Most garage doors don’t wear their identity on their sleeve. If your garage door needs a repair or replacement part, one of the first questions any technician will ask is: “What’s the model number?” If you don’t have that information ready, you could end up ordering the wrong part, wasting time, and delaying service. Knowing exactly how to find your garage door type model number will save you frustration and help speed up the repair or replacement process.
The model number of your garage door tells you the make, style, material, insulation type, and sometimes even the color. This number helps technicians match parts correctly and make recommendations that fit your exact door. Not every hinge, panel, or spring works with every model. If you guess, you’re likely to get it wrong.
If your garage door was installed by a professional, the installer might have left behind a user manual or installation packet. This packet often contains a sticker or printout with your door’s model number and specifications. If you can’t find the manual, don’t worry. There are still several ways to identify your garage door model number directly from the door itself.
Most garage doors have a sticker placed on the inside of the top panel. Stand inside your garage with the door closed and check the top left, top right, or center of the panel closest to the ceiling. Use a flashlight if needed.
The label might include:
This label is usually placed where it’s protected from weather and visible during regular inspections. Once you find it, write down the entire string of numbers and letters. Some model numbers look similar, and small differences matter.
Some manufacturers, like Clopay, place model and serial numbers on the vertical track near the bottom. Look for a label or sticker facing toward the inside of the garage, near the roller bracket or safety tag. If you spot it, take a photo. These labels can fade over time, especially in garages with a lot of sunlight or moisture.
If the label has worn off or was never installed, you can still get a good idea of your garage door type and model number by gathering a few key details.
Count the number of panels or sections in the door and note the pattern. Is it short panel, long panel, or flush? Does it have windows? If so, where are they located? Some models are only available in certain panel layouts or window designs.
Write down the exact width and height of the door. This helps narrow down the product line and will be important when checking manufacturer catalogs or contacting a service company.
Is your door steel, aluminum, or wood? Knock on it to check thickness. Some steel doors are hollow, while others are insulated with polystyrene or polyurethane foam. Look at the side of the door for clues. Insulated doors often have a sandwich-style panel with a sealed edge. Knowing these details won’t give you the exact model, but they will help a technician narrow it down and cross-check manufacturer specs.
If your garage door has a brand name visible (like Haas, Clopay, Wayne Dalton, or CHI), visit their website and check for product identification tools. Many manufacturers offer support pages where you can enter part of a serial number or browse by door style.
Still not sure? Take a clear photo of the door from the outside and inside, then email it to customer support. Be sure to include measurements and any other details you’ve gathered. Most support teams can help you track down the correct model.
Model numbers and serial numbers are not the same thing. A model number tells you the product line and style. A serial number is unique to your door and may include manufacturing date and batch information. Both can be helpful, but the model number is what you need when ordering parts or requesting service. If the only thing you can find is the serial number, try searching that number online with the manufacturer’s name. Some serial numbers decode directly to the model number.

Garage doors rely on small details to work safely. One of the most important parts of the system sits just a few inches above the floor: the garage door sensors. When these sensors aren’t aligned correctly, the door may not close, may reverse mid-close, or might stop altogether. Learning how to align garage door sensors can save time, prevent unnecessary repairs, and keep your garage door operating safely.
Garage door sensors prevent the door from closing on a person, pet, or object. They use a beam of infrared light to detect anything in the door’s path. If something breaks the beam, the system tells the garage door opener to stop or reverse. The sensors work in pairs. One sensor sends the beam, and the other receives it. If that signal gets interrupted or if the sensors fall out of alignment, the garage door won't function properly.
Garage door sensors sit on each side of the door, about 4 to 6 inches above the ground. They’re mounted on the vertical track or bracket that supports the door’s rollers. Each sensor has a small lens and indicator light. One light stays green to show the receiving sensor is powered and aligned. The other usually glows orange or yellow to confirm the sending sensor is functioning. If either light is blinking or off, that’s a red flag.
A misaligned sensor pair is one of the most common reasons garage doors won’t close. If you notice any of these signs, the sensors likely need adjustment:
If the door closes only when you hold the wall button, the sensors are trying to prevent what they think is an unsafe close. They need to be realigned.
