Short version: check a fan that has stopped turning first. On a Kova refrigerator the common causes of a warm cabinet are all upstream of the machinery, and all but one of them can be settled in a few minutes with the doors open.
What the refrigerator is actually doing
- Food in the door spoils before food at the back — The door is the warmest place in any cabinet, so it fails first when the whole cabinet is drifting warm.
- 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.
- Condensation or sweating inside the fresh-food compartment — Warm humid air is getting in and meeting cold surfaces, which happens when the cabinet cannot hold its setting.
- NEAR MISS — it cools fine but cycles loudly every few minutes — Noise with normal temperatures belongs on the noise page, not this one. Temperature is the test that decides which page you are on.
Causes, most likely first on a Kova refrigerator
- A fan that has stopped turning — A fan is the part with bearings in a box that has almost no other moving parts, so it is the mechanical failure that actually happens. It usually complains first: a tick, a whirr or a rattle for weeks before it stops. Top of the list, because everything below it is harder to check and less likely to be the answer. This is a smaller badge rather than a platform of its own, so service documentation and parts are harder to come by — which pushes supply, installation and the consumables above component failure in the order below.
- Blocked airflow from a frosted evaporator — Cold air is the delivery mechanism in a refrigerator, and the evaporator is where it is made. Ice over that coil does not stop the cold being produced; it stops it being moved, which is why the freezer can stay cold while the fresh-food side warms. It takes second place because the check is quick and because leaving it unchecked makes everything below it harder to read.
- Dirty condenser coil or no clearance around the cabinet — It is also the failure that builds invisibly: the coil is at the back or underneath, in the dustiest part of the room, and nobody looks at it until something goes wrong. This far down the list because it needs the two above ruled out before the evidence for it means anything.
- Compressor, start device or the sealed circuit itself — When the circuit loses its charge or blocks, cooling falls away gradually rather than stopping outright, which is exactly why the cheaper causes above have to be eliminated before anyone concludes this one. Bottom of the order, because reaching it means the three likelier answers were already wrong.
What to check first, second, third
- Listen at the freezer with the door open and the door switch pressed in — The evaporator fan should run. Silence there, with a running compressor, is a strong result. Begin with this one; everything after it depends on what you find.
- Hold your hand at the fresh-food vents with the door open and the fan running — No air movement at the vents, with a cold freezer, points straight at a blocked coil or a stopped fan. Then this — it is the next cheapest thing that can be wrong.
- Pull the cabinet out and look at the coil at the back or underneath — If you cannot see metal through the dust, that is the fault. Look at the gap behind and above the cabinet at the same time. Third, and only if the two above found nothing.
What you can do yourself
- Clear debris from around the condenser fan blade through the base grille — Anything that has been pulled in from the floor can stop a blade without damaging the motor.
Tools: vacuumAbout 15 min
- Empty the cabinet and leave both doors open for a full manual defrost — Cold restored afterwards confirms the defrost system as the cause rather than the mechanism.
Tools: towels, coolerAbout 90 min
- Clear whatever sits on top of and behind the cabinet — Boxes on the lid and a bag jammed behind it are the most common version of no clearance.
About 10 min
- STOP when the next thing to move is a fixing rather than a cover — Anything held by fasteners is holding something in place for a reason. Write down what you found and leave it there.
Before you open anything
Safety
Switch the power off at the plug or the breaker before anything comes apart, and leave it off while you work. A refrigerator carries a capacitor that holds a charge after the power is off, and the door switch is there to cut the fan for a reason — never defeat it to keep the light or the fan running while your hands are inside.
When this becomes a service call
The line is simple: anything you can reach without a meter is yours, and anything on the sealed system is not. A refrigerator that is drifting warm is a same-week job rather than a same-month one, because the food in it is worth more than the visit.

What you are reading is written for the class, not for one Kova model. A family- or model-specific page, where one exists, carries what this page cannot: the exact part numbers, the board layout and the disassembly order for that line. Go there first if your model is named.
