Direct answer
Measure with a stable oven thermometer over multiple cycles at one setpoint. Use the user offset only for a consistent average bias within the model's allowed range; large swings, runaway heat or error codes need service.
What this covers
- An oven with a documented user temperature-offset or calibration setting
- The exact condition described in the direct answer
- Customer-accessible observations and controls
What it does not cover
- ×A different model, region or software interface that contradicts the cited source
- ×A displayed code with a separate manufacturer meaning
- ×Live electrical, gas, sealed-system or battery-cell repair
Establish the exact starting state
ReversiblePlace a reliable thermometer centrally and preheat fully without opening the door repeatedly.
Separate the fault or decision boundary
ReversibleAverage several heating cycles and compare multiple rack positions rather than one instantaneous reading.
Apply the narrowest correction
ReversibleApply a small documented offset only when the average error is consistent.
Verify before escalating
ReversibleRepeat the same test after calibration and confirm cooking results without exceeding the allowed offset.

Common follow-ups
What is the short answer to “Calibrate an oven temperature without masking a real fault”?+
Measure with a stable oven thermometer over multiple cycles at one setpoint. Use the user offset only for a consistent average bias within the model's allowed range; large swings, runaway heat or error codes need service.
What should I check before changing anything?+
Place a reliable thermometer centrally and preheat fully without opening the door repeatedly.
How do I know the action worked?+
Repeat the same test after calibration and confirm cooking results without exceeding the allowed offset.
When should I stop?+
Stop for runaway heat, smoke, damaged elements, gas odor or a fault code; calibration is not a repair for unsafe regulation.
