What this usually is
On a l2 refrigerator, running without cooling is usually dirty condenser coil or no clearance around the cabinet rather than a failed compressor. Air stops moving, the cabinet warms while the unit runs, and the machinery is fine. Most of the causes below are owner-checkable in minutes; only the last needs a technician.
What this looks like
- The freezer is cold but the fresh-food side is not — Cold is being made. Something is stopping it from getting where it is needed, which narrows the list sharply.
- The outside of the cabinet feels warm near the hinges — Some warmth there is normal; noticeable heat with a warm interior points at heat that is not being rejected.
- Frost building up on the back wall of the freezer — A sheet of ice rather than the usual light dusting means air is no longer passing over the coil.
- NEAR MISS — only the icemaker has stopped, the food is cold — If the cabinet holds temperature and only the ice has stopped, this is an ice-production fault and a different page covers it.
What goes wrong here, in order
- Dirty condenser coil or no clearance around the cabinet — Every refrigerator is a heat pump, and a heat pump that cannot reject its heat cannot make cold. A blanket of dust on the condenser is exactly that failure, expressed in the cheapest possible way. It leads because this cabinet reaches it before it reaches anything else, and because the check needs no tools. On a badge this size the parts channel is thin, so the ranking is written around what can be checked and corrected without a part on order.
- Blocked airflow from a frosted evaporator — Cold reaches the food compartment as moving air, not by radiating through the walls. When the evaporator ices up, that air path closes, and the cabinet warms steadily even though the compressor is working exactly as designed. It sits second: less common than the one above, but still ahead of anything that needs a meter.
- Failed evaporator or condenser fan motor — Two fans matter here. The evaporator fan pushes cold air into the cabinet; the condenser fan pulls room air across the hot coil. Lose either and the symptom is the same warm cabinet with a compressor that never stops. Third: the checks above will usually have found the fault before this one is reached.
- A leak or blockage in the sealed refrigeration circuit — A sealed circuit that has lost charge or blocked cannot be judged from outside, which is precisely why it belongs at the end of a list of things that can be judged from outside. At the foot of the list, on likelihood alone.
The order to check in
- Feel the air coming out at the base grille while it is running — Warm exhaust that has nowhere to go, or none at all, tells you which half of this cause you have. First, because it separates the top two causes in under a minute.
- Take out the freezer drawer or baskets and look at the rear panel — Frost on the panel, or ice visible through its vents, is the answer. A light dusting is normal; a solid sheet is not. Second, once the first check is clean.
- Look through the base grille at the condenser fan while the unit runs — A blade that is stationary, or one that is fouled by dust and debris, is visible without taking anything apart. Last of the owner-side checks; anything past it belongs to a technician.
What an owner can safely check
- Vacuum the condenser coil and the fan grille, then restore the clearance — Give it the gap the manual asks for at the back and the sides before pushing it home again.
Tools: vacuum, soft brushAbout 25 min
- Clear the freezer vents and check the rear panel for a frost sheet — Unpack the freezer down to the back wall so the air paths are actually visible.
About 20 min
- Press the freezer door switch and listen for the fan to start — Do it with the light on and off so you can tell which sound is which.
About 5 min
- STOP if the fault is now down to a sealed or high-voltage part — Those need tools, training and a discharge procedure. Write down what you found and hand it over.
The part that is not optional
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Never chip ice off a coil or a liner with a knife or a screwdriver: the tubing behind it is thin, and puncturing it releases the charge and ends the life of the cabinet. Let ice melt on its own.
When to call a technician
Stop and call when the checks above are clean, when a fan is silent and the panel must come off to reach it, or when the coil never warms. Call the same day if there is oil at the compressor: the circuit is open, and every hour it runs after that makes the repair worse.

What this page leaves out
This page is deliberately generalized across the l2 refrigerators it covers. It does not carry model-specific wiring, torque values or component resistance figures — those belong on the page for your family, and that page takes precedence where it exists.
