Symptoms

  • Oven does not heat at all
  • Oven takes too long to preheat
  • Oven temperature lower than setting
  • Food undercooked or takes too long
  • Uneven cooking results

Possible Causes

Faulty heating element (electric)

common

The bake or broil element has burned out.

Weak igniter (gas)

common

The igniter cannot get hot enough to open the gas valve.

Faulty temperature sensor

occasional

The sensor is not accurately reading oven temperature.

Control board failure

occasional

The electronic control is not sending power to heating components.

Gas valve issue (gas ovens)

rare

The gas safety valve is not opening properly.

Calibration needed

common

The oven temperature has drifted from the set point.

Diagnostic Steps

  1. 1Check that the oven is set to the correct mode (bake, not broil or warm)
  2. 2Verify the temperature setting
  3. 3For electric: Look at the heating elements - do they glow when heating?
  4. 4For gas: Listen for igniter clicking and look for glow
  5. 5Test with an oven thermometer
  6. 6Check for error codes on the display
