C-24 means Samsung’s temperature sensor caught the oven heating up faster than its normal rate, and Samsung ties this almost entirely to the vent at the back of the cooktop being blocked. Clearing whatever’s covering that vent, usually a pan set down nearby, is the fix in most cases. Opening and closing the door a few times while the oven is still running can help release trapped heat through the vent if the code won’t clear on its own.

Samsung Oven Error Code C-24 (Temperature Rising Too Fast)
C-24 means the oven’s temperature sensor caught the temperature climbing faster than normal, almost always because the vent at the back of the cooktop is blocked.
Meaning
Possible causes
No cause is certain until it has been checked on the appliance.
- Very likely Vent at the back of the cooktop blocked by a pan, foil, or other object
- Likely Vent partially restricted by built-up grease or debris
- Possible Temperature sensor reading incorrectly
First checks
- Check the vent area at the back of the cooktop and remove anything covering it, including pans set down nearby.
- While the oven is still cooking, open and close the door a few times, holding each open for about 3 seconds, to help release trapped warm air through the vent.
- If the code won't clear, turn off the oven and leave the door open for a minute to let it cool down before trying again.
What not to do
- Covering the back vent with cookware or trivets while the oven is on. That's the single most common cause Samsung documents for this code.
- Ignoring a recurring C-24 as just a glitch. If it keeps happening with a clear vent, the temperature sensor itself may need to be checked.
An error code varies by brand
The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.
