Samsung Range Error Code C-23

The C-23 code on a Samsung range means the control board has detected a short circuit in the meat probe sensor while the oven is running. The probe is a thermistor that should measure approximately 50K ohms of resistance at room temperature, and a shorted probe reads significantly lower than that. The oven triggers this code to alert you to a faulty probe circuit so it can stop the cooking cycle before inaccurate temperature readings affect your results.

You should not use the oven in probe mode while C-23 is active, since the control board cannot accurately monitor food temperature with a shorted probe. If the oven allows standard bake or broil functions without the probe connected, those modes are generally unaffected by this fault. Disconnect and remove the probe entirely before running the oven in any mode until the issue is resolved.

Disconnecting power to the range for a few minutes may temporarily clear the C-23 code, but the error will return as soon as the oven detects the shorted probe circuit again during operation. A permanent fix requires resolving the underlying short, either by replacing the probe, cleaning the probe jack, or repairing the harness. Resetting without addressing the cause is not a long-term solution.

Yes, this repair is manageable for a knowledgeable DIYer with a multimeter. Start by disconnecting power, unplugging the meat probe from the oven cavity, and measuring resistance across the probe terminals. If the reading is well below 50K ohms, replacing the meat probe is the fix. If the probe tests correctly, further inspection of the probe jack and wiring harness is needed before considering a control board replacement.

If the meat probe is the cause, replacement probes typically cost in the range of $20 to $60 for parts, making this one of the more affordable range repairs. If the wiring harness needs replacement, parts and labor together may run $80 to $200 depending on the service provider. A control board replacement, if needed, is the most expensive outcome and can range from $150 to $400 or more for parts alone.
