Error codeC-24
ApplianceRange
C-24 appears when the temperature sensor notices the oven warming faster than it should. Samsung usually traces that to a vent at the rear of the cooktop that is covered, wholly or partly.
Clearing it
Lift off whatever sits on the vent, a pan for instance.
Cooking can continue while you swing the door open and shut a few times, about 3 seconds per swing, letting warm air out through the vent.
Alternatively, switch the oven off with the door left ajar for one minute so it cools.
Different entries
Do not confuse it with the C-20 to C-22 sensor codes, a separate group, or with C-10, which can appear during a SmartThings self-diagnosis.
Range repair for San Francisco kitchens
When C-24 comes back even with the vent clear, call (415) 969-6153 about Samsung range and oven repair in San Francisco and the Bay Area. Mention what sat on the cooktop and the model number.
Model compatibility: Samsung reuses codes across series and model years, so C-24 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-24 on a Samsung range means the oven is heating faster than normal, usually because the cooktop's rear vent is blocked.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
