The short answer
On the BCD line, the most common reason a refrigerator is not cooling is evaporator fan motor failed or obstructed. On this page that cause is ranked ahead of airflow blocked by a frosted evaporator, which is where the order departs from the brand-generic article above; the ranking below says what about this platform moved it. Two of the three causes below are owner-checkable with no tools worth naming, and the last of them is a service call.
What you see on the BCD line
- Food spoiling faster than the display suggests it should — Trust a thermometer on a shelf over the panel reading; a failed sensor lies to the panel first and to you second.
- The cabinet is warm but the unit is clearly running — The compressor hum is there and the light comes on, yet the air inside is no colder than the room after several hours.
- A sheet of frost on the freezer rear wall — Not the light dusting a freezer normally carries, but a continuous white slab over the panel that hides the evaporator.
- The freezer is still cold but the fresh-food side is not — A split like this points at airflow between the two compartments rather than at cooling itself, and it is the single most useful thing you can notice.
- NEAR MISS — the unit is silent and the light is out — That is a power, cord or main-board fault, not a cooling fault, and it is a different page.
Causes, most likely first on the BCD line
- Evaporator fan motor failed or obstructed — The fan behind the freezer panel is what pushes cold air where it is wanted. When it stops, the evaporator still gets cold and the cabinet still gets warm, which is why this fault is so often mistaken for a dead compressor. It sits near the top because it is the cheapest part in the chain and the one that most often explains a freezer that is fine over a refrigerator that is not. The BCD key covers a single model, so nothing on this page has to be qualified across capacities or configurations.
- Airflow blocked by a frosted evaporator — The defrost cycle stops clearing the evaporator, frost builds into a slab, and the slab blocks the only path cold air has into the cabinet. The unit keeps running because the sensor it trusts never sees the temperature it wants. It is the only common fault that keeps everything sounding perfectly normal while the cooling stops reaching the food.
- Sealed-system or compressor fault — When the refrigerant circuit is the problem, no amount of cleaning or defrosting changes anything: the system is running and making no cold at all. It stays last because it is the least likely of the group, the most expensive, and the only one that is not an owner repair under any circumstances.
Check in this order, and why
- First: Open the freezer and listen with the door switch held in — A fan you cannot hear when the light is defeated is a fan that is not turning. It comes first because it is the cheapest of the three to exclude and because everything below it is harder to read while it is unresolved.
- Second: Look behind the freezer rear panel for a frost slab — If the panel is cold to the touch and edged with ice, this is your cause and the rest of the list can wait.
- Third: Only after the checks above: is the condenser cold and the evaporator dry? — This is where owner diagnosis ends; refrigerant work is licensed work.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Keep sharp tools away from the evaporator and from the aluminium tubing under the liner — both are thin-walled, and a puncture vents the refrigerant charge in seconds. If you find oil where there should be none, stop: oil outside the tubing means the sealed system is open and the unit should be switched off rather than left running.

When to call a technician
Call once the airflow and condenser checks are clean, because everything left needs a meter on live terminals or gauges on the sealed system. Call immediately, without finishing the list, if you smell burning, see oil at the compressor or hear the compressor try to start and trip repeatedly — that pattern damages the part that is trying to start.
