemporary). The ThermoMark rating on Wayne Dalton labels is their proprietary insulation measurement. Wayne Dalton also marks their doors with a unique color code that helps match replacement panels exactly.

Martin Door (Made in Utah)

Martin Door is manufactured right here in Salt Lake City, making it a locally-produced option for Utah homeowners. Their model numbers reference the door style and construction. Common Martin Door models include the Pinnacle, Olympus, Cornerstone, and Athena series. Because Martin Door is a smaller manufacturer, their labels tend to be more straightforward, listing the model name, dimensions, and build date. If you have a Martin Door and need parts or support, their SLC manufacturing facility means faster parts availability and direct manufacturer support for Utah customers.

Overhead Door Corporation

Overhead Door uses a model naming system with both letters and numbers. Their Thermacore series (models 190, 195, 490, 495) indicates the insulation level and construction. Courtyard Collection models use a “C” prefix. The Overhead Door brand stamp is distinctive – a red ribbon logo – making their doors easy to identify even without reading the full label. Their labels typically include the model, serial number, manufacturing date, R-value, and wind load certification if applicable.

How to Find Your Garage Door Opener Model Number

Your garage door opener has its own model number that is separate from your door’s model number. You need the opener model to order replacement remotes, keypads, gears, logic boards, and other parts. Here is where each brand puts their identification information.

LiftMaster and Chamberlain: Same Company, Different Labels

LiftMaster and Chamberlain are both made by the Chamberlain Group. LiftMaster is the professional-grade line sold through dealers, while Chamberlain is the retail version sold at home improvement stores. Despite being the same parent company, they use different model numbers. A LiftMaster 8550W and a Chamberlain B6765T are functionally similar openers but have completely different part numbers for remotes, keypads, and internal components.

The easiest way to identify a LiftMaster vs Chamberlain is the Learn button color. LiftMaster models from the last 15 years use purple, yellow, orange, or green Learn buttons. Chamberlain uses similar colors but their housing design differs. If you see a Chamberlain Group logo but are not sure which brand you have, the model number prefix will tell you: LiftMaster numbers typically start with a letter-number combination like 8550, 84501, or?”87504, while Chamberlain uses letter prefixes like B970, B4655T, or C2405.

Genie Openers

Genie uses model numbers that indicate the drive type and features. Their current residential models include the SilentMax (belt drive), ChainMax (chain drive), and StealthDrive (wall-mount). Older Genie openers used different naming conventions. A common older model is the Genie Pro Max (screw drive), which stopped production around 2017 but is still found on many Utah homes. The Genie model number also tells you whether your opener uses Intellicode 1 (dip switches, pre-1997) or Intellicode 2 (rolling code, 1997-present) security technology.

Craftsman Openers

Craftsman openers use a distinctive model number format: 139.XXXXX, where the 139 prefix identifies it as a garage door opener in Sears’ numbering system. Since Sears went through bankruptcy, finding Craftsman-specific parts has become increasingly difficult. The good news is that many Craftsman openers were actually manufactured by the Chamberlain Group, which means some LiftMaster or Chamberlain parts may be compatible. Your model number helps a technician determine whether compatible parts exist or whether a full opener replacement makes more sense.

Linear Openers

Linear uses straightforward model names. Current residential models include the LDCO800 and LDCO850 (DC-powered), LDO33 and LDO50 (AC-powered), and the HAE00002 (wall-mount). Linear uses 310 MHz MegaCode technology, which is different from the 315 MHz or 390 MHz frequencies used by LiftMaster/Chamberlain and Genie. This means Linear remotes and keypads are brand-specific and cannot be swapped with other brands.

How to Identify Your Spring Type and Size

Your garage door springs are one of the most critical components to identify correctly. Using the wrong spring size can cause the door to be dangerously unbalanced, damage the opener, or even cause the spring to fail prematurely. There are two main types of springs, and each has different identification methods.

