Celsius and Fahrenheit use different numbers for the same condition. Confirm the displayed unit and whether the screen shows a target or a measured value before responding.
What the observation tells you
A unit change may make a familiar-looking setting appear very different. Missing segments or a small symbol can add confusion. Randomly lowering the digits may create an unintended selection without addressing the original concern.
A useful next step
Check the manual's unit option and use suitable independent monitoring if the display is unclear. Describe the full reading, including its minus sign and unit, when requesting advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
