Error codes
Refrigerator error codes
A code narrows the search, and it is also the thing most often read wrong. The same characters mean different things on different brands and sometimes on different generations of one brand, and a fair number of the codes people search for are not faults at all — they are modes the appliance was left in.
Start here: a code is a lead, not a verdict
Before you look yours up, three things decide whether the answer will be any use. Write down the exact characters, including every letter and the order they appear in. Find the full model number, because without it a code is a guess. And note whether the appliance is still cooling while the code shows, because that single answer decides whether this waits for a scheduled visit.
Photograph the display rather than transcribing it, and do it before you reset anything. Some codes clear on a power cycle and take the only piece of evidence with them.
Mode, not a fault
The most useful group on this page. Nothing has failed, no part is needed, and the appliance is doing what it was told.

Mockup note on scope. R5. A code goes on this site only when it has proven demand AND a source. A search phrase proves that somebody looks for a code, not that the code exists — a sister site once published ~38 invented codes that were really symptoms. Entries below carry `confidence`. Only `documented` may go live; `pending` renders a visible flag in the mockup and must be filled from the brand research pass before publishing. 🔴 Nothing here may be carried over from *repairguide.com: sentence overlap with that corpus must be zero.
Not a refrigerator? Each of these is its own appliance, and has a site of its own.
