The short answer
On a Livart refrigerator this almost always comes down to airflow or to the heat the unit is being asked to get rid of, not to a dead compressor. The first two checks below need no tools and no panel removed, and between them they settle most of these calls. The sealed system is the last thing to suspect, not the first.
What you observe
- The cabinet is warm but you can clearly hear the unit running — The compressor hum is there, the light works, and the air inside is simply not cold.
- The freezer side is still cold but the fresh-food side is not — That split is diagnostic on its own: the cold is being made and is not being moved where it needs to go.
- NEAR MISS — the unit is silent and nothing inside is cold — No hum, no fan, no light: that is a power, start-relay or control failure and it belongs on the page for a unit that will not start.
What goes wrong here, in order
- A door that is not sealing — A gasket that has hardened, torn, or been hung crooked lets a slow stream of room air into the cabinet. The unit answers by running longer and longer, and the cabinet still drifts warm — with frost building where the warm air meets the cold. Top of the list on this one: the door is the part of this unit that gets used hardest, and the test for it takes one sheet of paper. Livart compacts use a light reversible door, and a reversible door that has been hung on the other side is one of the commonest reasons a compact stops sealing.
- The room it stands in and the air behind it — A refrigerator does not destroy heat, it moves it into the room. Stand one in a hot garage, box it into a surround, or push it back against a wall so the coil cannot breathe, and the cabinet warms up while the unit runs flat out. Second on this brand: it is quick to rule out and it changes nothing else you do if it turns out to be the answer.
- How the unit is being used — A cabinet packed solid has no air path; a cabinet nearly empty has nothing to hold the cold. Warm food loaded in quantity, or a door opened every few minutes, will keep any unit above temperature without anything at all being wrong with it. Third: it explains a minority of these, but it is worth ruling out before anything is taken apart.
What to check first, second, third
- Close the door on a sheet of paper and try to pull it out — Do it at several points around all four sides. Anywhere the paper slides free easily, the gasket is not gripping and warm air is getting in there.
- Put a hand behind and above the unit and feel for warm air moving away — Still, hot air trapped behind the cabinet means the unit is recycling its own heat, and nothing else you check will matter until that is fixed.
- Look at how full the cabinet is and where the air vents are — A vent blocked by a box or a stack of containers starves one section while the rest of the cabinet stays cold, which looks exactly like a cooling failure from the outside.
The owner checks, step by step
- Clean the gasket and the frame it seals against with warm soapy water — Sticky residue and crumbs hold a gasket open. Check afterwards with the paper test at each corner and along the hinge side.
Tools: cloth, mild detergentAbout 15 min
- Pull the unit forward and clear the space behind and above it — Give it the clearance the manufacturer's installation instructions ask for, then leave it to run for a few hours before judging it.
Tools: a helper for a full-size cabinetAbout 20 min
- STOP here if the next step needs a panel off or a meter on live terminals — Naming the likely cause is the useful outcome of an owner check; getting behind the panel is a different job with a different set of risks.
Before anything comes apart
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Do not try to chip ice off an evaporator with a knife or a screwdriver: the tubing behind it is soft aluminium, and a puncture turns a cheap fault into a sealed-system repair. Leave the door switch alone.
When this becomes a service call
The line is the rear panel of the freezer. Everything in front of it is an owner check; everything behind it involves live terminals, a sealed refrigerant circuit, or both. Call sooner rather than later if the cabinet cannot hold 40 °F (4 °C) at all, because the food loss usually costs more than the diagnosis.
