Direct answer
A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. 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
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord whether the feature is absent, disabled, powered but unresponsive, or showing a message. 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 the simplest supported configuration with unrelated accessories and optional services removed. 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. Restore only the failed prerequisite or path; do not change working layers.
Verify and stop safely
ReversibleRepeat from a cold start and complete one normal use. Stop for runaway heat, smoke, gas odor, arcing or breaker trips.

Exact questions
Common follow-ups
What should I check first when oven temperature control has this problem?+
Measure a standardized empty-oven cycle with an appropriate thermometer.
Why not factory-reset immediately?+
The useful boundary is cookware/rack/measurement versus sensor, calibration and heating element/burner. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
stop for runaway heat, smoke, gas odor, arcing or breaker trips.
