Yes, on ovens that allow both units. Check the unit shown on the display before interpreting an unfamiliar number as an overheating or thermostat problem.
What the observation means
Recipes, imported cookbooks and appliance settings may use different temperature scales. The same number represents different conditions on those scales, so a copied setting can be inappropriate even when the oven follows it correctly. A temperature-unit preference may also change after a reset. This is a settings check, not a reason to assume the appliance is healthy if other warning signs are present.
A useful next step
Compare the displayed unit with the recipe and the manual. Use a reliable conversion where necessary rather than estimating by the size of the number. If the unit is correct but the cooking behaviour has changed, record the mode and target separately. Do not touch the cavity or heating parts to decide whether the displayed temperature is believable.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
