Effective 10 November 2026.
The Garage Door Owner gives general information only. It is not professional advice, and it is not a substitute for a trained door technician who has seen your door.
After a loud bang, or if a cable is loose or hanging, or the door is crooked or off its track: don’t run the door, don’t pull the emergency release while the door is open, keep people, children and cars clear, and call a trained door technician. The federal warning in every opener manual says “Weak or broken springs may allow the door to fall rapidly, causing injury or death” (16 CFR 1211.16(b)(2)).
General information only
Everything on The Garage Door Owner (thegaragedoorowner.com) is general information, published to help readers understand the residential garage doors and openers found in US homes. It is not professional advice, and it does not take your door, your springs, your opener, your garage or your local rules into account. Your door’s maker, your opener manual and a trained door technician decide what’s safe for your door, and local codes decide what needs a permit.
Not a door company, installer, maker or parts seller
The Garage Door Owner is not a door company, an installer, a technician, a door or opener maker, a parts seller or a retailer. It does not install, repair, service or inspect doors or openers, sell parts or products, or refer anyone to a door company or technician. We never diagnose a reader’s door, read an opener code for a reader or review a quote, by email or any other way.
No view on your door
Nothing on this site says that your door or opener is safe, what is wrong with it, that it is fine to keep using, that a repair is within your skills, which spring or part your door needs, that an installation meets your local code, or whether you should repair or replace anything. Those are decisions for you, with a trained door technician who has seen the door, and some are decided by your building department.
Steps and your own risk
Garage door springs hold the weight of the door, and a door can weigh from 90 pounds to over 500 pounds (DASMA TDS-176). Springs, cables, drums, bottom brackets and the parts fastened to them are under tension, and a moving door or an opener can crush or trap a person, including a child. Where a page describes a step, it is a step the federal rule, the CPSC or a maker gives owners, and the page names the document it comes from. The federal warning in every opener manual tells owners to “Have a qualified service person make repairs to cables, spring assemblies and other hardware” (16 CFR 1211.16(b)(2)), and the makers whose manuals we have read say the same. This site gives no steps for working on springs, cables, drums, bottom brackets or bottom rollers, and none for bypassing a safety sensor. If a step in your own manual differs from a page here, your manual for your model decides. If you are not sure, or the door is heavy, crooked, noisy in a new way or fails the reverse test, stop and call a trained door technician. You are responsible for any work you choose to do.
Makers and models differ
Where a page describes what a maker says, it names the document it read, by model or part number and print date. Your door or opener may be a different model, a different year or come with a different edition of the manual, and what one maker says is not a rule for another. Opener lights and codes in particular change between models and years: the label on your opener and the manual for your model decide what they mean. Where we have not read a maker’s document, the page says “not confirmed”.
Local codes, permits and licensing
Building codes are adopted by states and local governments, often with their own changes. Where a page cites the International Residential Code, it is citing the model code in a named edition, not the law where you live. Whether a new door, an opener, a wind-rated door or other work needs a permit, an inspection or a licensed contractor is set by your state and local government. Your building department decides. Some states also set rules for people who sell, install or service openers, and pages describe those only from the statute’s official text. The federal opener rule (16 CFR 1211) governs how openers are made, not what an owner must do with an older one.
Rules and figures change
The federal opener rule is amended from time to time. The latest change, published on 30 October 2026, is scheduled to take effect on 29 December 2026 unless the CPSC receives significant adverse comments by 30 November 2026 (91 FR 68456, checked 10 November 2026). Makers revise their manuals, code tables and control boards. DASMA revises its technical data sheets. Model codes are published in new editions and adopted on different dates in different places. A rule is right only for the products and period it applies to. Each rule and figure on this site shows its source and the day we read it, and it may have changed since. Check the current rule with the original source before you rely on it.
Tools show records and estimates, not decisions
Our tools do arithmetic on what you enter and show the maker documents, DASMA sheets, rules and assumptions they name. Their results are records and estimates. The opener code lookup gives a maker’s meaning for a light or code as printed in the document named; it is not a diagnosis of your opener. The spring tool makes a record to hand to a technician; it never sizes or picks a spring, and DASMA’s colour codes are only a partial way to identify one. The spring life tool’s years are our arithmetic on a cycle rating and your use, not a prediction. The size checker shows one maker’s published clearances; your door’s installation manual decides. Defaults that are our assumption are labelled, and you can change them.
Recalls
Where a page mentions a recall, it names the CPSC recall number and date. Whether your product is affected depends on the model and dates in the recall notice. Check the CPSC’s recall pages and the maker’s own notice, and follow what they say.
Accuracy
Pages are checked against the sources they cite, but no check catches everything. Check important details with the original source before you rely on them. See also our terms of use.
How our content is made
Every page is fact-checked against its sources before it is published. Pages appear under The Garage Door Owner name. Our editorial policy and how we check page explain the process.
Advertising and independence
The Garage Door Owner is free to read and funded by display advertising. Advertisers have no say over what we publish, and an ad on a page, including an ad for a door company, a door or opener maker or a parts seller, is not an endorsement or a referral. We use no affiliate links, accept no paid placements, sell no leads, make no repair referrals and publish no product rankings. Names of makers, brands, standards bodies and other organizations are used only to identify them, and we are not affiliated with them.
External links
We link to regulations, statutes, makers’ documents, agencies and other websites so you can check what we say. We do not control those sites and are not responsible for their content.
Questions and corrections
If you think something is wrong, email contact@thegaragedoorowner.com with the page address and a source, and we will look at it. We can’t diagnose a door, read opener codes for a reader or recommend door companies, technicians or products. See also our corrections page.
