Possible Causes

Temperature sensor drifted out of range, Poor sensor connection at control, Incorrect oven calibration setting, Control board ADC failure

How to Fix / Troubleshooting

Safety: Turn off power before accessing internal components.

Verification:

  • Use an accurate oven thermometer to compare actual temperature to the set temperature at 350°F.
  • If the oven is consistently off by more than 25°F, check the temperature sensor resistance at room temperature and at a known elevated temperature (per Wolf specs).
  • Inspect and reseat the sensor connector at the control board.

Corrective actions:

  • Use the oven's temperature calibration feature (if available) to adjust by ±35°F.
  • Replace the oven temperature sensor if resistance is out of spec or unstable.
  • If calibration and sensor replacement do not resolve E15, replace the main control board.
