What Does Error Code 24E Mean on a Samsung Refrigerator?

Evaporator sensor error — freezer temperature sensor fault.

The 24E code (also shown as 24C) fires when the control board reads an out-of-range signal from the freezer evaporator NTC thermistor clipped to the coils. Because the board relies on this sensor to time defrost heater cycles, an open, shorted, or drifting reading trips the fault. It differs from 25E, which points to the defrost heater or thermal cutoff circuit itself; 24E is specifically the sensor input feeding that logic.

Models affected: Samsung refrigerators using the numeric fault-code system, including French-door and side-by-side models such as RF28R7351SG, RF263BEAESR, RF23M8070SR, RS27T5200SR and RF27T5201SR
What owners report: Owners commonly report this code surfacing alongside frost buildup on the back freezer panel or a warming freezer, and sometimes after a power blip. A loose or corroded connector behind the rear panel is a frequent false trigger, and many find reseating that plug clears it before any part swap is needed.

What Causes Error Code 24E?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Failed NTC temperature sensor (thermistor) 65% of cases
  2. 2
    Sensor connector loose or corroded 25% of cases
  3. 3
    Wiring harness short to ground 10% of cases

How to Fix Samsung Refrigerator Error Code 24E

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Locate the evaporator sensor

    The evaporator sensor is clipped to the evaporator coils behind the back panel in the freezer compartment.

  2. 2

    Test the sensor resistance

    At 32°F/0°C, a healthy Samsung thermistor reads approximately 16.3k ohms. Test and compare to spec.

    🔩 Multimeter
  3. 3

    Check and reseat connector

    The connector often vibrates loose over time. Unplug and firmly reseat.

  4. 4

    Replace the sensor

    The thermistor clips onto the evaporator coil. Unclip the old one, clip in the new one, reconnect.

How to Reset Error Code 24E

After replacement, unplug for 5 minutes and plug back in. Run a manual defrost cycle by holding 'Freezer Temp' and 'Lighting' for 8 seconds.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

If the sensor is new and correct but errors continue, the main PCB sensor input circuit may have failed.

Average professional repair cost for this issue: $150–$300

Frequently Asked Questions

Can I keep using my Samsung Refrigerator when error 24E appears? +
You often can for a cycle or two, but the sensor issue behind 24E will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes 24E on a Samsung Refrigerator? +
Across reported Samsung refrigerator repairs, the most frequent is failed NTC temperature sensor (thermistor) (65% of cases), sensor connector loose or corroded (25%), then wiring harness short to ground (10%). Check them in that order before replacing any parts.
24E keeps coming back after a reset — what should I check next? +
A reset only clears the stored 24E fault; if it returns, the sensor problem is still present. Move on to the physical checks — locate the evaporator sensor, then test the sensor resistance — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Samsung Refrigerator error 24E? +
A DIY repair typically runs $15–$40 in parts, versus $150–$300 for a professional service call, so handling it yourself saves around $135. Expect the work to take roughly 30–60 minutes.
Which Samsung Refrigerator models show error 24E? +
24E is documented on Samsung refrigerators using the numeric fault-code system, including French-door and side-by-side models such as RF28R7351SG, RF263BEAESR, RF23M8070SR, RS27T5200SR and RF27T5201SR. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
