Samsung Refrigerator 14E Error Code: Step-by-Step Fix
Required Tools for this Fix
- Screwdriver
- Replacement ice maker assembly
Quick Summary Answer: The Samsung refrigerator error code 14E indicates an Ice Maker Sensor circuit error, meaning the main control board has lost communication with or detected an abnormal voltage reading from the ice maker’s internal temperature sensor (thermistor). This issue is most commonly caused by frost buildup encasing the sensor, a loose or damaged wire harness, or a failed sensor inside the ice maker mold. The primary fix is to perform a hard reset, thaw any ice blockages in the ice room, inspect the wiring harness, or replace the ice maker assembly.
Warning: Electrical Shock Hazard
Always disconnect the refrigerator from its power source before removing panels, touching wire harnesses, or handling electrical components. Turn off the dedicated circuit breaker or pull the wall plug. Failure to do so can cause severe electrical shock, component damage, or personal injury.
What Is Samsung Refrigerator Error Code 14E?
Error code 14E points directly to an open, shorted, or disconnected ice maker sensor circuit line. On standard digital displays, it renders as “14 E” or “14 C”. On models with twin 88-segment LED displays, the error lights up specific digital segments on the freezer or fridge temperature readouts.
The ice maker thermistor monitors the temperature of the ice tray mold. The main control board (PCB) sends a direct 5-volt DC reference signal to this thermistor. As the tray gets colder, the internal resistance of the sensor changes, altering the voltage sent back to the processor.
When the ice mold reaches approximately 1°F to 9°F (-17°C to -13°C) for a sustained period, the control board initiates a harvest cycle. If the board detects that the resistance is infinite (open circuit) or zero (short circuit), it halts ice maker operation and displays the 14E fault code.

[Ice Maker Thermistor (Sensor)] ---> Fails / Reads Open (14E Triggered)
In the vast majority of modern Samsung French-door and side-by-side models, this thermistor is built directly into the ice maker assembly. You cannot purchase the thermistor as an isolated part. Fixing this sensor circuit generally means inspecting the wiring route or replacing the complete ice maker unit.

Common Symptoms Accompanying Code 14E
When error code 14E triggers, you will likely notice multiple secondary symptoms throughout the appliance. Recognizing these helps confirm that the issue is isolated to the ice maker loop rather than a sealed system failure.
- Complete Cessation of Ice Production: The ice maker will not fill with water, harvest, or cycle.
- Flashing Control Panel: The display screen may blink continuously or flash the digits “14” and “E” alternately.
- Chime or Alert Beeps: The refrigerator may emit an audible chime pattern upon opening or closing the doors.
- Frost Accumulation in the Ice Room: You may see heavy frost, slush, or solid ice pooling around the ice maker housing or inside the auger tray.
- Normal Cooling Elsewhere: The fresh food compartment and lower freezer sections will continue to maintain their programmed temperatures properly.

1. Clear Transient Glitches with a Hard Reset
Samsung control boards can register a false 14E code after an electrical surge, brownout, or sudden flicker in grid power. A transient voltage spike can confuse the analog-to-digital converter on the PCB.
We recommend performing a hard capacitor drain first.
- Disconnect the refrigerator from the wall receptacle or trip the circuit breaker.
- Leave the power completely disconnected for a minimum of 10 full minutes. This duration allows the capacitors on the inverter and main control boards to discharge completely.
- Restore power to the unit.
If the 14E code immediately returns upon reboot, the control board ran its power-on self-test and detected a permanent open or short circuit. If the display stays clear, monitor ice production over the next 24 hours.
2. Address Ice Room Frost and Moisture Intrusion
A massive percentage of Samsung 14E errors stem from physical frost packaging the ice room assembly. Air leaks around the ice room door gasket allow warm, humid room air to infiltrate the sub-freezing ice compartment.
This moisture condenses directly onto the ice tray, motor housing, and sensor leads. Once the moisture freezes into solid ice, it expands, dislodges harness pins, or insulates the thermistor from tracking temperature changes.

