An appliance that fails partway through a cycle and sometimes completes normally usually points to a specific stage — fill, wash, spin, heat or dry — not total failure. 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

0 of 4 completedCapture the exact failure state
ReversibleNote exactly which stage the cycle stops or errors at, and whether it's the same stage each time. 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. Run the specific stage in isolation where the appliance allows it, and repeat with a different, similar-sized load. 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 loading, supply or setting proven to affect that one stage, or arrange service for a component fault confirmed at that stage.
Verify and stop safely
ReversibleRun two complete normal cycles in a row and confirm the same stage no longer fails. Stop for runaway heat, smoke, gas odor, arcing or breaker trips.
