Preset programs do not seem to match expected cooking times or temperatures.

Safety first: This issue is usually not a safety concern but can affect cooking results.

Steps to address preset mismatch:

• Consult manual: Verify the intended time and temperature for each preset in your Kalorik model's user manual.
• Use manual settings: If presets are not suitable, switch to manual temperature and time control to achieve desired results.
• Check temperature accuracy: Place an oven thermometer in the basket and compare actual temperature to the set value. If there is a large discrepancy, inspect and possibly replace the NTC temperature sensor or control PCB.

Firmware presets are not user-adjustable; hardware replacement is only needed if actual temperatures are significantly off.
