Samsung refrigerator with error code 26C or 26E

As an expert technician, I have diagnosed the Samsung refrigerator with error code 26C or 26E: General cubed ice maker function error.

Error Explanation

The 26C or 26E error code indicates a failure in the ice maker’s harvest cycle. This occurs when the Main PCB (Power Control Board) detects that the Ice Maker Assembly is unable to complete its rotation, fail to return to the “Home” position, or the heater used to release the ice cubes is not functioning. This is frequently caused by a mechanical jam, a failed heater, or a faulty motor within the assembly itself.

Samsung refrigerator with error code 26C or 26E: Troubleshooting Instructions

1. Perform a Manual Reset: Locate the Test button on the side or front of the Ice Maker Assembly. Press and hold this button for 3 to 5 seconds until you hear a “beep.” The ice maker should begin a harvest cycle (rotating the tray). If it does not move or makes a grinding noise, the motor is likely defective.
2. Inspect for Ice Jams: Check the Ice Room for any frost buildup or stray ice cubes that may be blocking the tray’s rotation. If the unit is “iced over,” use a steamer to clear the ice. Do not use a hair dryer, as the high heat can melt the plastic liners.
3. Check the Wiring Harness: Ensure the wiring harness connecting the Ice Maker Assembly to the refrigerator ceiling is securely plugged in and that no wires are pinched or frayed.
4. Test the Heater and Motor: Using a multimeter, check the internal components of the Ice Maker Assembly for continuity and proper resistance.
5. Inspect the Water Inlet Valve: If the ice maker rotates but no ice is produced, ensure the Water Inlet Valve is receiving a signal to fill the tray after the harvest cycle completes.

Expected Ohmic/Resistance Values

To confirm a component failure, use a multimeter to test the following:

• Ice Maker Heater: 70-110 Ω. (If the circuit is open/infinite, the heater cannot release the ice, causing the motor to stall).
• Water Inlet Valve Solenoid: 300-400 Ω.
• Ice Maker Thermistor: Approximately 5k Ω at 77°F (25°C) or 13k Ω at 32°F (0°C).

Estimated Repair Cost

• Ice Maker Assembly: $110 – $210 USD.
• Water Inlet Valve: $40 – $85 USD.
• Main PCB: $150 – $250 USD.
• Note: In 90% of cases, replacing the entire Ice Maker Assembly resolves the 26C or 26E error.

Safety Warnings

Warning: Always disconnect the refrigerator from the power source before attempting to remove or test internal components.
Warning: Turn off the household water supply valve before servicing the Water Inlet Valve to prevent flooding.
Warning: Be cautious of sharp metal edges on the back of the refrigerator and the internal evaporator covers.

Repair Difficulty

DIY (Intermediate): Replacing the Ice Maker Assembly is a common DIY task. It typically involves removing one or two screws and disconnecting a single wiring harness. However, if the error persists after replacement, a professional may be needed to diagnose a faulty Main PCB or an internal wiring failure.
