Oven displays F31 and may not heat or may shut off

Safety first: Turn off power at the breaker before working on the range.

• Access and test sensor:
  • Remove the oven temperature sensor as for F30.
  • Measure resistance at room temperature with a multimeter.
  • A reading near 0 Ω or very low indicates a shorted sensor.
• Inspect harness for shorts:
  • Follow the sensor wires through the rear of the oven to the control board.
  • Look for areas where the harness may be pinched against metal or melted by the oven.
  • Repair any damaged insulation and reroute away from hot or sharp surfaces.
• Replace components as needed:
  • Replace the oven temperature sensor if it reads shorted.
  • If sensor and wiring are good but F31 persists, the electronic oven control (EOC) may be faulty and require replacement.
• Final test: Restore power and run a bake cycle. Confirm stable temperature and no F31 code.