Torsion Springs vs Extension Springs

Torsion springs mount on a metal shaft (torsion bar) directly above the garage door opening. They look like large coiled springs running horizontally across the top of the door. Extension springs mount along the horizontal tracks on either side of the door and stretch when the door closes. If you are not sure which type you have, this guide to how garage doors work shows both systems in detail.

How to Identify Torsion Spring Specifications

A torsion spring has three key measurements that determine whether a replacement will work correctly:

• Wire size (gauge): The diameter of the wire used to make the spring coils. Common sizes range from .192 to .273 inches. You can estimate this by measuring 10 or 20 tightly wound coils and dividing by the number of coils measured.
• Inside diameter: The diameter of the space inside the coils when the spring is relaxed. Most residential torsion springs have a 1-3/4 inch or 2 inch inside diameter.
• Overall length: The length of the coiled section of the spring (not including the winding cones on each end).

You also need to know whether you have a left-wind or right-wind spring (or both in a two-spring system). Standing inside the garage looking at the torsion bar, a left-wind spring has coils that wind clockwise going from left to right, and a right-wind spring winds counterclockwise. Most two-car garage doors use one of each. Understanding spring specifications helps you have a more informed conversation with your technician about replacement costs and the replacement process.

Extension Spring Color Codes

Extension springs use a color-coded system to indicate their lifting capacity. The color is painted on the end of the spring or on a tag. Here are the standard color codes:

• Tan: 100 lbs
• White: 110 lbs
• Green: 120 lbs
• Yellow: 130 lbs
• Blue: 140 lbs
• Red: 150 lbs
• Brown: 160 lbs
• Orange: 170 lbs
• Gold: 180 lbs
• Light Blue: 190 lbs

The correct spring weight depends on your door’s weight, which is determined by the door’s size, material, and insulation. Using a spring rated for the wrong weight creates a dangerous imbalance. Your door’s balance depends entirely on matching the spring to the door’s actual weight.

What to Do If Your Label Is Missing or Unreadable

It is common for labels to be missing, especially on older doors or doors that have been repainted. Here are several methods to identify your door without a label.

Visual Identification

An experienced technician can often identify a garage door brand and model just by looking at the panel profile, hinge design, and construction details. Each manufacturer uses distinctive panel shapes, embossing patterns, and hardware.

• Panel profile: The shape of the raised or recessed sections on each panel is unique to each manufacturer and model line. Raised panel, flush panel, carriage house, and contemporary designs each have brand-specific profiles.
• Hinge style: Some manufacturers use proprietary hinges with their logo stamped into the metal.
• End stile design: The vertical edges of each panel (end stiles) vary between manufacturers. Some use L-shaped stiles, others use U-channel stiles.
• Hardware markings: Hinges, rollers, and brackets may have manufacturer stamps or part numbers.

Measuring Your Door

If you cannot identify your door visually, precise measurements help narrow down the options. Record these dimensions using the methods from our measuring guide:

• Overall width and height (standard sizes: 8×7, 9×7, 16×7, 16×8, 18×7, 18×8)
• Number of panels (sections stacked vertically, typically 4 or 5)
• Section height (height of each panel)
• Panel thickness (measured at the edge, indicates insulation level)
• Steel gauge (thicker steel = lower gauge number = higher quality)
• Window pattern if applicable (window insert styles are brand-specific; see our window inserts guide)

Other Identification Methods

• Homebuilder records: If your home was built recently, the builder may have records of which door brand and model was installed. In Utah’s builder-grade construction boom (2015-2022), most builders used a limited selection of Clopay, Amarr, or Wayne Dalton models.
• Permit records: Your city’s building department may have permit records that include the door specifications, especially for new construction.
• Previous invoices: Check for any past repair or installation invoices that may list the door brand and model.
• Real estate disclosures: Your home inspection report may have noted the garage door brand and condition.
• Contact the manufacturer: If you know the brand but not the model, the manufacturer may be able to help identify your specific door from photos and measurements.

How to Document and Store Your Specifications

Once you have identified your garage door and opener, create a record you can access quickly when needed. Here is a checklist of everything to document.

