A refrigerator that runs continuously but stays warm can have several possible causes. The first step is to distinguish an airflow problem from a defrost or sealed-system issue. The observations below illustrate a field diagnostic process, not a confirmed repair outcome.

A field example: cooling trouble and an intermittent evaporator fan
On a refrigerator service visit, the compressor and condenser fan operated, and the evaporator coil began getting cold. However, the evaporator fan was not turning initially. After the fan blade was nudged, it started; following a restart, it also started on its own. This pattern suggests an intermittent fan or control issue worth testing, but it does not prove which part is defective.
Why the evaporator fan matters
The evaporator fan circulates cold air from the evaporator through the refrigerator compartment. If it stalls, temperatures can rise even while the compressor is running. A fan that works after a restart may still fail intermittently. Door switches, fan supply voltage, wiring, ice interference and control behavior should be checked before replacing components.
Other checks before ordering parts
- Measure freezer and fresh-food temperatures after sufficient run time.
- Inspect the evaporator for excessive ice buildup and check whether the defrost system operates correctly.
- Verify fan power and whether the fan should be running in the current operating mode.
- Check condenser airflow, door seals and air passages.
- If frost forms only near the evaporator inlet, investigate refrigerant-flow and sealed-system performance rather than assuming a fan is the only problem.
These symptoms can overlap. An accurate diagnosis depends on the appliance model and measurements taken under the correct conditions.
