What Does Error F31 Mean?

The Viking oven F31 error indicates a malfunction in the temperature sensor or its circuit, leading to erratic temperature readings and inconsistent cooking performance. This error often arises when the oven attempts to heat but fails to reach or maintain the correct temperature. A faulty temperature sensor or issues with the wiring harness may be the root cause, affecting the oven's ability to provide accurate temperature feedback to the control board.

Common Symptoms:

  • Error displayed when oven tries to heat
  • Oven fails to reach or regulate temperature
  • Error persists after simple resets

Possible Causes

  • Faulty oven temperature sensor (RTD/thermistor) or shorted sensor circuit (medium)
  • Wiring harness issue between temp sensor and control board (medium)
  • Control board failing to read sensor signal (low)

How to Fix Error F31

DIY Fix Basic reset and visual check

  1. Turn off oven power via breaker or unplug for 5–10 minutes
  2. After power is off, visually inspect inside oven for obvious damage to temperature sensor or wiring if accessible
  3. Restore power and test if code returns

Technician Only Diagnose and repair sensor circuit

  1. Disconnect power to oven entirely at breaker
  2. Measure temperature sensor resistance with a multimeter
  3. Inspect wiring harness for shorts, chafing, melted insulation or loose connections
  4. Replace faulty temperature sensor if resistance is outside expected range
  5. If sensor and wiring OK, test control board input signal and replace board if defective

Parts needed: oven temperature sensor (RTD/thermistor), wiring harness, control board

🛑 When to Call a Pro:
  • If error persists after sensor and wiring checks
  • If control board diagnosis/replacement is required
  • If user is uncomfortable performing electrical diagnosis
