20E
Samsung Refrigerator
Severity: ModerateWhat Does This Error Mean?
The 20E error on a Samsung refrigerator signals a fault with the ice maker room temperature sensor. This sensor monitors the temperature inside the ice maker compartment. If it fails or reads an out-of-range temperature, the ice maker stops working and the error appears.
Affected Models
- RF23M8070SR
- RF28R7351SR
- RF27T5241SR
- RF28K9380SG
- Samsung French door models with ice maker
Common Causes
- Ice maker room sensor (thermistor) has failed and is sending incorrect readings
- Wiring harness to the sensor has come loose or corroded
- Ice buildup around the sensor probe causing it to read incorrectly
- Ice maker compartment door not sealing, causing temperature fluctuations
- Control board fault causing misreading of the sensor signal
How to Fix It
-
Unplug the refrigerator and remove all ice from the ice maker bin.
You need to inspect and defrost the ice maker compartment area.
-
Leave the freezer door open for 24 hours to fully defrost the ice maker area.
Any ice coating the temperature sensor probe will melt. This alone can fix the 20E error if ice buildup was the cause.
-
Inspect the small sensor probe inside the ice maker compartment.
It is usually a small black or white cylindrical probe. Check that its wiring connector is fully seated.
-
Check the ice maker compartment door flap or seal.
Many Samsung French door models have a small door that opens when ice is dispensed. Make sure it closes fully and seals tightly.
-
Plug in, allow temperatures to stabilize for 2 hours, then check if the error clears.
If 20E comes back, the sensor thermistor is defective and needs professional replacement.
When to Call a Professional
If defrosting and resetting do not resolve the error, the sensor needs testing with a multimeter. A faulty thermistor requires replacement, which involves accessing the ice maker compartment. Expect repair costs of $100–$200 for parts and labor.
Frequently Asked Questions
Does the 20E error mean my ice maker is broken?
Not necessarily — it means the temperature sensor for the ice maker room is reporting a fault. This could be a temporary issue from ice buildup around the probe. A full defrost often fixes it without any parts replacement.
How is 20E different from 8E on a Samsung refrigerator?
Both relate to ice maker temperature sensing. 8E typically refers to the main ice maker sensor. 20E refers specifically to the ice maker room or compartment temperature sensor. The fixes are similar — start with a manual defrost.
Will my Samsung fridge keep food cold if it shows 20E?
Yes — the 20E error only affects the ice maker compartment sensor. The main fridge and freezer sections continue to cool normally. You may lose ice production, but food storage is not affected.
