Possible Causes

Partially failed bake element, incorrect oven temperature sensor reading, poor door seal causing heat loss, convection fan not running

How to Fix / Troubleshooting

Safety: Disconnect power before testing elements or sensors.

  • Visual element check: Inspect the bake element for thin spots, blisters, or areas that do not glow evenly when heating.
  • Test bake element: Measure resistance and compare to spec. A significantly higher resistance than normal can cause weak heating; replace if out of range.
  • Check door gasket: Inspect the door seal for gaps, tears, or hardened sections. Replace if it does not seal evenly all around.
  • Convection fan: In convection mode, ensure the fan runs. If not, test and replace the fan motor.
  • Sensor calibration: Test the oven temperature with an accurate oven thermometer. If consistently off by a similar amount, use the oven's calibration function (if available) or replace the temperature sensor.
