An appliance problem starting right after a house move, a new detergent or additive, or a water/gas/power supply change should be checked against that specific change first. 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 what changed — installation, supply type or product used — and confirm it worked immediately before. 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. Test with the previous product or a factory-recommended one, or verify the new supply connection matches the appliance's requirements. 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 installation, switch back to a compatible product, or arrange service for a supply mismatch that cannot be user-corrected.
Verify and stop safely
ReversibleRun one complete normal cycle under the new conditions and confirm normal results. Stop for runaway heat, smoke, gas odor, arcing or breaker trips.
