Samsung uses C-20 when the control loses a sane reading from the oven sensor: the electric range manual lists it for a sensor that is open while the oven runs and for one that is shorted. With no trustworthy reading, the control stops the oven from heating. Samsung range display What to do when C-20 shows on the range ### Kind of code Temperature sensor The oven sensor sent a reading the control would not accept, or one that climbed well past the setting. A loose plug or a sensor that has drifted is ruled out before the control board, and a temperature that keeps rising means the range is switched off at the breaker first. ### Usually leads to Temperature sensor and thermostat repair A range oven that bakes hot, bakes slow, takes forever to preheat or posts a sensor code, traced to the sensor probe, the thermostat or the calibration. ### Shows up as Range Oven Not Heating The burners or elements on top work, but the oven below stays cold, heats only a little, or never finishes preheating. ### Make Samsung A Korean electronics group whose freestanding and slide-in ranges run on gas, electric and induction. ### Source Samsung NX60A6711SS gas range user manual DG68-01338A-09, Information codes (Samsung download center; table read from the rendered page) C-20 is printed in both the NX60A6711SS gas manual and the NE63A6711 electric manual. ## Before you book, in this order. Each step comes from Samsung's own guidance for C-20 on its ranges. Follow it to the end: the last card says whether this is a visit. 01 Press OFF/CLEAR and start the oven again. 02 If C-20 comes back, switch the range off at the breaker for at least 30 seconds, then restore power. 03 Book a visit if the code survives the power reset; the sensor and its wiring are tested with a meter. ### Still there? It usually turns into [temperature sensor and thermostat repair](https://rangerepair.center/services/temperature-sensor-and-thermostat-repair/). Book with the code and the model number. ### What not to do C-20 is about the sensor signal, not about the oven running hot. An oven that is actually too hot is C-21. ## What you may notice with it. The range problems C-20 tends to arrive with. Answer these at the range before anyone is booked.

Press OFF/CLEAR and start the oven again. If it comes back, it needs a visit. ### Can I keep cooking on the burners while my Samsung range shows C-20? C-20 concerns the oven sensor, and the manual ties the fix to restarting the oven and resetting power. Samsung does not say the range top is locked out, but if the code returns after a breaker reset, the oven needs a sensor check before you bake again. ### Why did C-20 come back a day after I reset my Samsung range? A reset only clears the message; it cannot repair a sensor that opens or shorts once it warms up. A code that returns points to the sensor or its connector, which a technician can measure. --- **[Read on the site: Samsung range showing C-20 | RangeRepair.center](https://rangerepair.center/error-codes/samsung-c-20/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
