DEEPER REPAIR GUIDANCEInvestigating multi-zone cooling without guesswork
A four-door refrigerator may use independent air passages, sensors and cooling commands for different drawers. When only one section warms, exchanging the entire compressor or adding refrigerant is unlikely to be a sensible first intervention. We inspect the functional path for that zone: is it being asked to cool, can cold air reach it, are door switches sending the right signals and is frost blocking the passage? A dispenser fault may coexist with a temperature fault but must be traced separately. After a power cut, compare the controller warning with actual temperature over time. Restoring normal display lights alone does not establish that stored food is safe.
