The short answer
You are looking at a Appliance Support refrigerator that is not cooling, or cooling in one compartment only. The short version is below. On almost every domestic cabinet this is an airflow or a defrost problem long before it is a dead compressor, because the fresh-food side is cooled by air pushed off a single evaporator that lives behind the freezer wall. The checks that separate the two are owner work; anything that ends inside the sealed system is not. We hold no model-level fault data for Appliance Support refrigerators, so the ranking below is by mechanism for this appliance class rather than by anything specific to the badge on the door.
What you are actually seeing
- The freezer is still hard-frozen but the fresh-food side is warm or only cool — Means: air is being made cold and is not arriving — a fan, a damper or a blocked duct, not a refrigerant fault
- Both compartments are drifting warm together over a day or two — Means: either the cabinet is running and not removing heat, or it is barely running at all
- The compressor runs continuously and the cabinet never satisfies — Means: heat is getting in faster than it comes out, or the evaporator has iced over and lost its surface
- A rime of frost has built up on the rear freezer panel — Means: the defrost cycle is not clearing the coil — the single most common route to a warm fresh-food side
- The cabinet is silent and the interior light still works — Means: the compressor is not being asked to run, or it is being asked and failing to start
- Not this fault: Cold enough, but water pooling under the crisper — Means: a different fault — Page: appliance-support-refrigerator-water-leak
- Not this fault: Cold enough, but the ice maker has stopped filling — Means: a different fault — Page: appliance-support-refrigerator-ice-production
- Not this fault: Dark panel, no light, nothing at all — Means: a different fault — Page: appliance-support-refrigerator-wont-start
The likely causes, in order
- Evaporator iced over because the defrost cycle has failed — Why this rank: ranks first because a frosted coil produces exactly this pattern — a cold freezer, a warm fresh-food side and a compressor that will not stop — and because the defrost heater, its thermostat and its sensor are the cheapest parts in the cold chain to fail — Tells: a slab of frost on the rear freezer wall, a fan that sounds like it is chopping at ice, and a cabinet that recovers for a day after the door is left open to thaw
- Evaporator fan not turning, or turning against an obstruction — Why this rank: second because it produces the same one-sided warmth as an iced coil, and it is the failure a reader can confirm in a moment by listening at the open freezer with the door switch held in — Tells: no air movement at the freezer vents, or a fan note that rises and falls as the blade catches
- Condenser coil and condenser fan blocked with dust and pet hair — Why this rank: third, and rising in any household with animals or a tight cabinet surround; a coil that cannot reject heat makes the compressor run without ever satisfying — Tells: a hot, hard-to-touch cabinet side or back, and a visible mat of dust on the coil under or behind the unit
- A door left ajar, or a seal that no longer pulls the door closed — Why this rank: fourth because it mimics a cooling fault exactly and is invisible until you look for it — humid room air is a heat load and a frost source at the same time — Tells: condensation at the door mouth, frost only near the hinge side, and a door that does not self-close from a hand-width open
- Damper or air diffuser between the compartments stuck shut — Why this rank: fifth: it starves the fresh-food side alone, but it is behind a panel and less often the culprit than a fan or a frosted coil — Tells: freezer at temperature, no air at the fresh-food vent even with the fan clearly running
- Control board or thermistor reporting a temperature the cabinet does not have — Why this rank: sixth: a sensor reading cold when the box is warm stops the cabinet calling for cooling at all, and the symptom looks like a dead machine that is in fact obeying a lie — Tells: a displayed temperature that does not track a thermometer left inside overnight
- Compressor start relay, capacitor or the compressor itself — Why this rank: last, and genuinely last — this is the failure everyone reaches for first and the one that accounts for the fewest calls of this kind — Tells: a click every few minutes with no run note following it, and a compressor body that is hot but silent
- Platform note: On a compact or under-counter cabinet the order changes: there is usually no forced-air duct between compartments and often no separate defrost heater, so the damper and evaporator-fan causes drop out, and door seal, condenser dust and ambient heat move to the top.