How to Force Defrost the Ice Compartment
You can use Samsung’s onboard Forced Defrost (Fd) cycle to melt this frost without disassembling the housing:
- Simultaneously press and hold Energy Saver and Fridge (or Power Freeze and Lighting, depending on your specific panel layout) for roughly 8 to 10 seconds.
- The screen will beep and go blank, entering diagnostic mode.
- Press any button repeatedly until the display displays Fd (Forced Defrost).
- The system will start energizing the defrost heaters, including the ice room defrost loop if equipped.
- Once the ice melts, cycle power to return the board to normal run mode.
If the frost buildup is severe, do not use an open flame, ice picks, or high-output industrial heat guns. High heat will warp the thin plastic walls of the inner liner. Use a handheld garment steamer or towels soaked in hot water to melt ice away safely.
3. Inspect the Wire Harness and Hinge Connectors
The sensor circuit wiring travels a long distance from the main PCB on the back of the cabinet, through the cabinet insulation, through the top door hinge, and into the ice compartment. Pinched, severed, or corroded pins along this route will trigger 14E instantly.
Check the Top Left Door Hinge
- Remove the protective plastic cover over the top left door hinge using a Phillips screwdriver.
- Inspect the multi-pin plastic wiring blocks.
- Look for bent terminal pins, backed-out wires, moisture buildup, or black carbon scoring.
- Unplug the harness connectors and snap them firmly back together to ensure the lock-tabs engage completely.

Check the Ice Maker Plug Inside the Ice Room
Open the ice compartment and pull the ice bucket out. Reach in and release the wire harness plug connecting the ice maker module to the ceiling of the ice box. Inspect the internal contacts for green corrosion or water droplets. Blow the harness dry with low heat if moisture is visible.
4. Test the Ice Maker Thermistor with a Multimeter
To determine if the ice maker itself is defective, test the resistance of the sensor circuit using a digital multimeter. The ice maker thermistor is a Negative Temperature Coefficient (NTC) component: its electrical resistance increases as the temperature decreases.

└──────────────────────────────────────────────┘
Testing Procedure
- Make sure power to the refrigerator is disconnected.
- Remove the ice maker assembly from the ice room to expose the wire harness connector.
- Locate the sensor wires on the connector plug. On most Samsung models, the sensor leads are identifiable as two light blue wires, or a white wire paired with a sky-blue wire.
- Set your multimeter to read Ohms (Ω) in the 200k scale (or auto-range mode).
- Insert the multimeter probe tips firmly into the female terminals corresponding to the sensor wires.
Interpreting Your Readings
Compare your multimeter reading against standard Samsung NTC resistance specifications:
- At 77°F (25°C - Room Temperature): The sensor should read roughly 5,000 Ω (5 kΩ).
- At 32°F (0°C - Ice Water Temperature): The sensor should read roughly 13,300 Ω (13.3 kΩ).
- At 0°F (-18°C - Target Freezer Temperature): The sensor should read roughly 30,000 Ω (30 kΩ) to 35,000 Ω (35 kΩ).
If your meter displays 0.00 Ω, the sensor has suffered a direct internal short. If the meter displays O.L. (Open Loop) or infinite resistance, the sensor wire has snapped or the thermistor element has broken. In either situation, the ice maker assembly must be replaced.
5. How to Replace the Samsung Ice Maker Assembly
If your diagnostic tests revealed a failed thermistor or broken internal wiring, replacing the ice maker module is the definitive repair.
Required Tools
- A #2 Phillips screwdriver
- A flathead screwdriver or stiff plastic putty knife
- A replacement Samsung ice maker assembly (verify using your fridge’s specific model tag, such as DA97-15217D, DA97-07365G, or DA97-12314A)
Step-by-Step Replacement
Step 1: Drop the Wire Harness Cover
Locate the small plastic wire housing screw on the ceiling of the ice compartment. Remove the screw with your Phillips screwdriver. Insert your flathead screwdriver into the release slot to unsnap the plastic cover and expose the wiring block.
Step 2: Unplug the Wiring Harness
Depress the locking tab on the wire harness connector firmly. Pull the male and female plugs apart. Do not pull directly on the wires; pull only by the plastic connector housing.
Step 3: Remove the Mounting Screw and Free the Unit
Look at the front support rail of the ice maker assembly. Remove the single Phillips screw securing the assembly to the side bracket. Support the bottom of the ice maker with your hand while doing this so it does not drop.

