Samsung Refrigerator Error Code Freezer Ice Pipe Heater Error (Ice Bites)

This error means the main control board has detected a fault in the Ice Bites ice maker water pipe heater circuit. The heater keeps the water supply line from freezing inside the freezer. The board expects to see approximately 72 ohms of resistance across that circuit, and the error appears when the reading falls outside that range, indicating a short, an open circuit, or a wiring problem.

The refrigerator's cooling and food preservation functions typically remain operational when this error is present, so stored food is generally not at immediate risk. However, the ice maker will not function properly, and the unheated water line may freeze solid over time. It is best to address the fault promptly to prevent further damage to the ice maker assembly.

A power reset may temporarily clear the error display, but the code will return if the underlying fault in the heater circuit is still present. Because the main PCB actively monitors the resistance of the heater circuit, the error will reappear as soon as the board performs its next diagnostic check. A reset does not repair a shorted heater, open bimetal, or broken wire.

A knowledgeable DIYer can perform the initial resistance test at the CN20 connector using a multimeter to determine whether the fault is a shorted heater, an open heater or bimetal, or a wiring issue. Replacing the pipe heater or bimetal thermostat is a moderate-difficulty repair that requires accessing the ice maker assembly. If the main PCB is suspected, professional diagnosis is recommended before purchasing a board.

Repair costs depend on which component has failed. A replacement pipe heater or bimetal thermostat typically costs between 15 and 60 dollars for the part, plus labor if you use a technician. A main PCB replacement is significantly more expensive, generally ranging from 150 to 350 dollars for the part alone. Getting a resistance reading at CN20 first helps avoid replacing unnecessary components.
