How do I find manuals online?

Last reviewed: September 23, 2026 · Markdown version

Start with the model number, not the product name, and start at the manufacturer's own support site. That is our advice rather than anyone's rule, and the rest of this page is the reasoning behind it.

Get the model number first

A product name can cover several versions of a thing; a model number is meant to identify one. Look for it on the rating label on the product itself, or in the settings screen of anything that has one, and copy any suffix exactly.

Then search "MODEL-NUMBER" manual pdf, with the quotation marks, so the search engine looks for that exact string.

Where to look, in order

The manufacturer's support site. If it publishes the manual, that copy is the authoritative one.
The retailer's product page. Some listings attach the manual as a PDF; worth a look when the manufacturer's page has gone.
The regulator, for radio equipment — the FCC's search page says an FCC ID "is assigned to all devices subject to certification" and that its advanced search helps "find the information on a grant of certification" (FCC ID Search, read 23 September 2026). Whether a filing includes the manual is not something that page says.
Third-party manual sites. Check the model number on the first page before trusting the content, and be wary of anything that asks you to install something to get the file.

Discontinued products

When a support page has gone, two things are worth trying. A manufacturer's site for another country may still carry the file. And the Wayback Machine may hold an archived copy of the old page. The Internet Archive says you can tell whether a link is archived "by entering the image or link's URL into the Wayback Machine search box", and that you can see every capture of one address "by replacing the date code with an asterisk (*), ie: http://web.archive.org/*/www.yoursite.com" (Using the Wayback Machine, read 23 September 2026). Its page does not promise any particular file was captured.

Enthusiast forums for the product category are another place to ask, particularly if you need a service manual for a repair rather than the user manual.

The part nobody plans for

A household accumulates manuals the way it accumulates appliances: a boiler, a dishwasher, a router, a car, a drill, a thermostat. Thirty or forty PDFs, downloaded years apart, named manual.pdf, UserGuide_EN.pdf and om_2019.pdf. When the dishwasher shows an error code, you do not want a list of file names — you want the two pages that mention that code, and you do not remember which appliance's manual they are in.

Error codes are the clearest case: the code is printed inside the manual and appears in no file name. Searching across a pile.
