Samsung Washer 10 Error Code: Causes and Fixes

The C-10 error on your Samsung Microwave means there is a gas sensor error or malfunction. This code indicates the microwave’s internal gas detection system has detected an abnormal condition or the sensor itself has failed.

What the C-10 error means

The C-10 error code indicates a problem with your Samsung microwave’s gas sensor system. This sensor is a safety component designed to detect gas leaks or abnormal gas concentrations near the appliance. When the sensor detects an issue or malfunctions itself, the microwave displays this error code and typically shuts down operation to prevent potential safety hazards. This error is most commonly found in Samsung over-the-range microwaves with built-in ventilation systems.

Common causes

• Faulty or damaged gas sensor that needs replacement
• Loose or corroded electrical connections to the gas sensor
• Control board malfunction sending incorrect signals to the sensor
• Actual gas leak detected by a functioning sensor (rare but serious)
• Moisture or debris buildup affecting sensor readings
• Power surge or electrical issue causing sensor calibration problems

How to fix the C-10 error

1. Check for actual gas leaks first: Before attempting any repairs, ensure there are no gas odors near your microwave or range. If you smell gas, do not use any appliances, ventilate the area, and contact your gas company immediately. This is a safety priority.
2. Reset the microwave: Unplug the microwave from the power outlet or turn off the circuit breaker for 2–3 minutes. This allows the control board to reset and may clear temporary sensor glitches. Restore power and test if the error clears.
3. Inspect sensor connections: With power disconnected, access the microwave’s internal components by removing the outer casing. Locate the gas sensor (typically near the ventilation area) and check all wire connections for looseness, corrosion, or damage. Clean and reseat any loose connections.
4. Test the gas sensor: Using a multimeter, test the gas sensor for proper resistance values according to your model’s service manual (typically 10–50 ohms at room temperature). If readings are infinite or zero, the sensor has failed and requires replacement.
5. Replace the faulty sensor: Order the correct gas sensor for your Samsung microwave model. Disconnect the old sensor, install the new one following the wiring diagram, and secure all connections. Reassemble the microwave and test operation.
6. Contact professional service: If you’re uncomfortable working with gas appliances or internal microwave components, or if the error persists after replacing the sensor, contact a qualified appliance technician or Samsung service center for professional diagnosis and repair.
