Samsung Range Error Code C0

The C0 error code on a Samsung range indicates a top sensor open or short error. The control board monitors the A/D value from the upper oven temperature sensor, and when that value rises above 252 or drops below 10, the code is set. It can be caused by a faulty sensor, wiring problems, or a defective control board.

You should not use the oven while the C0 error is active. This code means the control board cannot get a reliable temperature reading from the top sensor, so it cannot regulate oven heat accurately. Continuing to operate the oven in this condition is both a potential safety risk and could cause further damage to components.

Resetting the range by cutting power at the breaker for a few minutes may temporarily clear the C0 code, but it will return if the underlying fault is still present. A reset does not repair a failed sensor, damaged wiring, or a defective board. Proper diagnosis and repair of the root cause is necessary to permanently resolve the error.

A knowledgeable DIYer can start by inspecting the sensor wiring and connectors for obvious damage or disconnection, which requires no parts. Testing the thermistor sensor with a multimeter is also within reach for someone comfortable with basic electrical diagnostics. If the sensor needs replacement, it is a relatively straightforward repair. A defective PCB is a more advanced fix and may be better handled by a qualified technician.

If only the temperature sensor needs replacement, parts typically cost in the range of $20 to $60, making it one of the more affordable repairs. A replacement control board is significantly more expensive, often ranging from $150 to $350 or more for parts alone. Adding professional labor will increase the total cost, generally bringing a service call into the $200 to $500 range depending on the fault and your location.
