Samsung Refrigerator Error Code 15E — What It Means & How to Fix It

What Does This Error Mean?

Error code 15E on a Samsung refrigerator means there is a fault with the ice maker temperature sensor. The sensor monitors the temperature inside the ice maker to control the freezing and harvesting cycle. When the refrigerator cannot get a proper reading from this sensor, it sets the 15E code. Your fridge will likely stop making ice, but the rest of the refrigerator and freezer should still cool normally. This is a relatively minor fault that often resolves with a reset or sensor replacement.

Affected Models

Samsung French Door Refrigerators
Samsung Side-by-Side Refrigerators
Samsung RF series models
Samsung RS series models

Common Causes

A failed or open-circuit ice maker temperature sensor (thermistor)
A loose or disconnected wire harness to the ice maker sensor
Ice buildup around the sensor preventing accurate temperature readings
A cracked or damaged sensor from physical contact during cleaning
A faulty main control board not reading the sensor correctly

How to Fix It

Start with a hard reset. Unplug the refrigerator from the wall outlet and wait 5 minutes. Plug it back in and allow it to restart fully. If the 15E code was triggered by a temporary sensor glitch, the reset will clear it.

Always try a reset before replacing any parts — it resolves roughly 20-30% of error codes.
Check the ice maker for ice buildup. Excessive frost around the ice maker bin or sensor area can interfere with sensor readings. Remove the ice bin and look for thick frost or ice sheets. If you see heavy buildup, initiate a manual defrost cycle.

To force defrost on most Samsung refrigerators, press and hold the top two buttons on the control panel simultaneously for 8 seconds until 'Fd' appears.
Inspect the wire harness connecting the ice maker sensor to the main harness. Pull the ice maker assembly out slightly and check the connector. Look for any pins that have backed out, corrosion, or a connector that is not fully seated.

A loose connector is a very common cause of sensor error codes on Samsung refrigerators.
Test the ice maker temperature sensor with a multimeter. The sensor is a thermistor — its resistance changes with temperature. At room temperature (70°F / 21°C), it should read approximately 5,000-10,000 ohms. An open reading (infinity) means the sensor is failed.

Replacement sensors for Samsung ice makers are available online for $15-$40.
If the sensor and wiring are fine, the main control board may have a fault affecting how it reads the sensor signal. Board replacement is an expensive last resort — confirm the sensor is good before pursuing this.

A Samsung-authorized technician can test the control board output before recommending replacement.

When to Call a Professional

If you have performed a reset and defrost cycle and the 15E code keeps coming back, the sensor itself likely needs replacement. Samsung sensors are inexpensive parts ($15-$40) but require removing the ice maker assembly to access. If you are not comfortable with that disassembly, a Samsung-authorized technician can replace the sensor. Expect $100-$200 for a service call including parts.

Frequently Asked Questions

Will 15E make my refrigerator stop cooling?

No — 15E only affects the ice maker. The main refrigerator and freezer compartments should continue to cool normally. You will just not get any new ice until the fault is resolved. You can still use the freezer normally and manually add ice from bags if needed.

Is 15E covered under Samsung's warranty?

If your refrigerator is under Samsung's standard 1-year parts and labor warranty, sensor repairs are covered. Samsung also offers extended warranties on the sealed system (compressor, evaporator) for up to 5 years, but that does not typically cover sensors. Check your purchase date and register your appliance on Samsung's website to confirm warranty status.

How much does a Samsung ice maker sensor replacement cost?

The sensor itself is typically $15-$40 online. If you hire a technician for the replacement, expect a total bill of $100-$200 including the service call fee. It is a relatively straightforward repair that takes 30-60 minutes for an experienced technician.
