Samsung Range Error Codes

Samsung Range Error Code: C-20

Unplug the range and check the wire harness connections between the oven temperature sensor and the main control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, measure the resistance of the oven temperature sensor using a multimeter. You should measure around 1,100 ohms of resistance at room temperature. Replace the oven temperature sensor if resistance is off by more than 200 ohms.
