GE Range Error Code 331

Error code 331 means the control board has detected an open circuit in the oven temperature sensor. The sensor is the probe inside the oven that measures cooking temperature, and an open circuit means the board is receiving no signal from it. If the fault is present for roughly three minutes, the error is written to the board's memory and will disable both the oven and the cooktop until the problem is corrected.

The range is designed to prevent use when this fault is active. After the error is stored to memory, both the oven and the cooktop burners are disabled by the control board. You should not attempt to bypass these safety shutoffs. Stop using the appliance and diagnose the sensor fault before resuming cooking.

If the oven temperature sensor is the cause, parts typically range from around $20 to $60 depending on the specific model, and the repair is considered straightforward for someone comfortable with basic appliance work. If a technician is needed, expect to pay a service call fee plus labor, bringing the total to roughly $100 to $250 in most markets. Control board replacement, if needed in rarer cases, will cost considerably more.

A power reset may temporarily clear the display, but if the underlying sensor fault is still present, the code will return. More importantly, once the code has been active for approximately three minutes, it is stored in EEPROM memory on the control board. That means simply cycling power will not restore normal operation. The sensor or its wiring must be repaired or replaced first.

Start by disconnecting power to the range for a minute, then restoring power to see if the 331 code reappears. If it does, the oven temperature sensor should be tested with a multimeter at the sensor connector. A reading of infinite resistance confirms an open circuit in the sensor, and the sensor should be replaced. Also inspect the wiring harness from the sensor to the control board for any burned or disconnected wires.
