Possible Causes

Weak bake element, failed convection element (if equipped), inaccurate oven temperature sensor, door gasket leak

How to Fix / Troubleshooting

Safety First: Turn off power before testing elements or sensor.

  • Verify with thermometer: Use an oven thermometer to compare actual temperature to the set temperature.
  • Inspect bake element: Look for cold spots or uneven glow (on electric models). Test resistance; replace if open or visibly damaged.
  • Check convection element and fan: On convection models, ensure the rear convection element heats and the fan runs.
  • Test temperature sensor: Measure sensor resistance at room temperature (~1050–1100 Ω). Replace if out of spec.
  • Inspect door gasket: Check for tears or gaps in the gasket that allow heat to escape; replace if damaged.
