An incomplete character can make a setting or warning easy to misread. Preserve a clear photograph from ordinary access and avoid guessing which number was intended.
What the observation tells you
A missing segment is a display observation, not proof that the temperature sensor is wrong. It may also make comparing the screen with an online error-code list unreliable. Repeated button presses can erase a useful warning or change the selected condition.
A useful next step
Check the manual's symbol chart and monitor storage appropriately. Provide the photograph and full model reference for assessment. Do not order a control module solely from the appearance of one incomplete digit.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