Step 4: Slide the Old Unit Out
Depress the plastic locking clip on the front left or top rail. Slide the entire ice maker assembly forward toward you, dropping it out of the rear alignment tracks. Remove the unit completely from the refrigerator.
Step 5: Install the New Assembly
Guide the back alignment tabs of the new ice maker into the rear ceiling channels. Slide the unit backward until you feel the retaining tab click into its locked position. Reinstall the front Phillips mounting screw to anchor the unit.
Step 6: Connect and Seal
Plug the wire harness securely into the ceiling connector until the lock tab clicks. Reinstall the plastic wire cover and its retaining screw. Slide the ice bucket back into position until it seats against the rear auger motor.
6. Testing the Main Control Board (PCB)
If you replace the ice maker and the 14E code persists after a reset, you must trace the circuit to the main board. The fault may lie in a failed pull-up resistor or cold solder joint on the PCB itself.

└────────────────────────────────────────────────────────┘
Testing Circuit Continuity and Voltage
- Move the refrigerator forward and unscrew the galvanized metal cover on the lower or upper rear panel.
- Locate the main control board. Refer to the electrical schematic pasted to the inside of the cover.
- Locate the connector responsible for the ice maker (often labeled CN90 or similar depending on generation).
- With power supplied to the refrigerator, set your multimeter to DC Volts.
- Carefully measure across the ice maker sensor reference pins.
You should measure a stable 5.0 volts DC between the sensor feed pin and ground when the ice maker is disconnected. If the board does not output 5V DC, the board’s voltage regulator circuit has failed. Replace the main control board.
If you measure 5V DC at the board, turn off the power. Set your meter to Ohms and test continuity between the rear board connector pins and the ice room harness pins. If the circuit is open, a wire inside the foamed cabinet wall is broken.
Preventative Modifications to Stop
14E from Returning
Once the circuit is functioning, you should take steps to address the root environmental factors that cause thermistors to fail prematurely. Moisture intrusion is the leading contributor to this issue.

└────────────────────────────────────────────────────────┘
- Apply Food-Grade RTV Silicone to the Ice Room Seams: Samsung published service bulletins recommending that technicians apply a clean bead of food-grade silicone (Part # DA81-05595A or equivalent RTV 102) along the exterior seams of the plastic ice room case. This prevents moist fresh-food air from bypassing the insulation.
- Inspect the Ice Dispenser Flapper Door: Shine a flashlight through the dispenser chute from the outside with the room dark. Look inside the ice room to see if light leaks around the flapper door. If light leaks through, warm air will constantly migrate into the ice room, causing the sensor circuit to ice up again.
- Level the Refrigerator Properly: Ensure the front feet of the refrigerator are raised slightly higher than the rear feet. This tilt ensures that French doors swing shut on their own, maintaining positive compression on the magnetic door seals.
Frequently Asked Questions
Can I replace just the 14E temperature sensor without buying the whole ice maker?
No. On nearly all modern Samsung refrigerators, the NTC thermistor is molded directly inside the ice tray frame or internal housing. Samsung does not sell the sensor as an individual replacement part. You must replace the complete ice maker assembly.
Will code 14E prevent my refrigerator and freezer from cooling?
No. Code 14E specifically isolates the ice maker sub-assembly. The main compressor, evaporator fans, and temperature controls for the fresh food compartment and lower freezer will continue to cool your food normally.
How do I clear the 14E code from my screen after fixing the sensor?
On many models, the code clears automatically once the board detects proper resistance. If it remains displayed, hold the Power Freeze and Power Cool buttons simultaneously for 6 to 8 seconds until the display chimes and resumes normal operation. Alternatively, complete a 10-minute hard power disconnect.
Why does my ice maker keep frosting over and causing code 14E?
Repeated icing indicates an air leak into the ice room. Check the rubber seal surrounding the ice bucket front cover, make sure the dispenser chute flapper closes completely, and check for unsealed gaps along the plastic walls of the ice compartment liner.
What is the difference between error code 14E and error code 40E?
Error code 14E points to an electrical fault in the ice maker’s internal mold sensor. Error code 40E (or 40C) points to a problem with the ice room fan circuit, which circulates cold air from the evaporator through the ice compartment.
Safety Precaution Notice
Before proceeding with any repair checklist: Always unplug the appliance from its electrical socket and turn off shutoff valves for incoming water (for washers and dishwashers). Discharge capacitors if working on motors.
