Samsung Refrigerator Error Code 40 E — What It Means & How to Fix It

What Does This Error Mean?

The 40 E error means your Samsung refrigerator's ice maker fan has a fault. The fan that circulates cold air in the ice maker compartment is not working. Ice production will stop and the freezer may warm up.

Affected Models

RF28R6201SR
RF23M8070SR
RS27T5200SR
Most Samsung French door and side-by-side refrigerators with ice makers

Common Causes

Ice maker fan motor has failed
Ice has built up around the fan blades preventing rotation
Fan blade physically blocked by a food item or ice chunk
Wiring connector to the fan motor has come loose
Control board fault not sending power to the fan

How to Fix It

Check the ice maker compartment for visible ice buildup around the fan.

Ice around the fan is the most common cause of this error.
Turn off the refrigerator and let the ice maker area defrost naturally.

Place towels inside to absorb meltwater. This may take 4–8 hours.
Alternatively, use a hair dryer on low heat to gently melt ice near the fan.

Keep the dryer moving — do not hold it in one spot for too long.
Once defrosted, restore power and check if the fan runs.

You should hear a quiet hum from the fan after the fridge powers back up.
If the 40 E error returns, the fan motor needs professional replacement.

A technician can test the motor and replace it if needed.

When to Call a Professional

If defrosting doesn't resolve the issue — the fan motor likely needs replacement. Fan motor replacement costs $120–$280 including parts and labor. Contact Samsung support or a certified appliance technician. Avoid storing expensive food until the issue is resolved.

Frequently Asked Questions

Will my Samsung refrigerator still cool food with the 40 E error?

The main fridge compartment may continue cooling. But the ice maker area will warm up. Move perishables to the main fridge section and fix the error promptly.

How did ice build up around my Samsung refrigerator fan?

If the door seal leaks, warm humid air gets in and freezes on the fan. A defrost system failure can also allow excessive ice buildup. After fixing the fan, check the door seals and defrost system too.

How much does it cost to fix the Samsung refrigerator 40 E error?

If it's ice buildup, manual defrosting is free. If the fan motor needs replacing, expect $120–$280 including labor. Always confirm the diagnosis before ordering parts.
