Its heating pattern and intended preparation method can differ from an ordinary oven set low. The function name does not make every slow-cooker recipe directly transferable.
What the observation means
Food quantity, vessel and any required preparation stage matter. A warming drawer is not necessarily a slow-cooking oven, even on the same range.
A useful next step
Use the manufacturer's method alongside appropriate food-safety guidance. Do not compensate for uncertain performance by leaving food in a lukewarm cavity indefinitely. If a familiar approved preparation changes, record the cavity, setting and starting conditions rather than assuming that all low-temperature cooking behaves alike.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
