This page explains where the information in our guides comes from, how we check it, and what we do when we get something wrong.
Who Writes the Guides
Our guides are researched and written by the My Garage Blog editorial team. We are not licensed garage door technicians and we don’t present ourselves as having repaired the openers we write about. Our job is research: finding the official answer, checking it, and explaining it clearly.
Sources We Use
- Manufacturer documentation first. Owner’s manuals, installation guides and official support pages from Chamberlain Group (LiftMaster, Chamberlain, Craftsman), The Genie Company, Marantec, Ryobi and other makers. Code meanings, button locations and programming steps come from these.
- Official videos. Where a manufacturer has published a how-to video, we embed it so you can watch the real procedure.
- Codes and standards. For electrical and safety questions we refer to the National Electrical Code and the federal safety rules for garage door openers, and we tell you to follow local code and your manual.
- Other sources, with care. Dealer instructions, technician forums and retailer listings can fill gaps, but we label them for what they are and don’t treat them as official.
How We Check a Guide
- Every specific claim (an error code, a model number, a frequency, a weight, a step) is matched to a source, and the source is linked in the guide.
- If two official sources disagree, we say so instead of picking one silently.
- If we can’t verify a claim, we remove it or clearly mark it as unverified.
- Guides that have been checked this way show a Last verified date and the sources used.
Images
Some images on this site are illustrations created to explain a part or a step; they are not photos of a specific product. Real-world photos come from Creative Commons licensed sources and are credited in the caption with a link to the original and its license.
Product Comparisons
Our “best” product guides compare products using manufacturer specifications, compatibility information and published documentation. We don’t run hands-on tests, and we don’t describe products as tested. Prices and availability change often, so check the current listing before you buy.
Safety
We follow the manufacturers’ safety warnings. That means we never give instructions for adjusting torsion springs, cables or drums, and we point out when a manufacturer says a job is for a trained technician. Your opener’s own manual always takes priority over any guide here.
Corrections
When we find or are told about an error, we check it against the manufacturer’s documentation, fix the guide and update its Last verified date. You can report a problem through our contact page.