Sensors don’t shift on their own unless something bumps them or something interferes with the brackets. Here are the most common causes:
Checking these problems before calling for a repair can help you get your door working faster.
Knowing how to align garage door sensors starts with a simple check and adjustment process. All you will need is a screwdriver, some string, and a little patience.
Inspect both sensor lenses. Wipe away dust or debris with a clean cloth. Check the wires for damage and make sure they are securely connected.
Look for any signs of bent brackets or loose screws. Tighten everything down so the sensors sit snugly in their mounts. You should be able to gently adjust them side to side without force.
Tie a piece of string from one sensor to the other. Stretch it tight so it runs across both sensor lenses. Use a level to check the string. Adjust the sensors up or down so they’re perfectly in line with the string and each other. Once aligned, the sensor lights should turn solid, showing the signal is connected.
Press the remote or wall button. If the sensors are aligned correctly, the door should close smoothly without stopping or reversing. If the lights continue blinking or the door still won’t close, double-check the alignment and clean the lenses again. Sometimes, it takes a few small tweaks to get it just right.
Garage door sensors aren’t just a safety feature. They’re required by law on all automatic garage doors built since 1993. If they aren’t working correctly, the door poses a serious hazard. Learning how to align garage door sensors gives you control over a common problem that doesn’t always need professional service. But if you’ve tried aligning them and the lights still won’t stay solid, the issue might be deeper. Bad wiring, damaged sensor units, or a faulty garage door opener can also cause problems.
Garage doors work best when every part is in sync, and sensors are no exception. If you’ve gone through the steps and your sensors still aren’t working right, it may be time to call in some extra help.

Garage doors don’t just go up and down—they need to move smoothly, stop where they should, and close fully without slamming. If your garage door opens too far or doesn’t close all the way, it can create problems ranging from security issues to damage on the door itself. So, how do you adjust the height of a garage door? Learning how to do this can help you fix small issues, but it’s not always a job to take lightly. There’s tension, hardware, and electrical components involved, so you’ll want to approach this carefully. Let’s break down how height adjustments work and how to know when it’s time to bring in a professional.
Garage doors use one of two systems: torsion spring or extension spring. Torsion spring systems sit above the door and twist to lift it. Extension springs run along the sides and stretch to provide lift. The type of system matters because each one uses different methods to control how far the door travels.
If you’re adjusting the height to fix an issue like a gap at the bottom, a door that opens too high, or one that stops too soon, you’ll need to check both the opener settings and the door’s hardware. Don’t make changes until you understand which part needs adjusting.
How do you adjust the height of a garage door? If your door is powered by an automatic opener, you’ll find that most modern systems have limit screws or dials that control how far the door travels when opening or closing. These controls are often located on the back or side of the motor housing.
Keep an eye on the door's movement. If it starts opening too fast, slamming down, or acting strange, stop right away. You could be putting extra strain on the motor or door. At this point if you start to feel unsure about what step to take next, don't hesitate to call a professional.
You might think the springs are the next thing to tweak if the opener settings don’t fix the issue. But this is where things get risky. Torsion springs hold a huge amount of tension, and adjusting them without the right tools or training can lead to serious injury.
How do you adjust the height of a garage door with spring tension? If you’re asking that, and you don’t already have winding bars and safety gear, it’s probably not something you want to take on yourself. Spring tension directly affects the balance of the door, which in turn affects how high it opens and how well it closes. Trying to adjust springs with makeshift tools or without knowing the tension level can easily lead to damage, or worse, injury.
Sometimes, the issue isn’t the opener or springs. If your garage door isn’t reaching the ground or is stopping too early, it might be binding in the tracks or catching on worn-out cables. Rollers that are misaligned or tracks that have shifted can block the door from reaching its full height.
Some garage doors also have mechanical stop bolts that physically limit how far the door can travel. These are usually found on commercial doors or older models. If one of these is loose or has moved, it could stop your door short or let it go too high.
You might be able to handle opener adjustments with a screwdriver, but anything involving springs, tracks, or cables should be left to a professional. Misjudging even one part of the adjustment can lead to more damage or serious safety issues. Technicians with the right training and equipment can diagnose the issue and fix it without putting your home or safety at risk.
