The new appliance may use different modes, shelf numbering or cookware guidance. A familiar temperature number alone does not reproduce all the conditions of the previous oven.
What the observation means
A fan setting in one oven may not match the same-looking symbol in another. The cavity size, recommended preheat method and tray position can also differ. Start by translating the recipe into the new model's instructions rather than assuming its controls are inaccurate. This is especially useful when the appliance is already installed in a newly occupied home.
A useful next step
Locate the model reference and correct manual, then review the cooking chart for the type of food concerned. Note any genuine warning, damaged part or sudden interruption separately. Do not continue using an appliance with safety concerns simply because you are still learning its controls or comparing it with the previous kitchen.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
