Why can a refrigerator compartment be warm while the freezer is still cold?
Separate a loading problem from a persistent fault
Look for food pressed against the air openings identified in your manual. Clear ordinary packages from those openings without removing covers. Note whether the problem began after a large grocery load, a door left ajar or a settings change. If the vents are clear and the temperature remains wrong after the manual's recovery period, arrange appliance service rather than repeatedly choosing a colder setting.