Store this information somewhere you can access it quickly, not just on a sticky note in the garage. Good options include a phone note, a home maintenance app, a shared family document, or an email to yourself. Some homeowners keep a small binder in the garage with all home system information, including garage door specs, HVAC info, and appliance manuals.

When This Information Matters Most

Having your model information readily available pays off in several critical situations.

Getting Accurate Repair Quotes

When you call for a repair estimate, the first thing a dispatcher will ask is your door brand and the problem you are experiencing. Knowing your exact model helps the technician determine whether they need to bring specific parts, how long the repair will take, and what the approximate cost will be. Without model information, the technician may need to make an extra trip to get the right parts.

Warranty Claims

Filing a warranty claim requires your model number, serial number, and proof of purchase or installation date. Many warranty claims are denied simply because the homeowner cannot provide these details. Manufacturer warranties on garage doors typically range from 1 year (hardware) to lifetime (certain spring and panel warranties). Your serial number also tells the manufacturer the exact production date and batch, which helps them determine whether your door falls under any recalls or extended warranty programs.

Insurance Claims

After storm damage, a vehicle impact, or other covered events, your insurance company needs your door’s specifications to calculate the replacement or repair cost. The difference between a basic 25-gauge uninsulated door and a premium 24-gauge polyurethane-insulated door can be thousands of dollars. Having your exact model documented ensures your claim reflects the actual value of what was damaged.

Home Sales and Inspections

During a home inspection, buyers and inspectors evaluate the garage door system. Having organized documentation of your door’s brand, model, age, and maintenance history adds value and demonstrates responsible homeownership. It also helps buyers understand what they are getting and can support a higher valuation of the home’s curb appeal investment.

Ordering Replacement Parts

Ordering the wrong remote, keypad, spring, or panel wastes time and money. Each opener brand uses a specific frequency and coding protocol. A LiftMaster 893LM remote will not work with a Genie opener. A Clopay replacement panel will not fit an Amarr door. Your model number is the key to getting the right part the first time. This is especially important for Craftsman openers where parts availability has become limited since the Sears bankruptcy.

Utah-Specific Considerations

Utah’s climate and housing market create some unique challenges for garage door identification that homeowners in milder climates do not face.

Label Degradation by Region

Utah’s varied climate zones affect how quickly identification labels deteriorate:

• Wasatch Front (Salt Lake City, Ogden, Provo): Road salt and UDOT brine spray corrode metal labels and cause adhesive-backed stickers to peel. Doors near major highways (I-15, I-215, I-80) are especially vulnerable.
• Great Salt Lake corridor (West Valley, Tooele, Magna): Salt aerosols from the Great Salt Lake can corrode labels even faster than road salt. Metal identification plates may develop corrosion that makes them unreadable.
• Southern Utah (St. George, Cedar City): Intense UV exposure bleaches printed labels within a few years. The adhesive on sticker-style labels fails in extreme heat, causing labels to fall off entirely.
• Mountain communities (Park City, Heber City, Logan): Temperature cycling between extreme cold and warm days causes expansion and contraction that can crack and peel labels. Condensation can also damage labels over time.

Builder-Grade Door Identification

Utah’s housing boom from 2015 to 2022 produced tens of thousands of homes with builder-grade garage doors. These doors are typically basic models from Clopay, Amarr, or Wayne Dalton that builders purchase in bulk for the lowest cost. The challenge is that builder-grade doors often look identical across different developments, making visual identification difficult without a label.

If you have a builder-grade door in a Utah subdivision, check with your HOA or homebuilder for the original door specifications. Many Utah builders keep records of their standard garage door specifications by subdivision and build year. This information is especially useful if you need to match a replacement panel to your existing door’s color and profile.

Martin Door: Utah’s Local Manufacturer

Martin Door has been manufacturing garage doors in Salt Lake City since 1936, making them one of the few locally-produced door brands available to Utah homeowners. If you have a Martin Door, you have a direct advantage when it comes to identification and parts availability. Their Salt Lake City facility can often look up your door by serial number and provide exact specifications, replacement panels, and parts faster than national brands. Learn more about all the major garage door brands and what makes each unique.

