Step-by-Step DIY Fix Guide
- SAFETY: Unplug the refrigerator before accessing the ice maker compartment.
- Check that the ice maker flap or door is fully closed and seated correctly.
- Inspect the ice maker compartment fan (usually visible through the ice chute or by removing the ice bucket) for visible ice build-up.
- If ice is present: unplug the refrigerator and allow the ice maker compartment to defrost naturally for 12–24 hours with the ice maker door open. Place towels to absorb meltwater.
- After defrost, reseat the ice bucket and plug back in.
- If 40E returns after defrost, the fan motor has failed and needs professional replacement.
If the warning comes back after restart
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
What This Error Means
Error 40E on your Samsung refrigerator means: The fan inside the ice maker compartment is not operating. This fan circulates cold air through the ice maker area to maintain freezing temperatures and assists with ice production. Also displayed as 40C on some models. The refrigerator's self-diagnostic system has flagged this condition and may have paused affected functions.
The most frequent cause is ice build-up around the fan blade preventing it from spinning — often caused by leaving the freezer door open. Work through the causes and steps below before calling a technician.
Many cases of 40E can be partially resolved by the homeowner. Complete all DIY steps before contacting a technician.
Fan errors in Samsung refrigerators are most commonly caused by frost build-up freezing the fan blade in place. A door left open — even slightly ajar — can cause enough warm-air infiltration within hours to ice over the fan. Check the door seal before anything else, and budget 24–48 hours for a full manual defrost if frost is the cause.
Most Likely Cause by Symptom
The Samsung refrigerator may stop, pause, or refuse to complete the cycle normally.
Likely cause: Ice build-up around the fan blade preventing it from spinning — often caused by leaving the freezer door open
Check first: SAFETY: Unplug the refrigerator before accessing the ice maker compartment.
The appliance may fail to start because the door or lock state cannot be confirmed.
Likely cause: Ice maker door or flap left open or not seated correctly, allowing warm air infiltration
Check first: Check that the ice maker flap or door is fully closed and seated correctly.
Common Causes
- Ice build-up around the fan blade preventing it from spinning — often caused by leaving the freezer door open
- Ice maker door or flap left open or not seated correctly, allowing warm air infiltration
- Fan motor failure
- Wiring fault between the ice room fan and the control board
What Not to Do
- Do not use a hair dryer or heat gun inside the ice maker compartment to melt ice — heat damage to plastic components is permanent
Model and Display Variation Notes
Model-family notes
- Samsung refrigerator display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
- Some models may display the same fault as 40E, 40C.
Display and panel differences
- Some control panels show this issue as 40E, 40C instead of only 40E.
- Panel wording and whether the code appears with letters, numbers, or a longer variant can differ by model family.

When Not to Keep Troubleshooting
40E returns within a few days of a full defrost
- Fan is visibly ice-free but does not spin when powered
How to Prevent It Recurring
- Do not leave the freezer or ice maker door open — even a few minutes of warm air infiltration causes frost build-up around the ice room fan
- Check that the ice maker flap closes fully every time you remove the ice bucket
Related Error Codes
21E
Samsung refrigerator error 21E usually means the freezer evaporator fan is not spinning normally, so cold air is not circulating through the cabinet as it should.
22E
Samsung refrigerator error 22E usually means the fresh-food compartment fan is not circulating cold air correctly.
39E
The ice maker has failed to complete its harvest cycle within the expected time. The ice maker motor or its control system is not finishing the cycle of making and ejecting ice cubes.
