Narrow it down
What this symptom can tell you
Food is consistently underdone
The oven may be running cool, losing heat through the door, or being opened too often.
Food browns too quickly
Rack position, dark cookware, convection settings, or calibration may be raising effective heat.
Results vary by rack
Airflow, rack placement, foil, cookware size, or convection may be affecting circulation.
These observations narrow the next safe check; they do not confirm a failed part. Use the full model number and any displayed code before ordering parts or authorizing repair.
Try these checks in order
Stop when a step does not match your appliance, the exact manual, or your comfort level.
- 1
Confirm full preheat
Wait for the preheat signal and several additional minutes if the manual recommends heat stabilization.
What you want: The cavity reaches a stable cooking condition before food enters. - 2
Use the recommended rack position
Move the rack to the position specified for the food and mode.
What you want: Food is centred with room for air movement. - 3
Remove airflow obstructions
Do not line the oven floor or cover complete racks with foil unless the manual explicitly allows it.
What you want: Air can circulate around the pan. - 4
Compare cookware and mode
Dark pans, glass, convection, and air-fry modes can change browning and timing.
What you want: The cookware and mode match the recipe. - 5
Review model calibration
Use only the temperature-offset procedure in the exact manual.
What you want: Any adjustment stays within the manufacturer’s allowed range.
Possible categories
What may be causing the problem
- Incomplete preheating or frequent door opening.
- Rack position, cookware colour or material, convection settings, or blocked airflow.
- A door seal or latch condition that allows heat loss.
- A temperature sensor, control, element, igniter, or calibration issue requiring service.
Stop and arrange help when
- The oven overheats, will not stop heating, or shows a high-temperature error.
- There is smoke unrelated to normal food spill residue.
- The door, gasket, control panel, or wiring is visibly damaged.
- A breaker trips or gas odour is present.
If the problem remains
Record the full model number, exact symptom, displayed code, and the safe checks completed. Then use official brand support or qualified service.

Common questions
Oven temperature is inaccurate: FAQs
Can an oven thermometer confirm calibration?
A suitable oven thermometer can show trends, but readings fluctuate during normal cycling. Follow the thermometer instructions and compare multiple cycles.
Why does convection cook faster?
Convection moves heated air around the food and may require a lower temperature or shorter time depending on the recipe and model.
Should I adjust calibration after one bad meal?
No. First repeat a controlled test with full preheating, correct cookware, and the recommended rack position.
