Error codeC-10
ApplianceRange
Quick answer
C-10 can appear during a SmartThings self-diagnosis when the oven starts very cold or very hot. It is not a defect.
Model compatibility: Samsung reuses codes across series and model years, so C-10 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
C-10 can appear during a SmartThings self-diagnosis if the oven starts very cold or very hot; not a defect.
C-10 can show up while you run a self diagnosis on the oven through the SmartThings app. It should not appear during regular cooking, and on its own it does not point to a problem with the oven.
Why it appears during the test
If the oven is very cold or very hot at the start of the test, the sensor’s hardware limitation can trigger the code. That is not an actual defect.
What to do
If C-10 appears during the test but the oven heats normally, ignore it. It does not affect usability or performance. If it appears during cooking, by itself and without a diagnosis running, it could be a problem. Try resetting the oven.
Other range codes
Sensor trouble is also covered by the sensor malfunction codes, and C-24 is the code for temperature rising faster than normal.
