When a refrigerator stops cooling while the freezer stays cold, it is almost never a dead compressor — it is usually a defrost or airflow problem starving the fresh-food section of cold air. The good news is that these are common, well-understood repairs.
Why your refrigerator is not cooling
- Evaporator fan failure — the fan that pushes cold air from the freezer into the fridge has stopped; you may hear silence or a clicking.
- Defrost-system fault — a failed defrost heater, thermostat or control lets frost choke the evaporator coil until airflow stops.
- Condenser coils caked in dust or pet hair — the system cannot shed heat, so it runs constantly and cools poorly.
- Sealed-system or compressor fault — less common, but a refrigerant restriction or a failing inverter compressor needs EPA-certified diagnosis.
What you can safely check first
- Confirm the temperature dial or panel was not bumped, and nothing is blocking the interior vents.
- Pull the fridge out and vacuum the condenser coils (usually behind or beneath the unit).
- Listen for the evaporator fan running when the doors are closed (press the door switch).
When to call a technician
If the coils are clean and the fridge still will not cool within a few hours, it is time for a diagnosis. Our factory-trained technicians test the defrost circuit, fan and sealed system and repair it to spec — see our refrigerator repair service for details, or call for same-day help before your food spoils.

Refrigerator Not Cooling — FAQs
Why is my fridge warm but the freezer still cold?
That specific split almost always points to a defrost-system fault or a failed evaporator fan blocking cold air from reaching the fresh-food section — not a dead compressor. It is a common, fixable repair.
How long can food stay safe if the fridge stops cooling?
Roughly four hours if you keep the door shut. After that, perishable food is at risk, which is why we prioritize no-cooling calls for same-day service when we can.
