What Does Error F31 Mean?

The Kenmore oven F31 error indicates a malfunction in the temperature sensor circuit, often due to a shorted or defective temperature sensor probe or damaged wiring. This prevents the control board from receiving accurate temperature readings, leading to issues such as the oven not heating properly or erratic temperature behavior during baking or broiling.

Common Symptoms:

  • Oven not heating properly or not heating at all
  • Error appears when attempting to bake or broil
  • Potential erratic temperature behavior

Possible Causes

  • Shorted or defective oven temperature sensor probe (medium)
  • Damaged or pinched wiring harness between sensor and control board (medium)
  • Faulty electronic oven control board misreading the sensor circuit (medium)

How to Fix Error F31

DIY Fix Basic Checks and Power Cycle

  1. Turn off and disconnect power to the oven at the circuit breaker.
  2. Wait a minute and restore power to clear minor electronic glitches.
  3. Attempt a bake cycle to see if the F31 code persists.

Technician Only Test and Repair Temperature Sensor and Circuit

  1. Disconnect power to the oven.
  2. Access and remove the oven temperature sensor.
  3. Measure the sensor resistance with a multimeter; expected ~1080 ohms at room temp.
  4. Inspect wiring harness for shorts, pinches, or damage.
  5. Replace sensor or repair wiring as needed.
  6. Reassemble and test oven for code.
  7. If code persists, test or replace the oven’s electronic control board.

Parts needed: Oven temperature sensor, Wiring harness, Electronic control board

🛑 When to Call a Pro:
  • If you are unable to access or safely test internal components
  • If the error persists after replacing the sensor and repairing wiring
  • If control board failure is suspected
