Samsung Range Error Code IGBT Sensor Short

This error indicates that the temperature sensor monitoring the IGBT inside the induction inverter module has produced an analog-to-digital value below 10, which the control board interprets as a short circuit. The IGBT is the high-power switching component that drives induction heating, and its sensor must read around 10K ohms at 25 degrees Celsius to be considered functional. The range shuts down to prevent unmonitored overheating of this component. Possible causes include a loose wire harness, a shorted sensor, or a defective control board.

No, you should not attempt to operate the induction cooktop while this error is active. The error means the range cannot reliably monitor the temperature of the IGBT, which is a critical safety function. Continued use without a functioning temperature sensor could result in overheating and damage to the inverter module or other components.

Repair costs vary depending on the root cause. If only the sub wire harness needs reseating or replacement, costs are minimal, typically in the range of a service call fee plus a small parts cost. If the Assy-Inverter Module requires replacement, parts and labor combined can range from roughly 150 to 400 dollars or more depending on the model and local labor rates. A defective PCB replacement falls in a similar cost range.

A knowledgeable DIYer can start by inspecting and reseating the sub wire harness that runs between the Assy-Inverter Module and the Assy Touch PCB, checking that the wire sequence matches the schematic. If the wiring is intact, measuring the sensor resistance with a multimeter (expected value: 10K ohms at 25 degrees Celsius) will confirm whether the inverter module sensor is shorted. Replacing the inverter module or PCB involves working near high-voltage capacitors, so those steps are best handled by a qualified technician.

A power reset may temporarily clear the error display, but the fault will return as soon as the range runs a self-diagnostic cycle if the underlying hardware problem has not been fixed. Because the error is triggered by an out-of-range sensor resistance reading, clearing it requires correcting the wiring connection or replacing the defective component. A reset alone is not a repair.