What to check, and why in that order
- Put a thermometer in a glass of water in the fresh-food compartment and another in the freezer, and read them both after they have settled overnight — Because: the whole ranking above depends on which compartment is failing, and a door-mounted display is not evidence of what the shelf is doing
- Open the freezer, hold the door switch in, and listen for the evaporator fan — Because: it separates the top two causes from each other and from everything below them in one action
- Look at the rear freezer panel for frost build-up before you look anywhere else inside — Because: a frosted coil explains a stopped fan as well as a warm cabinet, so finding it re-orders everything below it
- Pull the unit out and look at the condenser coil and its fan — Because: a blocked coil is the cause that costs nothing to fix and is invisible from the front
- Close the door on a slip of paper at several points around the seal and try to pull it out — Because: it converts a vague suspicion about the gasket into a repeatable result
- Only then consider the sealed system — Because: every cause above it is verifiable without a gauge set, and the sealed system is not owner work in any case
What you can safely do yourself
- Confirm the fault with a real thermometer — N: 1 — Stand a glass of water in the fresh-food compartment and a thermometer in the freezer. Leave them overnight without opening the door. Compare against the food-safety targets in the safety section below. — Tools: a fridge thermometer or any glass thermometer — Time: quick to set up, then an overnight wait
- Listen for the evaporator fan — N: 2 — Open the freezer and press and hold the door switch or plunger so the cabinet thinks the door is shut. You should hear a fan spin up within moments and feel air at the vents. — Tools: none — Time: quick
- Inspect the rear freezer panel for frost — N: 3 — Empty the freezer shelves and look at the back wall. A light dusting is normal. A continuous white slab, or ice grown out past the vents, means the defrost cycle is not clearing the coil. — Tools: a torch — Time: short
- Clean the condenser coil and check its fan — N: 4 — Unplug the cabinet first. Pull it out, take off the rear or lower access cover, and vacuum the coil and the fan blade clean. Spin the blade by hand to confirm it turns freely. — Tools: a vacuum with a brush head, a coil brush, a nut driver — Time: moderate
- Test the door seal all the way round — N: 5 — Close the door on a strip of paper and pull. Repeat at the top, the bottom, the handle side and the hinge side. A strip that slides out with no drag marks a dead section of gasket. — Tools: a strip of paper — Time: quick
- Give the cabinet room to breathe and re-measure — N: 6 — Restore the clearance the manufacturer specifies at the back and sides, reload the cabinet without blocking the vents, and repeat the overnight measurement before you conclude anything. — Tools: none — Time: quick, then an overnight wait
- Stop condition: Stop at the point where the next step is a meter on live terminals, a defrost heater resistance test, or anything that requires opening the sealed refrigeration circuit.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The sealed refrigeration system is under pressure and contains refrigerant. Opening it is licensed work, not owner work. A refrigerator holds food safely at 40 °F (4 °C) or below. A freezer holds food safely at 0 °F (−18 °C) or below. No step on this page defeats a door interlock, and none should be adapted to. unplug-before-service fridge-40f freezer-0f

When to call a technician
The line is not the size of the part; it is whether the next diagnostic step needs a meter on a live circuit or a gauge on a sealed one. Everything above that line is a household job with a vacuum and a torch. Everything below it is licensed work, and on refrigerant in particular it is licensed work by law rather than by preference. A blocked or dusty condenser coil A door that is not closing, or a gasket that has taken a set Vents blocked from inside by stored food A cabinet crowded against a wall or a heat source A manual defrost to confirm an iced coil Frost returns on the rear panel within days of a manual defrost The evaporator fan is silent with the door switch held in The compressor clicks and does not run Any suspicion of a refrigerant leak or a restricted capillary A displayed temperature that disagrees with a thermometer on the shelf
