GE Range Error Code 331

Error code 331 on a GE range indicates that the control board has detected an open circuit in the oven temperature sensor, also called the oven sensor or RTD (resistance temperature detector). The oven sensor is a probe mounted inside the oven cavity that continuously reports temperature data to the electronic control board by varying its electrical resistance. A properly functioning sensor reads approximately 1080 ohms at room temperature. An open circuit means the electrical path through the sensor has been broken entirely, so no resistance reading can be communicated to the control board.

When the control board detects this open condition, it triggers error code 331. Critically, if the fault persists for approximately three minutes, the board writes the error to its EEPROM memory. Once stored in EEPROM, the fault disables not only the oven but also the cooktop burners, rendering the entire appliance inoperative until the fault is resolved. This EEPROM storage behavior is an important distinction because it means the range will not simply resume normal operation after a power cycle if the sensor problem has not been corrected.

The first diagnostic step is to disconnect power to the range, then restore power and check whether the 331 code reappears on the display. If the code returns immediately, the oven sensor is the primary suspect and should be replaced. The sensor can also be tested with a multimeter at the sensor connector to confirm an open circuit reading before ordering parts.
