Smeg fridge freezer fridge not cold but freezer working, any ideas?

If the freezer is still working properly but the fridge has gone warm, that usually means the cooling system is still producing cold and the fault is more likely with air circulation, a flap/damper problem, icing, or a control issue rather than the sealed system itself. On a one-year-old Smeg, it is usually worth investigating before replacing.

Before checking anything internal, isolate the appliance from the mains.

1. Check for obvious airflow issues Make sure vents inside the fridge and freezer are not blocked by food or packaging. On many frost-free models, the fridge is cooled by cold air blown or directed from the freezer, so restricted airflow can leave the fridge warm.

2. Listen for the evaporator fan Open the freezer and listen for a fan running (some stop when the door is open, so press the door switch in). If the fan is not running, the fridge section may not receive cold air.

3. Look for ice build-up If the back panel inside the freezer has a heavy frost or ice behind it, the evaporator may be iced up. That often points to a defrost fault rather than a gas issue. A full manual defrost for 24-48 hours with doors open can sometimes temporarily restore operation.

4. Check the air damper/flap If fitted, the damper between freezer and fridge can stick shut, stopping cold air entering the fridge.

5. Check temperatures and controls Confirm the fridge temperature setting has not changed and note actual freezer performance. If the freezer is very cold but fridge warm, that supports an airflow/control fault.

At only a year old, also check warranty or retailer rights first. If internal electrical testing, sealed refrigeration, or strip-down is needed, use a qualified engineer.
