C2 concerns the IGBT sensor, which watches the temperature of the power transistors that drive the induction coils. Samsung shows C2 when that sensor reads open or shorted during cooking. Samsung cooktop display What to do when C2 shows on the cooktop ### Kind of code Induction power and coils An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then. ### Usually leads to Induction board and coil repair Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls. ### Shows up as Cooktop Element Not Heating A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil. ### Make Samsung A Korean electronics maker that sells built-in cooktops in the US, induction among them. ### Source Samsung NZ30A3060UK induction cooktop user manual (English), Information codes Printed in the information code tables of Samsung's manuals for the NZ30A3060UK and NZ30K7880US induction cooktops (both carry a U.S.A. warranty page). ## Before you book, in this order. Each step comes from Samsung's own guidance for C2 on its cooktops. Follow it to the end: the last card says whether this is a visit. 01 Restart the cooktop, then cut power for at least 30 seconds if C2 remains. 02 If C2 comes back once the power is restored, switch the breaker off again and leave the cooktop unused until the visit. 03 Book a visit if it keeps returning. ### Still there? It usually turns into [induction board and coil repair](https://cooktoprepair.center/services/induction-board-and-coil-repair/). Book with the code and the model number. ### What not to do C2 is not about the glass or the pan; it is inside the power electronics. It is also different from C0, which concerns the top sensor under the glass. ## What you may notice with it. The cooktop problems C2 tends to arrive with. Answer these at the cooktop before anyone is booked.

Restart the cooktop, then cut power for at least 30 seconds if C2 remains. If it comes back, it needs a visit. ### What is the IGBT on a Samsung induction cooktop? It is the power switch that drives the coil. C2 means the sensor watching its temperature reads wrong. ### Will C2 go away if I change pans? No. It does not involve the cookware. ### Why does Samsung list C2 as both an open and a shorted IGBT sensor? The information code table gives two lines for C2: the IGBT sensor reads open, or it has a short, while a zone is operating. Both mean the cooktop cannot trust the temperature of its power transistors. A technician tests the sensor and its wiring to tell the two apart. --- **[Read on the site: Samsung induction cooktop showing C2 | CooktopRepair.center](https://cooktoprepair.center/error-codes/samsung-c2/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
