Check whether the model ends the mode automatically and what its indicator means. A prolonged stronger mode can change running time and noise without being a repair diagnosis.
What the observation tells you
Do not assume every illuminated snowflake means the same thing. Some panels show a selected mode separately from temperature, while others cycle through displays. Random button presses can select a different setting accidentally.
A useful next step
Use the documented cancellation process where appropriate and return to the recommended normal setting. If the indication remains unexpectedly or temperature control is unreliable, report the exact display and how the mode was selected.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
