On Samsung ranges and wall ovens, C-d0/C-d1/C-d2 and C-20/C-21/C-22 are door or key errors, C-10 is a temperature sensor reading, C-24 means the oven heated too fast (often a blocked vent), C-F0 is a communication error, -dC- or -dE- means the Flex Duo partition isn't seated, bAd LinE means a power wiring problem and tESt means demo mode. Turn the range off and on, then switch the breaker off for 30 seconds; codes that return need a technician.
| Code | What it means | What you can do |
|---|---|---|
| C-d0 / C-d1 / C-d2 | Door or key error | Check the door closes; breaker reset. Repeats need diagnosis. |
| C-20 / C-21 / C-22 | Door or key error | Breaker reset; repeats need diagnosis. |
| C-10 | Temperature sensor reading problem | Ignore during self-diagnosis; reset if it appears while cooking. |

| C-F0 | Communication error between electronics | Power reset; update software via SmartThings on connected models. |
| -dC- / -dE- | Partition not installed correctly (Flex Duo) | Reinstall it fully in the correct rack position. |

Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
Turn it off and on; if it returns, switch the breaker off for 30 seconds.
It's in demo mode and won't heat. Turn demo mode off per the manual.
The oven heated faster than expected — usually a blocked vent.
