Samsung Refrigerator 40E / 40C Error
An honest short page, and it says why: Samsung publishes this code's meaning and no procedure. Rather than borrow another code's reset, the page prints Samsung's actual route.
What to check first
- Read the code exactly as displayed: 40E / 40C. Write it down or photograph the display before anything changes it.
- Leave the refrigerator plugged in, and do not press panel buttons to make the code go away — Samsung's standing rule exists so the code survives for diagnosis.
- On Family Hub models, Samsung's Self Check (Apps → Fridge Manager → Fridge Settings → Self Check → Start) lists current or past error codes on screen — use it to confirm the code.
- Request service through Samsung's Support Center, quoting the code and the model number. That is Samsung's published route for this code.
40E / 40C is one of the codes Samsung names at the end of its US refrigerator list — "some of the more commonly received error codes and their meanings" — as Ice Room Fan Error. For these codes Samsung publishes the meaning and nothing else: no causes, no checks, no reset. Its standing instruction covers them instead — for any other code, visit the Support Center to request service. This page follows that exactly.
Safety first
- Samsung's standing rule for its refrigerators (its US and Canadian lists): unless directed, do not unplug the refrigerator, and do not attempt any interaction with the panel to try to make the error code “go away” — doing either of these will make it harder for a technician to diagnose and correct the issue.
- The stop condition below is FixSignal's own general safety precaution, printed on every FixSignal guide; it is not a Samsung instruction. Samsung's guidance for this code is what this page prints from its Samsung sources.
- Stop condition — FixSignal precaution, not a Samsung code-specific instruction: If you notice smoke, a burning smell, damaged electrical parts, or significant water leakage, stop using the refrigerator. Do not touch a damaged plug, cable, or wet electrical area. If it is safe to do so, disconnect power; otherwise, keep clear and seek qualified assistance. Do not resume use until the hazard has been assessed.
What Samsung publishes — and what it does not
The documented meaning
Samsung US's definition for 40E / 40C, in full: Ice Room Fan Error. That sentence is the complete consumer documentation for this code.
No published cause list
Samsung's consumer documentation publishes no causes for 40E / 40C. Wider explanations in circulation come from Samsung's service documentation, which Samsung does not publish for consumers — so they are not printed here as fact, and no cause is guessed from the code's name.
Why the code should be left readable
Samsung's lists open with the reason this page does not offer a reset: unplugging the refrigerator, or interacting with the panel to make a code "go away", makes it harder for a technician to diagnose and correct the issue. A code preserved is a diagnosis half-made.
Step-by-step checks
- Read and record the code exactlyNote the code character by character (40E / 40C), and the refrigerator's model number from its rating label. Samsung's codes repeat across appliances and differ by a single letter between families, so the exact display matters.
- Do not clear it the unofficial wayNo unplugging to reset, no panel combinations: Samsung does not publish a clearing procedure for 40E / 40C, and its standing rule is against improvising one.
- Family Hub models: run Samsung's Self CheckApps → Fridge Manager → Fridge Settings → Self Check → Start. Samsung documents that the list of current or past error codes displays when the check finishes — a clean confirmation of the code to quote.
- Request serviceSamsung's route for any code without a published procedure: visit the Support Center and request service, quoting the code and the model number.
When to call a technician
Samsung publishes no owner troubleshooting for 40E / 40C, so the technician boundary is the whole page: record the code, preserve it, and hand it over. Quote the code, the model number, and what the refrigerator is or is not doing (cooling, making ice, running) when you request service.
Model differences
| What you have | What changes |
|---|---|
| Model scoping | Models with an ice room (a separate ice compartment). Samsung files 40E and 40C as a single entry. |
| 40E vs 40C | Two display forms of one entry — Samsung's US list files them together; there is no separate 40C procedure. |
| Family Hub models | The Self Check list (Apps → Fridge Manager → Fridge Settings → Self Check) is Samsung's documented way to read current or past codes on the Hub screen. |

- Model number noted from the rating label
- Refrigerator left plugged in; code not cleared (Samsung's rule)

Frequently asked questions
What does 40E / 40C mean on a Samsung refrigerator?
Samsung US's definition: Ice Room Fan Error. It publishes no further consumer documentation for this code.
How do I reset or clear 40E / 40C?
Samsung publishes no reset for 40E / 40C — and its standing rule is not to unplug the refrigerator or use the panel to make a code go away, because that makes diagnosis harder. Its route for this code is the Support Center.
How is 40E different from 21E and 22E?
All three are fan codes, but for different fans: 21E is the freezer fan, 22E/22C the fridge fan, and 40E/40C the ice room fan. Unlike 21E and 22E, the ice room fan code has no Samsung-published owner procedure — its route is the Support Center.