Common Mistakes When Identifying Your Garage Door

Avoid these errors that homeowners commonly make when trying to identify their garage door and opener:

1. Confusing door brand with opener brand. Your garage door and your garage door opener are almost always different brands made by different manufacturers. A Clopay door can have a LiftMaster opener. An Amarr door can have a Genie opener. Record both separately.
2. Assuming all doors in your neighborhood are the same. Builders sometimes switch suppliers between phases of a development. Your neighbor’s door may look the same but be a different brand, model, or even color code.
3. Recording the model number of the remote instead of the opener. Your remote’s model number (like LiftMaster 893LM) is NOT your opener’s model number. The remote model tells you the remote. The opener’s model is on the motor unit on your ceiling.
4. Using the wrong spring specifications. Springs must match your specific door’s weight and size. Even if two doors look the same, differences in insulation, steel gauge, or window inserts change the weight, which changes the spring requirements.
5. Ignoring the serial number. The model number tells you WHAT you have. The serial number tells you WHEN it was made. Both are important for warranty claims, parts ordering, and determining whether your door is under any manufacturer recalls.
6. Not documenting before a remodel. If you plan to paint your door, add insulation, or make modifications, photograph all labels first. Painting over a label makes it permanently unreadable.
7. Assuming online part lookups are always accurate. Third-party parts websites sometimes list incorrect compatibility information. When in doubt, call the manufacturer directly or have a professional verify the correct part number.

Frequently Asked Questions

Where is the model number on a garage door?

The model number is on a label or sticker on the inside of your garage door, typically on the top panel or bottom panel. Stand inside the garage with the door closed and look for a white, silver, or yellow label with printed text. If you do not see it on the panels, check the vertical edges between panels and the inside of the end stiles.

How do I find out what brand my garage door is?

Check the identification label on the inside of the door for the manufacturer name. If there is no label, look for a logo on the exterior hardware, distinctive panel profiles, or branded hinges. A professional technician can identify most brands by visual inspection of the panel profile, end stile design, and hardware style.

Where is the model number on a LiftMaster garage door opener?

The model number on a LiftMaster opener is on a label on the side or back of the motor housing unit mounted to your ceiling. You will need a stepladder to read it. The label shows the model number, serial number, manufacturing date, and horsepower rating. Also note the Learn button color (purple, yellow, orange, or green) as this identifies the programming protocol.

How can I tell what size garage door I have?

Measure the width and height of the door opening from inside the garage. Standard residential sizes are 8×7, 9×7, 16×7, and 16×8 (width x height in feet). For precise measurements, use the methods in our complete measuring guide. Single-car doors are typically 8 or 9 feet wide, and double-car doors are usually 16 or 18 feet wide.

What do I do if my garage door label is missing?

If your label is missing, you can identify your door through panel profile analysis, hardware inspection, and measurements. Check for builder records, original purchase documents, home inspection reports, or HOA records. A professional technician can usually identify the brand and model through visual inspection. You can also contact manufacturers with photos and measurements for identification help.

Is my garage door opener model number the same as my remote model number?

No. Your opener model number (on the motor unit on your ceiling) and your remote model number (printed on the back of the remote) are completely different numbers. The opener model identifies the motor unit. The remote model identifies the handheld device. You need the opener model number to determine which remotes, keypads, and parts are compatible with your system.

How do I find my garage door spring size?

First, identify whether you have torsion or extension springs. For torsion springs, the three key measurements are wire diameter, inside diameter, and overall length. For extension springs, look for a color-coded paint mark on the end that indicates the weight rating. Never attempt to measure springs while they are under tension. A professional can safely identify your exact spring specifications during a service call.

Can a technician identify my garage door if all labels are gone?

Yes. Experienced technicians can identify most garage door brands and models through visual inspection of the panel profile shape, section height, end stile design, hinge pattern, and construction details. At Advanced Door, our technicians work with every major brand daily and can typically identify your door, recommend the right parts, and complete repairs in a single visit.
