An appliance problem limited to one cycle, load, zone or operating condition should be separated from a component that fails every time. For oven temperature control, first measure a standardized empty-oven cycle with an appropriate thermometer.
What this covers
- oven temperature control with this exact failure state
- Diagnosis across cookware/rack/measurement versus sensor, calibration and heating element/burner

Try in this order
0 of 4 completedCapture the exact failure state
ReversibleName the failing cycle, load, zone or operating condition and one safe condition that still works. Expected behavior: cycle around the setpoint after full preheat with normal variation.
Isolate the component boundary
ReversibleMeasure a standardized empty-oven cycle with an appropriate thermometer. Change only the cycle, load, temperature, zone or installation condition while keeping the appliance setup unchanged. Boundary to separate: cookware/rack/measurement versus sensor, calibration and heating element/burner.
Correct only the proven cause
ReversibleAdjust supported calibration modestly or service large/repeatable error. Correct the isolated selection, loading, installation or operating condition.
Verify and stop safely
ReversibleRepeat the safe controlled cycle and compare the known-working condition. Stop for runaway heat, smoke, gas odor, arcing or breaker trips.
