Samsung Refrigerator Error Code Ice Pipe Heater Error (Cubed Ice)

This error means the main control board has detected an open circuit, short circuit, disconnection, or contact failure in the cubed ice pipe heater circuit. The heater is designed to prevent ice jams in the cubed ice dispenser chute. The board monitors the heater's resistance and flags this error when the circuit does not respond within the expected 24 ohm range. It requires electrical diagnosis at the CN20 connector on the main PCB to pinpoint the fault.

A power reset may temporarily clear the error from the display, but if the underlying electrical fault in the heater circuit remains, the error will return once the control board runs its diagnostic cycle again. A reset is not a repair and should only be used to confirm whether the fault is intermittent or persistent. Proper resistance testing of the heater circuit is required to resolve the error permanently.

Repair costs vary depending on which component has failed. Replacing a wiring harness or heater element typically runs in the range of $50 to $150 for parts, plus labor if a technician is involved. If the main PCB is at fault, parts alone can range from $100 to $300 or more depending on the model. Diagnosing the fault yourself using a multimeter before calling a technician can help avoid unnecessary part replacement costs.

Start by disconnecting the CN20 wire harness from the main PCB and measuring resistance between pins 19 and 23. The reading should be 24 ohms within plus or minus 7 percent, which is approximately 22.3 to 25.7 ohms. If the resistance is out of range or reads as open or shorted, the heater element or wiring harness needs replacement. If resistance is correct, inspect the connector for loose pins or poor contact before considering PCB replacement.

This error does not typically present an immediate safety hazard to the home or occupants. The affected component is a low-voltage heater within the ice dispenser pathway. However, a shorted heater circuit should not be ignored, as electrical shorts in any appliance can worsen over time. The refrigerator's cooling function is generally not affected, but cubed ice dispensing may be unreliable until the fault is corrected.
