Compare positions
Identify where affected food was stored and whether neighbouring items behaved normally. Include the selected setting and any recent adjustment without repeatedly changing it for testing.
What inspection can establish
A suitable assessment can consider controls, sensing and airflow arrangements for the model. It cannot infer a single failed part from a frozen lettuce or promise a repair before the cause is known.
A useful distinction
A colder setting affects the whole intended storage environment, while a local cold spot may affect only items touching a particular surface. That difference helps frame a control enquiry without a remote temperature diagnosis.
