Samsung Range C-10 and F-22 Error Codes — Sensor and Calibration Fix

If your Samsung range or oven is flashing C-10 or F-22 on the display, don’t panic. These are two of the most common error codes on Samsung ranges, and both are fixable with basic tools and a little patience. This guide covers what each code means, how to diagnose the root cause, and step-by-step instructions to get your oven baking again.

Quick Reference

What Does C-10 Mean?

C-10 (sometimes shown as C10 or C-10) means the oven temperature sensor — a thermistor — has failed or has an open circuit. The control board can’t read the oven temp, so it shuts down the heating elements for safety. This is essentially a dead sensor or a broken wire going to it.

What Does F-22 Mean?

F-22 means the oven calibration data has become corrupted, or the main control board has developed an internal fault. It’s less common than C-10 but can be more frustrating because it sometimes comes back after a simple reset.

Fix 1: Reset the Range

A full power cycle clears transient errors and may clear an F-22 calibration glitch.

1. Unplug the range or flip the breaker off.
2. Wait 5 full minutes (press the oven buttons during this time to discharge residual power).
3. Plug it back in or flip the breaker on.
4. Set the clock and see if the code returns.

If C-10 or F-22 is gone for good, you’re done. If it comes back, move to Fix 2.

Fix 2: Test the Oven Temperature Sensor with a Multimeter

The oven sensor looks like a metal probe about 4–6 inches long mounted in the back wall of the oven cavity. It connects to the control board with two wires.

You’ll need a multimeter for this step.

1. Disconnect power — unplug the range or flip the breaker.
2. Access the sensor — open the oven door and remove the rear interior panel if needed. The sensor is usually at the top rear of the oven cavity held by one or two screws.
3. Remove the sensor — unscrew it and gently pull it forward so you can disconnect the wire harness.
4. Test resistance — set your multimeter to ohms (Ω). Touch the probes to the two terminals on the sensor.
5. Read the value at room temperature (about 70°F): you should see around 1080–1100 ohms.

If you get OL (open loop) or 0, the sensor is dead and needs replacement. If the reading is out of range (under 900Ω or over 1300Ω at room temp), the sensor is drifting and should be replaced.

When you’re ready to buy a replacement, grab a Samsung oven temperature sensor (thermistor).

Fix 3: Replace the Oven Temperature Sensor

If the sensor tested bad, swapping it takes about 15 minutes.

1. Order the correct part: look up your model number (sticker inside the oven door or on the back of the range) and match it to a compatible sensor.
2. Disconnect power.
3. Unplug the old sensor from the wire harness.
4. Remove the mounting screw and pull the sensor out.
5. Install the new sensor — insert the probe, tighten the screw, reconnect the wire harness.
6. Restore power.

This is the most common fix for C-10. If the new sensor doesn’t clear the code, the issue might be in the wire harness or the control board itself.

Fix 4: Recalibrate the Oven

If F-22 appeared after a power outage or surge, the calibration data may have been scrambled. Here’s how to factory recalibrate:

1. Press Bake and Broil simultaneously for 3 seconds. Some models respond to Bake + Broil + 0 held for 3 seconds.
2. Wait for the display to show a temperature value or “0” (this may take a few seconds).
3. Enter a calibration offset of 0°F to return to factory defaults.
4. Press Start or Clear to lock in the change.
5. Test by setting the oven to 350°F and checking if the code returns.

Not all Samsung range models expose calibration through the touchpad. If this sequence doesn’t work, check your user manual for the exact procedure.

Fix 5: Replace the Main Control Board

If you’ve done Fixes 1–4 and C-10 or F-22 keeps coming back, the main control board (PCB) may be faulty. This is the last resort and costs around $100–$250 for the part.

1. Find your model number and order a Samsung range main control board.
2. Disconnect power.
3. Remove the back panel of the range to access the board.
4. Take a photo of the wiring before disconnecting anything.
5. Unplug the ribbon cables and wire harness connectors from the old board.
6. Install the new board, matching every connection to your photo.
7. Restore power and test.

Control board swaps require some confidence with wiring. If you’re not comfortable, call a technician.

Parts You Might Need

• Samsung oven temperature sensor (thermistor)
• Digital multimeter
• Samsung range main control board
• Oven wire harness (check model compatibility)

When to Call a Professional

If the C-10 or F-22 code persists after replacing the sensor and checking the wiring, the issue is likely on the control board. At that point, weigh the cost of a service call (around $150–$250 + parts) against the value of your range. An experienced tech can run diagnostics you can’t do at home.
